Translated fromChinese技术领域technical field
本发明涉及对等网络领域，尤其涉及一种资源节点信息通知方法及网络实体装置。The invention relates to the field of peer-to-peer networks, in particular to a resource node information notification method and a network entity device.
背景技术Background technique
目前，对等网络（Peer to Peer，P2P）业务在网络中所占的流量越来越大。P2P业务流量大量占据骨干网以及由此产生跨网流量的问题，对运营商的网络设备负担及运营成本带来了很大的挑战。At present, peer-to-peer (Peer to Peer, P2P) services account for more and more traffic in the network. A large number of P2P business traffic occupies the backbone network and the resulting cross-network traffic poses a great challenge to operators' network equipment burden and operating costs.
在当前P2P业务流量占互联网统治地位的状况下，低级骨干互联网运营商网络受到上述挑战显得尤为严重。In the current situation where P2P business traffic dominates the Internet, the above-mentioned challenges to the low-level backbone Internet operator networks are particularly serious.
以目前P2P应用中的常见的比特流（Bitorrent，BT）下载业务为例，这种业务技术是基于索引服务器（Tracker）的网状网（Mesh）的传输模式。如图1所示，当ISP2网络中的标识为User的用户需要下载资源文件时，需要先到外网的BT资源发布网站上查找并获取资源描述文件，然后根据资源描述文件的指示通过网络之间的核心路由器（Core Router）在ISP1网络中索引服务器（Tracker）中获取资源下载节点的列表（SeedList），假定资源文件分成Data1、Data2和Data3三部分，根据Data1，Data2和Data3的索引，可以从正在同时下载该文件的所属资源节点User1、User2和User3分别下载所需要的资源文件。如图1所示，用户User可以从ISP1中的标识为User1的节点下载Data1，从ISP1中标识为User2节点下载Data2，以及从ISP2中的标识为User3的节点下载Data3。Take the common Bitorrent (BT) download service in the current P2P application as an example, this service technology is based on the transmission mode of the Mesh network of the index server (Tracker). As shown in Figure 1, when a user identified as User in the ISP2 network needs to download a resource file, he needs to first search for and obtain the resource description file on the BT resource release website on the external network, and then pass the resource description file through the network according to the instructions of the resource description file. The core router (Core Router) in the ISP1 network obtains the resource download node list (SeedList) from the index server (Tracker) in the ISP1 network. Assume that the resource file is divided into three parts: Data1, Data2 and Data3. According to the indexes of Data1, Data2 and Data3, you can The required resource files are respectively downloaded from the resource nodes User1, User2 and User3 which are downloading the file at the same time. As shown in FIG. 1 , User can download Data1 from a node identified as User1 in ISP1, download Data2 from a node identified as User2 in ISP1, and download Data3 from a node identified as User3 in ISP2.
如果资源文件下载的目的节点和源节点不属于同一运营商的网络，例如，资源文件下载的目的节点（用户User）属于互联网服务提供商（Internet ServiceProvider，ISP）2的网络，而源节点User1和User2则属于ISP1的网络，此时资源文件的点对点传输就会造成产生不同运营商之间的跨网络流量。If the destination node and the source node of the resource file download do not belong to the network of the same operator, for example, the destination node (User) of the resource file download belongs to the network of Internet Service Provider (ISP) 2, and the source node User1 and User2 belongs to the network of ISP1. At this time, the point-to-point transmission of resource files will cause cross-network traffic between different operators.
若ISP2为低级骨干运营商网络，ISP1为高级骨干运营商网络，由于大量互联网络资源基本上都集中在高级骨干运营商网络ISP1内，低级骨干运营商网络ISP2网内的网络资源并不丰富，并且索引服务器所提供的资源下载列表中的资源节点往往是随机分配的，也就是说，索引服务器所提供的资源下载列表中的资源节点通常会较多数位于骨干互联网运营商网络中，这样的话，就会导致低级骨干运营商网络ISP2的用户需要经常访问高级骨干运营商网络ISP1网络中的资源，由此产生巨大的P2P业务跨网流量，大大增加了低级骨干运营商网络ISP2的网络设备负担，增加了其运营成本，并且过多的P2P跨网络流量也会造成两个运营商网络之间的通信瓶颈。If ISP2 is a low-level backbone operator network, and ISP1 is a high-level backbone operator network, since a large amount of Internet resources are basically concentrated in the high-level backbone operator network ISP1, the network resources in the low-level backbone operator network ISP2 network are not abundant. And the resource nodes in the resource download list provided by the index server are often randomly assigned, that is to say, the resource nodes in the resource download list provided by the index server are usually located in the backbone Internet operator network. As a result, users of the low-level backbone operator network ISP2 need to frequently access the resources in the high-level backbone operator network ISP1 network, resulting in huge P2P service cross-network traffic, which greatly increases the network equipment burden of the low-level backbone operator network ISP2. It increases its operating cost, and too much P2P cross-network traffic will also cause a communication bottleneck between the two operator networks.
现有的降低跨网流量的解决方案如P2P缓存（P2P Cache）方案，通过运营商在本网内的转接点链路（Transit Link）或者关键汇聚点设置一些缓存（Cache）节点，这些节点使用专门的硬件、存储和相关软件，对流过本网的P2P业务数据内容进行存储。这样，当其他网内的P2P业务用户再次请求访问该业务数据内容时，网络可以透明地将请求导向P2P缓存节点，利用缓存节点存储的业务数据内容提供服务。这样，很大一部分流量都能限制在网内传输，从而降低跨网流量。Existing solutions to reduce cross-network traffic, such as P2P cache (P2P Cache) scheme, set some cache (Cache) nodes through the operator's transit point link (Transit Link) or key convergence point in the network, these nodes Use specialized hardware, storage and related software to store the P2P business data content flowing through this network. In this way, when P2P service users in other networks request to access the service data content again, the network can transparently direct the request to the P2P cache node, and use the service data content stored in the cache node to provide services. In this way, a large part of traffic can be restricted to be transmitted within the network, thereby reducing cross-network traffic.
但上述方法存在下列的问题：But the above method has the following problems:
P2P Cache需要在本网内的转接点链路或者关键汇聚点都设置P2P Cache设备，价格比较昂贵；同时由于需要进行内容的缓存，因此需要投资较多的存储设备，所需耗费的成本较高。P2P Cache needs to set up P2P Cache devices on the transfer point links or key convergence points in the network, and the price is relatively expensive; at the same time, due to the need to cache content, it needs to invest in more storage devices, and the cost required is relatively high. high.

On the premise of reducing the cross-network P2P data transmission traffic as much as possible, the cross-network P2P data transmission is further optimized. efficiency and economy.

具体实施方式Detailed ways
下面结合附图，用具体实施例对本发明提供的一种资源节点信息通知方法及网络实体装置进行详细的说明。A method for notifying resource node information and a network entity device provided by the present invention will be described in detail below with reference to the accompanying drawings.
为了便于说明本发明实施例提供的一种资源节点信息通知方法，本发明实施例还是分别以图1所示的两种不同类型网络ISP1网络和ISP2网络为例进行说明。In order to facilitate the description of a method for notifying resource node information provided by the embodiment of the present invention, the embodiments of the present invention are described by taking two different types of networks ISP1 network and ISP2 network shown in FIG. 1 as examples.
对于ISP1这种高级骨干运营商网络来说，与现有技术相同，在ISP1网络内部的索引服务器（可以不止一个）存储有各个资源对应的资源节点信息，该资源节点信息的内容包括各资源节点的IP地址、端口和用户ID等信息。For an advanced backbone operator network such as ISP1, similar to the existing technology, the index server (can be more than one) inside the ISP1 network stores resource node information corresponding to each resource, and the content of the resource node information includes each resource node information such as IP address, port, and user ID.
如图2所示，对于ISP1网络来说，本发明实施例所提供的资源节点信息通知方法，具体包括以下步骤：As shown in Figure 2, for the ISP1 network, the resource node information notification method provided by the embodiment of the present invention specifically includes the following steps:
步骤S201、ISP1网络中的索引服务器接收本网用户端发起的获取请求，该获取请求用于获取所需资源对应的资源节点信息。Step S201 , the index server in the ISP1 network receives an acquisition request initiated by the client of the network, and the acquisition request is used to acquire resource node information corresponding to the required resources.
步骤S202、ISP1网络中的索引服务器根据该资源节点信息获取请求，确定出存储的资源节点信息中包含的本网资源节点信息，并根据各本网资源节点所属的子域网的流量负荷参数信息和各本网资源节点的自身服务能力信息，进一步选取所需返回的本网资源节点信息，返回给该用户端。Step S202, the index server in the ISP1 network determines the local network resource node information contained in the stored resource node information according to the resource node information acquisition request, and according to the traffic load parameter information of the sub-area network to which each local network resource node belongs and the self-service capability information of each local network resource node, and further select the local network resource node information that needs to be returned, and return it to the client.
该用户端根据返回的资源节点信息，分别向各个对应的资源节点发送建立连接请求，得到资源节点的许可后，即建立网状网进行资源的传输。According to the returned resource node information, the client sends a connection establishment request to each corresponding resource node, and after obtaining the permission of the resource node, establishes a mesh network for resource transmission.
在上述步骤S202中，ISP1网络中的索引服务器在确定出存储的资源节点信息包含的所有本网资源节点信息中，进一步地按照各本网资源节点所属的子域网的流量负荷参数信息，以及各本网资源节点的自身服务能力信息，选取需要返回的本网资源节点信息，最终将选取出来的本网资源节点信息返回给用户端。In the above step S202, the index server in the ISP1 network, after determining all the local network resource node information contained in the stored resource node information, further according to the traffic load parameter information of the sub-area network to which each local network resource node belongs, and The self-service capability information of each local network resource node selects the local network resource node information that needs to be returned, and finally returns the selected local network resource node information to the client.
本发明实施例中，如图3所示，ISP1网络中，预先分成若干个子域网，包括子域网A、子域网B、子域网C和子域网D。各子域网的内部结构如图4所示，在每个子域网中，可以配置一个或多个监测点（Detection Point，DP）；例如可以利用现有的DPI（Deep Packet Indentification）设备，每个监测点的作用是周期性地监测本子域网内的流量负载情况，统计本子域网内各节点上载或下载数据流量的总量，然后将统计出的本子域网内流量的总量除以本子域网内节点总数，得到本子域网的流量密度值。并且不断地将当前周期计算得到的流量密度值信息上报给ISP1网络中的索引服务器。In the embodiment of the present invention, as shown in FIG. 3 , the ISP1 network is pre-divided into several sub-area networks, including sub-area network A, sub-area network B, sub-area network C, and sub-area network D. The internal structure of each sub-area network is shown in Figure 4. In each sub-area network, one or more detection points (Detection Point, DP) can be configured; for example, existing DPI (Deep Packet Identification) equipment can be used to The function of each monitoring point is to periodically monitor the traffic load in the sub-area network, count the total amount of uploaded or downloaded data traffic of each node in the sub-area network, and then divide the total amount of traffic in the sub-area network calculated by The total number of nodes in this sub-area network to get the traffic density value of this sub-area network. And continuously report the traffic density value information calculated in the current period to the index server in the ISP1 network.
并且，ISP1网络中各子域网内的每个节点，也周期性地统计自身CPU平均使用率、内存平均使用率以及可用网络带宽等参数作为自身服务能力信息上报给ISP1网络中的索引服务器。Moreover, each node in each subnet in the ISP1 network also periodically collects its own CPU average usage rate, memory average usage rate, and available network bandwidth and other parameters and reports it to the index server in the ISP1 network as its own service capability information.
ISP1网络中的索引服务器将各子域网监测节点上报的各子域网的流量密度值信息，以及各节点上报的自身服务能力信息存储并不断周期性地更新。The index server in the ISP1 network stores and periodically updates the traffic density value information of each sub-area network reported by each sub-area network monitoring node and the self-service capability information reported by each node.
在选取本网资源节点时，索引服务器根据存储的上述信息，在存储的本网资源节点信息中，进一步地选择所属子域网流量密度值较低、自身服务能力较高的本网资源节点的相关信息返回给用户端。When selecting local network resource nodes, the index server further selects local network resource nodes with lower traffic density values in their sub-domain networks and higher self-service capabilities based on the stored information above and among the stored local network resource node information. Relevant information is returned to the client.
之所以按照上述原则进行选择，是因为在流量密度较低的子域网中，资源节点可能具有较高的上行带宽和较小的负载，服务能力高的资源节点具备更好为其他节点提供资源的能力。The reason for choosing according to the above principles is that in sub-area networks with low traffic density, resource nodes may have higher uplink bandwidth and smaller load, and resource nodes with high service capabilities are better able to provide resources for other nodes. Ability.
索引服务器综合上述所属子域网流量密度值信息、自身服务能力信息两项参数选取本网资源节点信息时，也可设定将上述两项参数优先级，例如各资源节点的服务能力信息优先于子域网流量密度值信息，在设定这样的优先级的情况下，假设图中，各子域网的流量密度值从小到大排列依次为：子域网A<子域网B<子域网C<子域网D，子域网A中的资源节点User 1和子域网B中的资源节点User 2都是备选的资源节点，如果资源节点User 2的服务能力大于资源节点User 1，那么，即使子域网A的流量密度值小于子域网B的流量密度值，索引服务器会优先选择资源节点User 2的信息返回给用户端。When the index server selects the resource node information of the local network based on the two parameters of the above-mentioned sub-network traffic density value information and its own service capability information, it can also set the priority of the above two parameters. For example, the service capability information of each resource node is prioritized over Sub-area network traffic density value information, in the case of setting such a priority, assuming that in the figure, the traffic density values of each sub-area network are arranged in ascending order: sub-area network A<sub-area network B<sub-domain Network C<subnet D, resource node User 1 in subnet A and resource node User 2 in subnet B are candidate resource nodes. If the service capability of resource node User 2 is greater than that of resource node User 1, Then, even if the traffic density value of subnet A is lower than the traffic density value of subnet B, the index server will preferentially select the information of resource node User 2 to return to the client.
本发明实施例提供的资源节点信息通知方法在实际应用中，如果P2P应用对于资源节点的数量有要求，例如BT下载业务规定，用户端至少需要4个资源节点进行资源的下载（有利于用户端能够完整地下载该资源的所有部分），那么，在上述步骤的基础上，还可以继续执行以下步骤：In practical applications, the resource node information notification method provided by the embodiment of the present invention, if the P2P application has a requirement for the number of resource nodes, such as the BT download business regulation, the user terminal needs at least 4 resource nodes to download resources (beneficial to the user terminal can completely download all parts of the resource), then, on the basis of the above steps, you can also continue to perform the following steps:
步骤S203、将存储的资源节点信息中包含的本网资源节点的数量与设定的阈值比较。当本网资源节点的数量未达到该设定的阈值时，执行下述步骤S204。Step S203, comparing the number of local network resource nodes included in the stored resource node information with a set threshold. When the number of resource nodes on the local network does not reach the set threshold, the following step S204 is performed.
步骤S204、当本网资源节点的数量未达到设定的阈值时，在返回所有的本网资源节点信息之外，还需要在存储的资源节点中的外网资源节点中，按照预设的各个运营商网络的优先级顺序，依次选取足够数量的外网资源节点返回给用户端。Step S204, when the number of resource nodes on the local network does not reach the set threshold, in addition to returning all resource node information on the local network, it is also necessary to store resource nodes in the external network according to each preset According to the priority order of the operator's network, a sufficient number of external network resource nodes are sequentially selected and returned to the client.
补充返回的外网资源节点信息的数量等于阈值与已返回的本网资源节点的数量之差。The number of supplementary returned external network resource node information is equal to the difference between the threshold and the returned number of local network resource nodes.
各个运营商网络的优先级顺序，例如可以依据本网（ISP1网络）与各外网中不同的自治域（Autonomous System，AS）之间的树状订购关系和连接关系来决定，本网与各外网的不同自治域之间的树状订购关系和连接关系决定了本网与各外网之间比特传输代价的大小，可以优先选择与之传输代价较低的外网的资源节点信息返回给用户端。The order of priority of each operator's network, for example, can be determined according to the tree order relationship and connection relationship between the home network (ISP1 network) and different autonomous domains (Autonomous System, AS) in each extranet. The tree order relationship and connection relationship between different autonomous domains of the external network determine the cost of bit transmission between the local network and each external network, and the resource node information of the external network with a lower transmission cost can be preferentially selected and returned to user terminal.
当然，本发明实施例中，外网的优先级顺序也可以由其他因素等来决定。本发明实施例对此不做限定。Certainly, in the embodiment of the present invention, the priority order of the external network may also be determined by other factors and the like. This embodiment of the present invention does not limit this.
下面针对ISP2这种低级骨干运营商网络（例如移动互联网运营商的网络）来说明本发明实施例所提供的资源节点信息通知方法的原理及步骤。在现有技术中，ISP2网络内部不存在能够提供资源节点信息的索引服务器，本发明实施例提供的资源节点信息通知方法在ISP2网络中设置了索引服务器和资源发布服务器，为了与ISP1网络中的索引服务器进行区分，以下以第一索引服务器称呼ISP2网络中的索引服务器。本发明实施例中可以将ISP2网络中的资源发布服务器的功能设置于第一索引服务器中，将两者合设为同一个设备。The principle and steps of the method for notifying resource node information provided by the embodiment of the present invention are described below for a low-level backbone operator network (such as a network of a mobile Internet operator) such as ISP2. In the prior art, there is no index server that can provide resource node information inside the ISP2 network. The resource node information notification method provided by the embodiment of the present invention sets an index server and a resource publishing server in the ISP2 network. In order to communicate with the ISP1 network The index servers are distinguished, and the index servers in the ISP2 network are referred to as the first index server below. In the embodiment of the present invention, the function of the resource publishing server in the ISP2 network can be set in the first index server, and both can be combined into one device.
还是以ISP2网络中的用户端User使用BT业务进行资源下载为例，如图5所示，本发明实施例提供的资源节点信息通知方法，第一索引服务器需要首先完成下述步骤：Still taking the user terminal User in the ISP2 network to use the BT service to download resources as an example, as shown in Figure 5, in the resource node information notification method provided by the embodiment of the present invention, the first index server needs to first complete the following steps:
步骤S501、第一索引服务器从外网的资源发布服务器上获取资源描述文件并解析，解析出资源描述文件所包含的第二索引服务器的地址信息。Step S501, the first index server obtains and parses the resource description file from the resource publishing server on the external network, and parses out the address information of the second index server included in the resource description file.
第一索引服务器向外网中下载量较大的资源发布服务器上获取各种网络资源对应的资源描述文件，对接收的资源描述文件进行解析，解析出该资源描述文件中所包含的第二索引服务器的地址信息。The first index server obtains the resource description files corresponding to various network resources from the resource publishing server with a large amount of downloads in the external network, parses the received resource description files, and parses out the second index contained in the resource description files The address information of the server.
步骤S502、第一索引服务器根据第二索引服务器的地址信息，向对应的第二索引服务器获取该网络资源对应的资源节点信息。Step S502, the first index server acquires resource node information corresponding to the network resource from the corresponding second index server according to the address information of the second index server.
为了与ISP2网络中的第一索引服务器相区别，称位于外网的索引服务器为第二索引服务器。In order to distinguish it from the first index server in the ISP2 network, the index server located on the external network is called the second index server.
步骤S503、第一索引服务器将获取到的资源描述文件中包含的第二索引服务器地址修改为自身的地址。Step S503, the first index server modifies the address of the second index server included in the obtained resource description file to its own address.
步骤S504、第一索引服务器将修改后的资源描述文件发送至本网内的资源发布服务器进行发布。Step S504, the first index server sends the modified resource description file to the resource publishing server in the local network for publishing.
为了实现ISP2网内的用户端User能够直接登录本网内的资源发布服务器，而不通过核心路由器访问外网的资源发布网站，在本发明实施例中，对现有ISP2网络中的域名服务器（Domain Name Server，DNS）预先设置了重定向功能，当用户端向本网的域名服务器发起登录外网资源发布服务器的登录请求时，该域名服务器可以实现将该登录请求重定向至本网的资源发布服务器，这样，对于本网用户端User来说，并不知道自己实际登录的网站服务器是网内的资源服务器。由于DNS的重定向功能属于现有技术的范围，在此不再赘述。In order to realize that the user terminal User in the ISP2 network can directly log in to the resource publishing server in this network, without accessing the resource publishing website of the external network through the core router, in the embodiment of the present invention, the domain name server in the existing ISP2 network ( Domain Name Server (DNS) has pre-set the redirection function. When the client sends a login request to the domain name server of this network to log in to the resource publishing server of the external network, the domain name server can redirect the login request to the resources of this network. In this way, for the user of this network, the user does not know that the website server that he actually logs in is a resource server in the network. Since the redirection function of the DNS belongs to the scope of the prior art, it will not be repeated here.
当ISP2网内资源发布服务器接收到本网用户端User发起的经过重定向后的登录请求，ISP2网内的资源发布服务器向用户端User返回资源发布网页的内容，用户User根据需要选择需要获取的网络资源，也就是向本网的资源发布服务器发送获取资源描述文件的请求，此后第一索引服务器端的流程，如图6所示，包括：When the resource publishing server in the ISP2 network receives the redirected login request initiated by the user of the network, the resource publishing server in the ISP2 network returns the content of the resource publishing webpage to the user, and the user selects the content that needs to be obtained according to the needs. Network resources, that is, send a request to obtain a resource description file to the resource publishing server of this network, and then the process of the first index server, as shown in Figure 6, includes:
步骤S601、本网资源发布服务器接收用户端User发送的获取资源描述文件的请求。In step S601, the resource publishing server of the local network receives a request for obtaining a resource description file sent by a user terminal User.
步骤S602、本网的资源发布服务器向该用户端返回修改后的资源描述文件。Step S602, the resource publishing server of the local network returns the modified resource description file to the client.
步骤S603、用户端获取该资源描述文件并解析，根据修改后的资源描述文件中所包含索引服务器的地址，也就是ISP2网络中第一索引服务器的地址，向第一索引服务器发起资源节点信息获取请求。Step S603, the client obtains and parses the resource description file, and initiates resource node information acquisition to the first index server according to the address of the index server contained in the modified resource description file, that is, the address of the first index server in the ISP2 network ask.
步骤S604、第一索引服务器接收该用户端发起的获取请求，确定出存储的对应资源的资源节点信息中所包含的本网资源节点信息，并根据各本网资源节点所属的子域网的流量负荷参数信息和各本网资源节点的自身服务能力信息，从本网资源节点信息中选取所需返回的资源节点信息，返回给该用户端。Step S604, the first index server receives the acquisition request initiated by the client, determines the resource node information of the local network contained in the resource node information of the corresponding resource stored, and according to the traffic of the sub-domain network to which each resource node of the local network belongs The load parameter information and the self-service capability information of each local network resource node select the resource node information to be returned from the local network resource node information and return it to the client.
与ISP1网络类似，ISP2网络中，可以预先划分为若干个子域网，每个子域网周期性地统计本子域网内的流量总量，计算本子域网流量密度值上报给ISP2网络中的第一索引服务器；同时，各子域网中的节点周期性地统计自身CPU平均使用率、内存平均使用率以及可用网络带宽等参数作为自身服务能力信息上报给第一索引服务器。Similar to the ISP1 network, the ISP2 network can be pre-divided into several sub-area networks, and each sub-area network periodically counts the total amount of traffic in the sub-area network, and the calculated traffic density value of the sub-area network is reported to the first in the ISP2 network. Index server; meanwhile, the nodes in each sub-area network periodically count their average CPU usage, average memory usage, and available network bandwidth and other parameters as their own service capability information and report them to the first index server.
ISP2网络中的第一索引服务器在存储的资源节点信息包含的所有本网资源节点信息中，进一步地参照各本网资源节点所属的子域网上报的流量密度值信息和各本网资源节点上报的自身服务能力信息，选取需要返回的本网资源节点信息，最终将选取出来的本网资源节点信息返回给用户端。具体的选取原则和方法也与前述步骤S202中相同，在此不再详述。The first index server in the ISP2 network further refers to the traffic density value information reported by the sub-domain network to which each resource node of the local network belongs and the resource node information reported by each local network resource node among all the resource node information of the local network contained in the stored resource node information. own service capability information, select the resource node information of the local network that needs to be returned, and finally return the selected resource node information of the local network to the client. The specific selection principles and methods are also the same as those in the aforementioned step S202, and will not be described in detail here.
与ISP1网络中类似，如果P2P应用对于资源节点的数量有要求，那么，在上述步骤的基础上，如图6所示，还可以继续执行以下步骤：Similar to the ISP1 network, if the P2P application has requirements for the number of resource nodes, then, on the basis of the above steps, as shown in Figure 6, the following steps can also be performed:
步骤S605、第一索引服务器将存储的资源节点信息中包含的本网资源节点的数量与设定的阈值比较。Step S605 , the first index server compares the number of local network resource nodes included in the stored resource node information with a set threshold.
当本网资源节点的数量未达到该设定的阈值时，执行下述步骤S606。When the number of resource nodes on the local network does not reach the set threshold, the following step S606 is performed.
步骤S606、当存储的该资源对应的本网资源节点的数量未达到设定的阈值时，第一索引服务器在返回所有的本网资源节点信息之外，在存储的资源节点中的外网资源节点中，按照预设的各个运营商网络的优先级顺序，依次选取足够数量的外网资源节点返回给用户端。Step S606, when the number of resource nodes stored on the local network corresponding to the resource does not reach the set threshold, the first index server returns information on all resource nodes on the local network, and the resource nodes on the external network stored in the resource nodes Among the nodes, according to the preset priority order of each operator's network, a sufficient number of external network resource nodes are sequentially selected and returned to the user terminal.
各个运营商网络的优先级顺序，例如可以依据本网（ISP1网络）与各外网的自治域之间的树状订购关系和连接关系来决定。The order of priority of each operator's network can be determined, for example, according to the tree order relationship and connection relationship between the home network (ISP1 network) and the autonomous domains of each external network.
具体选取的原则和方法与图2中的步骤S204相同，在此不再详述。The principles and methods for specific selection are the same as step S204 in FIG. 2 , and will not be described in detail here.

相应地，确定模块702，还用于根据各子域网流量密度值信息、每个节点自身CPU平均使用率信息、内存平均使用率信息和可用网络带宽信息，从存储的所有本网资源节点信息中选取所需返回的资源节点信息。Correspondingly, the determining module 702 is further configured to select from all the resource node information of the local network stored according to the traffic density value information of each sub-area network, the average CPU usage information of each node itself, the average memory usage information, and the available network bandwidth information.

返回模块703，还用于将确定模块702选取的外网资源节点信息返回至该用户端。The return module 703 is further configured to return the external network resource node information selected by the determination module 702 to the client.
本发明实施例提供的一种资源节点信息通知方法及网络实体装置，在接收本网用户端发起的获取资源节点信息的请求之后，确定出对应资源节点信息中所包含的本网资源节点信息，并返回给用户端。对用户端来说，由于所接收到的资源节点信息可能全部或绝大多数都是本网节点的信息，所以，当用户端与这些资源节点之间建立连接进行资源传输时所产生的流量基本上都发生在本网内部，较大程度地降低了跨网的流量，减轻运营商网络设备的负担和运营成本，避免了由于跨网流量所产生的不同运营商网络之间通信瓶颈问题。The resource node information notification method and the network entity device provided by the embodiments of the present invention determine the resource node information of the local network contained in the corresponding resource node information after receiving a request for acquiring resource node information initiated by a user terminal of the local network, and return to the client. For the client, since all or most of the received resource node information may be the information of the nodes on the local network, the traffic generated when the client establishes a connection with these resource nodes for resource transmission is basically The above-mentioned information happens inside the network, which greatly reduces the cross-network traffic, reduces the burden on the operator's network equipment and operating costs, and avoids the communication bottleneck problem between different operator networks caused by the cross-network traffic.
进一步地，本发明实施例提供的资源节点信息通知方法及网络实体装置，还通过将本网预先划分为若干各子域网，各子域网周期性地上报本子域网流量密度值信息，本网内的每个节点也周期性地上报自身服务能力信息，索引服务器根据各子域网上报的流量密度值信息和各本网节点上报的服务能力信息，在存储的对应资源的本网资源节点信息中，进一步地选取所属流量密度较小、服务能力较高的本网资源节点信息返回给用户端，提高了用户端与本网资源节点间进行数据传输的效率，且降低了P2P数据传输在本网内发生拥塞的可能性。Furthermore, the resource node information notification method and the network entity device provided by the embodiments of the present invention further divide the local network into several sub-area networks, and each sub-area network periodically reports the traffic density value information of the local sub-area network. Each node in the network also periodically reports its own service capability information, and the index server stores corresponding resources in the local network resource node In the information, the resource node information of the local network with low traffic density and high service capability is further selected and returned to the client, which improves the efficiency of data transmission between the client and the resource node of the local network, and reduces the time spent on P2P data transmission. Possibility of congestion within the network.
即使在存储的对应资源的所有本网资源节点的数量未达到设定的阈值，必须向用户端补充返回外网资源节点信息的情况下，本网的索引服务器可以按照各外网的优先级顺序，例如根据网间传输代价从低到高对应的优先级顺序，在存储的对应资源的外网资源节点中尽量选取与本网间传输代价较低的外网的资源节点信息返回给客户端，在尽可能地降低跨网P2P数据传输流量的前提下，进一步优化了跨网进行P2P数据传输的效率和经济性。Even if the number of all local network resource nodes stored for the corresponding resource does not reach the set threshold, and it is necessary to supplement and return external network resource node information to the client, the index server of the local network can follow the priority order of each external network For example, according to the priority sequence corresponding to the transmission cost between the networks from low to high, try to select the resource node information of the external network with a lower transmission cost between the local network from the stored external network resource nodes of the corresponding resources and return it to the client. On the premise of reducing the cross-network P2P data transmission traffic as much as possible, the efficiency and economy of cross-network P2P data transmission are further optimized.
