在IPTV(Internet Protocol Television or Interactive Personal TV)系统中，IPTV直播组播节省了大量的CDN资源和带宽，而OTT直播业务中，目前都以单播形式提供服务。因此，运营商希望将OTT直播与新型组播技术相结合，提供OTT组播能力，以应对OTT直播高并发，大流量的要求，特别是用来应对各种实时直播、网红直播的流量潮汐是非常有效的OTT业务相对于传统IPTV业务来说，有一个不同的特点：OTT内容提供商除了传统的CP(Content Provider内容提供商)外，还存在大量的互联网CP，这些互联网CP对于运营商来说，基本都是非签约的内容提供商用户，他们需要的是运营商的内容分发通道，能随时给最终观众提供服务。对于非签约用户，运营商无法按传统视频业务方式，预先给此类用户分配服务资源及配置调度策略。In IPTV (Internet Protocol Television or Interactive Personal TV) systems, IPTV live broadcast multicast saves a lot of CDN resources and bandwidth, while in OTT live broadcast services, services are currently provided in the form of unicast. Therefore, operators hope to combine OTT live broadcast with new multicast technology to provide OTT multicast capabilities to cope with the high concurrency and large traffic requirements of OTT live broadcast, especially to cope with the traffic tide of various real-time live broadcasts and Internet celebrity live broadcasts. It is a very effective OTT service. Compared with the traditional IPTV service, it has a different characteristic: in addition to the traditional CP (Content Provider content provider), OTT content providers also have a large number of Internet CPs. These Internet CPs are very important to operators. Generally speaking, they are basically non-contracted content provider users. What they need is the operator's content distribution channel, which can provide services to the final audience at any time. For non-subscriber users, operators cannot pre-allocate service resources and configure scheduling strategies to such users according to traditional video service methods.
本发明实施例提供一种非签约内容提供商的服务资源分发方法和视频服务系统，能够降低运营商的流量潮汐冲击效应，减少运维成本，为不同用户提供差异化的业务服务。Embodiments of the present invention provide a service resource distribution method and a video service system for non-contracted content providers, which can reduce the traffic tidal impact effect of operators, reduce operation and maintenance costs, and provide differentiated business services for different users.

步骤S310：调度中心获取来自终端的服务请求，并根据负载均衡调度策略将所述服务请求调度到CDN服务节点；Step S310: The dispatch center obtains the service request from the terminal and dispatches the service request to the CDN service node according to the load balancing scheduling policy;
步骤S320：所述CDN服务节点提供单播服务。Step S320: The CDN service node provides unicast service.
可以理解的是，在满足预设切换条件之前，视频服务系统还是采用单播的方式来提供服务，避免组播资源的浪费。It is understandable that before the preset switching conditions are met, the video service system still uses unicast to provide services to avoid wasting multicast resources.
在上述的服务资源分发方法中，还包括：当所述终端启动所述组播代理，所述组播代理向所述组播业务管理平台进行认证注册。In the above service resource distribution method, the method further includes: when the terminal starts the multicast agent, the multicast agent performs authentication and registration with the multicast service management platform.
需要说明的是，组播代理向组播业务管理平台进行认证注册，以保证组播代理的合法性，注册成功后，组播代理再加入组播频道的组播组。It should be noted that the multicast agent performs authentication and registration with the multicast service management platform to ensure the legitimacy of the multicast agent. After successful registration, the multicast agent joins the multicast group of the multicast channel.

可以理解的是，组播代理加入组播组后，会将终端的BFER信息上报给组播业务管理平台，组播业务管理平台给BIER控制器同步该BFER信息，告诉BIER控制器有新的终端用户需要加入BIER网络的分发链路中，从而更新BIER网络的分发链路以及更新组播频道、BFIR、BFER的映射关系，使得新加入BIER网络的终端用户能够正常获取到组播媒体流。It can be understood that after the multicast agent joins the multicast group, it will report the BFER information of the terminal to the multicast service management platform. The multicast service management platform will synchronize the BFER information to the BIER controller and tell the BIER controller that there is a new terminal. Users need to join the distribution link of the BIER network to update the distribution link of the BIER network and update the mapping relationship between multicast channels, BFIR, and BFER, so that terminal users who newly join the BIER network can obtain multicast media streams normally.

步骤S720：当所述组播媒体流的帧与所述单播媒体流的帧完全同步，所述组播代理发送停止单播通知至终端，以使所述终端停止从所述CDN服务节点获取单播媒体流。Step S720: When the frames of the multicast media stream are completely synchronized with the frames of the unicast media stream, the multicast agent sends a stop unicast notification to the terminal so that the terminal stops obtaining data from the CDN service node. Unicast media streaming.
在上述的服务资源分发方法中，还可以包括：The above service resource distribution method may also include:
所述组播代理响应于所述终端的组播服务请求，将所述组播媒体流转成单播媒体流并发送给所述终端进行解码播放。In response to the multicast service request of the terminal, the multicast agent converts the multicast media stream into a unicast media stream and sends it to the terminal for decoding and playback.
在上述的服务资源分发方法中，所述组播服务器从所述CDN服务节点获取单播媒体流，包括以下两种方式之一：In the above service resource distribution method, the multicast server obtains the unicast media stream from the CDN service node, including one of the following two methods:
所述组播服务器到所述CDN服务节点进行单播媒体流的拉流；The multicast server pulls the unicast media stream to the CDN service node;
所述CDN服务节点向所述组播服务器进行单播媒体流的推流。The CDN service node pushes the unicast media stream to the multicast server.
在上述的服务资源分发方法中，所述服务信息包括用户量、带宽占用量、带宽变化趋势中的至少之一；所述预设切换条件相应包括以下至少之一：In the above service resource distribution method, the service information includes at least one of the number of users, bandwidth occupancy, and bandwidth change trend; the preset switching condition correspondingly includes at least one of the following:
所述用户量大于第一预设值；The number of users is greater than the first preset value;
所述带宽占用量大于第二预设值；The bandwidth occupancy is greater than the second preset value;
所述带宽占用率在预设时长内持续上升。The bandwidth occupancy rate continues to increase within a preset time period.
可以理解的是，当用户量大于第一预设值，也即具有一定数量的终端通过单播的方式获得服务，消耗了大量的CDN资源的网络带宽，容易引起潮汐现象，严重影响运营商的日常运行及成本；同理，当带宽占用量大于第二预设值，也容易引起潮汐现象，因此需要从单播服务切换成组播服务，降低运营商的流量潮汐冲击效应，减少运维成本，为不同用户提供差异化的业务服务；同理，带宽占用率在预设时长内持续上升，说明可能已经引起潮汐现象，因此需要从单播服务切换成组播服务，降低运营商的流量潮汐冲击效应。It can be understood that when the number of users is greater than the first preset value, that is, a certain number of terminals obtain services through unicast, a large amount of network bandwidth of CDN resources is consumed, which is likely to cause a tidal phenomenon and seriously affect the operator's performance. Daily operation and cost; similarly, when the bandwidth usage is greater than the second preset value, it is easy to cause a tidal phenomenon, so it is necessary to switch from unicast service to multicast service to reduce the operator's traffic tidal impact effect and reduce operation and maintenance costs. , to provide differentiated business services for different users; similarly, the bandwidth occupancy continues to rise within the preset time period, indicating that a tidal phenomenon may have been caused, so it is necessary to switch from unicast service to multicast service to reduce the operator's traffic tide shock effect.

可以理解的是，BFIR(Bit Index Explicit Replication，位索引显式复制)技术，提供了一种无状态的组播转发机制，在组播首节点BIER(器Bit-Forward Ingress Router，入口路由)根据组播的接收者BFER(Bit-Forward Egress Router，出口路由器)信息生成转发BS(BitString串)，根据BS的位运算进行分发，而中间节点BFR(Bit-Forward Router，转发路由器)不需要维护任何组播流转发状态信息(Group、Ingress、Egress)，BIER链路状态库则由IGP(ISIS/OSPF)协议的BIER扩展洪泛生成。It can be understood that BFIR (Bit Index Explicit Replication, Bit Index Explicit Replication) technology provides a stateless multicast forwarding mechanism. According to the multicast first node BIER (Bit-Forward Ingress Router, ingress routing) The multicast receiver BFER (Bit-Forward Egress Router, egress router) information generates a forwarding BS (BitString string), which is distributed according to the bit operation of the BS, while the intermediate node BFR (Bit-Forward Router, forwarding router) does not need to maintain any The multicast flow forwarding status information (Group, Ingress, Egress), and the BIER link status library are generated by the BIER extension flooding of the IGP (ISIS/OSPF) protocol.
本发明实施例提供的是基于Bier技术的非签约场景下的通过集中式组播的方式来提供视频服务。在非签约CP下，为了便于统一管理，减少客户端的资源消耗，由服务端对组播分发的时机和策略进行集中式统一管理：Embodiments of the present invention provide video services through centralized multicast in a non-subscription scenario based on Bier technology. Under non-signed CP, in order to facilitate unified management and reduce resource consumption on the client, the server performs centralized unified management of the timing and strategy of multicast distribution:
1)对用户的播放请求，通过分光器DPI(Deep Packet Inspection，深度报文检测)劫持业务请求，镜像至组播业务管理平台，组播业务管理平台根据预设过滤策略(比如根据CPID、业务类型、用户请求协议类型等)进行业务分析以及统计热点内容信息，然后根据预设切换策略(比如用户量、带宽占用量、带宽变化趋势等)进行判断是否进行单组播切换。1) For the user's playback request, the service request is hijacked through the optical splitter DPI (Deep Packet Inspection, Deep Packet Inspection) and mirrored to the multicast service management platform. The multicast service management platform based on the preset filtering policy (for example, based on CPID, service type, user request protocol type, etc.) to conduct business analysis and collect statistics on hot content information, and then determine whether to perform single-multicast switching based on the preset switching strategy (such as user volume, bandwidth usage, bandwidth change trend, etc.).
2)当达到单组播切换的预设切换条件时，组播业务系统一方面通过通知客户端进行单组播拉流切换，另一方面与BIER控制器进行交互，将此用户对应的BFER信息同步给BIER控制器，BIER控制器通知BFIR更新BS(BitString)串并刷新分发链路信息，组播服务器将单播媒体流转成组播媒体流推送给BFIR。2) When the preset switching conditions for single-multicast switching are reached, the multicast service system notifies the client to perform single-multicast streaming switching on the one hand, and interacts with the BIER controller on the other hand to obtain the BFER information corresponding to the user. Synchronized to the BIER controller, the BIER controller notifies the BFIR to update the BS (BitString) series and refresh the distribution link information, and the multicast server converts the unicast media stream into a multicast media stream and pushes it to the BFIR.
3)BFIR收到组播媒体流后，根据BS串值在BIER网络中进行转发；3) After receiving the multicast media stream, BFIR forwards it in the BIER network according to the BS string value;
4)终端加入到本CP的组播频道的组播组，到BFER拉取组播媒体流，并通过组播代理转成单播媒体流，终端进行解码播放。4) The terminal joins the multicast group of the multicast channel of this CP, pulls the multicast media stream from the BFER, and converts it into a unicast media stream through the multicast agent, and the terminal decodes and plays it.
运营商在现有视频服务系统中，只需要将网络中的相关路由器设备进行协议升级以支持Bier技术，服务端新部署组播业务管理平台和组播服务器，终端中安装组播代理即可实现，成本低，易管理。In the existing video service system, operators only need to upgrade the relevant router equipment in the network to support Bier technology, deploy a new multicast service management platform and multicast server on the server, and install a multicast agent in the terminal. , low cost and easy to manage.
本发明实施例提供的服务资源分发方法，可以应用非签约CP场景下的新型的互联网大流量直播业务，如网红直播、会议直播、带货直播等。对大量的互联网的非签约直播CP场景下，因其随时随地的偶发性业务特性及大用户量的并发请求，会对运营商网络的流量带来非常大的冲击，潮汐现象非常明显。为减少新型直播业务对现网业务和网络的影响，将现有单播分发优化为单播和组播相结合的方式，根据用户量的实时情况，视频服务系统自动决策单播还是组播，同时基于Bier技术的组播分发可以让应用与传输完全解耦，做到真正的网络层的组播转发，而不需要关注其业务特性，进一步减少组播维护与管理的成本，提高组播分发效率，所以本发明实施例的方案在非签约CP的场景，提供集中式组播能力，可以获得非常高效稳定的组播分发性能，并保障大运营商引入互联网大流量业务，有效降低运维成本，拓宽运营商的视频业务范围，为不同用户提供差异化的业务服务，增加新的营收，同时又可以节省大流量用户的运营成本，提升用户的满意度。The service resource distribution method provided by the embodiment of the present invention can be applied to new Internet high-traffic live broadcast services in non-contracted CP scenarios, such as Internet celebrity live broadcasts, conference live broadcasts, product live broadcasts, etc. In the scenario of a large number of non-contracted live broadcast CPs on the Internet, due to the sporadic business characteristics anytime and anywhere and the large number of concurrent requests from users, it will have a very large impact on the traffic of the operator's network, and the tidal phenomenon is very obvious. In order to reduce the impact of new live broadcast services on existing network services and networks, existing unicast distribution is optimized to a combination of unicast and multicast. Based on the real-time situation of user volume, the video service system automatically decides whether to use unicast or multicast. At the same time, multicast distribution based on Bier technology can completely decouple applications and transmission, achieving true multicast forwarding at the network layer without paying attention to its business characteristics, further reducing the cost of multicast maintenance and management, and improving multicast distribution. Efficiency, so the solution of the embodiment of the present invention provides centralized multicast capabilities in non-contracted CP scenarios, can obtain very efficient and stable multicast distribution performance, and ensures that large operators can introduce Internet high-traffic services, effectively reducing operation and maintenance costs. , broaden the operator's video business scope, provide differentiated business services for different users, increase new revenue, and at the same time save the operating costs of high-traffic users and improve user satisfaction.
