本发明涉及云平台技术领域。本发明进一步涉及一种云平台路由管理的方法及装置。The invention relates to the field of cloud platform technology. The present invention further relates to a method and device for cloud platform routing management.
背景技术Background technique
随着网络规模的不断扩大和网络复杂度的提高，计算机的数量经常超过可供分配的IP地址数量。同时计算机的位置也经常变化，相应的IP地址也必须经常更新，从而导致网络配置越来越复杂。DHCP(Dynamic Host Configuration Protocol，动态主机配置协议)就是为解决这些问题而发展起来的。With the continuous expansion of network scale and the improvement of network complexity, the number of computers often exceeds the number of IP addresses available for allocation. At the same time, the location of the computer changes frequently, and the corresponding IP address must also be updated frequently, which makes the network configuration more and more complicated. DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) was developed to solve these problems.
DHCP可以提供三种IP地址分配策略。而在FPGA云平台软件的设计中，是采用动态分配IP的方式为网络中所连接的所有FPGA板卡分配IP 地址。因此在当前的FPGA云平台的设计中，会经常遇到IP地址因为各种原因发生变化的情况，例如由于新加入FPGA板卡、更换FPGA板卡、交换机开关机等原因。DHCP can provide three IP address allocation strategies. In the design of FPGA cloud platform software, IP addresses are allocated to all FPGA boards connected in the network by means of dynamic IP allocation. Therefore, in the design of the current FPGA cloud platform, it is often encountered that the IP address changes due to various reasons, such as the addition of new FPGA boards, replacement of FPGA boards, switching on and off of switches, and so on.
当前的FPGA云平台软件中，通过Wireshark抓包软件获得IP信息后，手工记录下所有已有的FPGA板卡IP和MAC，同时修改软件中对应的路由表，继而通过发送帧数据包通知所有网络中FPGA板卡路由表信息。In the current FPGA cloud platform software, after obtaining IP information through Wireshark packet capture software, manually record all existing FPGA board IP and MAC, modify the corresponding routing table in the software, and then notify all networks by sending frame data packets In the FPGA board routing table information.
当前FPGA云平台的设计中，鉴于路由表会经常发生变化，每次都需要参考网络抓包软件(如Wireshark)里面的IP信息手动更新路由表，然后再下发指令通知FPGA其路由表即MAC和IP信息，这样操作的缺点包括以下几个方面：In the current design of the FPGA cloud platform, in view of the frequent changes in the routing table, it is necessary to manually update the routing table with reference to the IP information in the network packet capture software (such as Wireshark) each time, and then issue instructions to notify the FPGA of its routing table, which is the MAC address. and IP information, the disadvantages of this operation include the following aspects:
1)信息捕捉丢失：网络监控抓包软件可能会因为延迟等因素捕捉不到某些板卡的IP。1) Loss of information capture: The network monitoring packet capture software may fail to capture the IP of some boards due to factors such as delay.
2)人工核对出错率较高：由于数字量比较大，每次手动更新软件IP 和MAC表格可能会核对出错，尤其是网络中FPGA板卡较多的情况下尤为突出。2) The error rate of manual verification is high: Due to the relatively large number of numbers, each manual update of the software IP and MAC tables may cause verification errors, especially when there are many FPGA boards in the network.
3)耗时：每次IP更新后，需要耗费时间去重新修改路由表，并且编译。3) Time-consuming: After each IP update, it takes time to re-modify the routing table and compile it.
因此，为了解决上述问题，需要提出一种优化的云平台路由管理的方法使得所有的IP及MAC的获取及配置能够及时、准确、自动地实现。Therefore, in order to solve the above problems, it is necessary to propose an optimized cloud platform routing management method so that the acquisition and configuration of all IPs and MACs can be realized in a timely, accurate and automatic manner.

图1示出了根据本发明的云平台路由管理的方法的实施例的示意性框图。在如图所示的实施例中，该方法至少包括以下步骤：Fig. 1 shows a schematic block diagram of an embodiment of a method for cloud platform routing management according to the present invention. In the embodiment shown in the figure, the method at least includes the following steps:
S1：解析DHCP租约数据库中所有租约信息以形成租约列表；S1: Parse all lease information in the DHCP lease database to form a lease list;
S2：将租约列表的各行按MAC地址进行分组，并为各MAC地址确定所分配的当前IP地址；S2: group each row of the lease list by MAC address, and determine the current IP address allocated for each MAC address;
S3：根据各MAC地址及所分配的当前IP地址的对应关系生成路由表，并将该路由表下发给云平台中的各板卡；S3: Generate a routing table according to the corresponding relationship between each MAC address and the assigned current IP address, and send the routing table to each board in the cloud platform;
S4：各板卡分别根据其MAC地址查询路由表以确定所分配的当前IP地址。S4: Each board checks the routing table according to its MAC address to determine the current IP address allocated.
为了解决利用抓包软件可能无法捕捉IP信息、人工核对出错率高、每次IP更新后重新修改路由表耗时耗力等问题，根据本发明提出了充分利用DHCP租约数据库的构思，解析其中的数据信息并进行整合提取，从而进一步生成所需的路由表，并下发给板卡以通知各板卡其被分配的IP 地址。In order to solve the problems that the use of packet capture software may not be able to capture IP information, the manual check error rate is high, and the routing table is time-consuming and labor-intensive after each IP update, according to the present invention, the concept of making full use of the DHCP lease database is proposed, and the analysis of the The data information is integrated and extracted, so as to further generate the required routing table, and send it to the board to notify each board of its assigned IP address.
具体地，首先步骤S1解析DHCP租约数据库中所有租约信息以形成租约列表。由于DHCP租约数据库中的租约信息通常以一定的格式记录在DHCP客户租约的数据库文件(LINUX下dhcpd.leases是DHCP客户机租约的数据库文件，默认目录在/var/lib/dhcp/，文件包含租约声明)中。所以按照一定的格式解析DHCP租约数据库中的租约信息，并将每一条租约信息解析出来的元素按行生成租约列表。Specifically, first step S1 parses all lease information in the DHCP lease database to form a lease list. Because the lease information in the DHCP lease database is usually recorded in the database file of the DHCP client lease in a certain format (dhcpd. statement). Therefore, the lease information in the DHCP lease database is parsed according to a certain format, and the elements of each piece of lease information are parsed to generate a lease list by row.
每次一个租约被获取、更新或者释放，相应的信息就会重新被记录到该租约文件中。也就是说，DHCP租约数据库记录了所有租约信息，包括历史上曾经有效的以及当前有效的租约信息。所以在整个文件中，对于同一个MAC，可能会查看到多个IP的记录。而实际上对固定的MAC(即 FPGA板卡)，当前有效的IP地址只有一个。因此，需要进一步确定哪个IP地址才是当前有效的IP地址。为此，步骤S2将租约列表的各行按 MAC地址进行分组，并为各MAC地址确定所分配的当前IP地址。然后，步骤S3根据各MAC地址及所分配的当前IP地址的对应关系生成路由表，并将该路由表下发给云平台中的各板卡。Every time a lease is acquired, renewed, or released, the corresponding information will be re-recorded in the lease file. That is to say, the DHCP lease database records all lease information, including historically valid and currently valid lease information. Therefore, in the entire file, for the same MAC, multiple IP records may be viewed. In fact, there is only one valid IP address for a fixed MAC (that is, FPGA board). Therefore, it is necessary to further determine which IP address is the currently valid IP address. To this end, step S2 groups the rows of the lease list by MAC address and determines for each MAC address the current IP address assigned. Then, step S3 generates a routing table according to the corresponding relationship between each MAC address and the assigned current IP address, and sends the routing table to each board in the cloud platform.
云平台中在线的板卡在被通知了最新的路由表之后，它们就可以据此获悉分配给它们的当前IP地址，即步骤S4各板卡分别根据其自身的MAC 地址查询路由表以确定所分配的当前IP地址。在得到了当前分配给相应板卡的IP地址后，该板卡就可以进行正常的网络进程。After the online boards in the cloud platform are notified of the latest routing table, they can learn the current IP address assigned to them accordingly, that is, each board in step S4 queries the routing table according to its own MAC address to determine the IP address assigned to it. The current IP address assigned. After obtaining the IP address currently assigned to the corresponding board, the board can perform normal network processes.
下文将说明本发明的进一步实施例，需要注意的是，其中提到的步骤的编号在没有特殊说明的情况下，仅用于便捷明确地指示该步骤，并不限定所述步骤的顺序。Further embodiments of the present invention will be described below. It should be noted that the numbers of the steps mentioned therein are only used for convenient and clear indication of the steps unless otherwise specified, and do not limit the sequence of the steps.
在本发明的云平台路由管理的方法的一个或多个实施例中，租约列表的各行至少包括相对应的IP地址、占用时间、MAC地址。步骤S1中生成的租约列表基于解析DHCP租约数据库中所有租约信息形成。其中，按照一定的格式解析DHCP租约数据库中的租约信息，并将每一条租约信息解析出来的元素按行生成租约列表，而每行中的解析出的元素至少包括IP地址、占用时间、MAC地址。虽然DHCP租约数据库中的租约信息会包含获取、释放时间等多个时间信息，但是由于每一个MAC地址只会占用一个IP地址，并且每一个IP地址只会被一个MAC地址所占用。因此，租约列表中的占用时间优选地为获取时间。In one or more embodiments of the cloud platform routing management method of the present invention, each line of the lease list includes at least a corresponding IP address, occupied time, and MAC address. The lease list generated in step S1 is formed based on parsing all lease information in the DHCP lease database. Among them, the lease information in the DHCP lease database is parsed according to a certain format, and the elements parsed from each piece of lease information are generated into a lease list by row, and the parsed elements in each row include at least IP address, occupied time, and MAC address . Although the lease information in the DHCP lease database will contain multiple time information such as acquisition and release times, each MAC address will only occupy one IP address, and each IP address will only be occupied by one MAC address. Therefore, the occupation time in the lease list is preferably the acquisition time.
在本发明的云平台路由管理的方法的若干实施例中，步骤S2将租约列表的各行按MAC地址进行分组，并为各MAC地址确定所分配的当前 IP地址进一步包括：In some embodiments of the method for cloud platform routing management of the present invention, step S2 groups each row of the lease list by MAC address, and determines that the assigned current IP address for each MAC address further includes:
S21：将所有MAC地址相同的租约列表行分为一组，并在每组中按占用时间先后进行排序；S21: Divide all the lease list rows with the same MAC address into one group, and sort each group according to the occupation time;
S22：以占用时间最新的IP地址作为该组的MAC地址的当前IP 地址。S22: Use the IP address with the latest occupation time as the current IP address of the MAC address of the group.
为了进一步准确地为各MAC从相应所有的IP地址中确定当前有效的IP地址，在这些实施例中，步骤S2租约列表的各行按MAC地址进行分组，并为各MAC地址确定所分配的当前IP地址进一步包括两个步骤，首先步骤S21将所有MAC地址相同的租约列表行分为一组，并在每组的租约列表行中按占用时间先后进行排序。也就是说将包含同一个MAC地址的租约列表行归为同一组，并将各租约列表行按占用时间进行排序，其中优选地占用时间早的在前、占用时间晚的在后。随后，步骤S22以占用时间最新的IP地址作为该组的MAC地址的当前IP地址，优选地在S21 中按占用时间早的在前、占用时间晚的在后进行排序的情况下以每组中处于末位的租约列表行中的IP地址作为该组的MAC地址的当前IP地址，并为两者建立对应关系。In order to further accurately determine the current effective IP address from all corresponding IP addresses for each MAC, in these embodiments, each row of the lease list in step S2 is grouped by MAC address, and the assigned current IP address is determined for each MAC address. The address further includes two steps. First, step S21 divides all lease list lines with the same MAC address into one group, and sorts the lease list lines of each group according to the occupation time. That is to say, the lease list rows containing the same MAC address are grouped into the same group, and the lease list rows are sorted according to the occupation time, wherein preferably the occupation time is earlier and the occupation time is later. Subsequently, step S22 takes the latest IP address of the occupation time as the current IP address of the MAC address of the group, preferably in S21, in the case of sorting by the earlier occupation time and the later occupation time in each group The IP address in the last row of the lease list is used as the current IP address of the group's MAC address, and a corresponding relationship is established between the two.
在本发明的云平台路由管理的方法的一些实施例中，步骤S3根据各 MAC地址及所分配的当前IP地址的对应关系生成路由表，并将路由表下发给云平台中的各板卡进一步包括：In some embodiments of the method for cloud platform routing management of the present invention, step S3 generates a routing table according to the corresponding relationship between each MAC address and the assigned current IP address, and sends the routing table to each board in the cloud platform Further includes:
S31：检查云平台中在线的所有板卡的MAC地址；S31: Check the MAC addresses of all online boards in the cloud platform;
S32：将所有在线板卡的MAC地址及所分配的当前IP地址的对应关系生成路由表。S32: Generate a routing table for the corresponding relationship between the MAC addresses of all online boards and the assigned current IP addresses.
由于DHCP租约数据库记录了所有租约信息，包括历史上曾经有效的以及当前有效的租约信息，因此，其中的租约信息通常包含了遗留的租约信息，这些租约信息中记录的MAC地址对应的板卡并不在线。若将根据这些遗留的租约信息产生的MAC地址及所分配的当前IP地址的对应关系都记录在路由表中会造成不必要的资源浪费，包括对路由表数据量、网络传输链路占用等一系列的非必要负担。因此步骤S3根据各MAC地址及所分配的当前IP地址的对应关系生成路由表时进一步包括两个步骤。首先步骤S31检查云平台中在线的所有板卡的MAC地址，从而确定有必要在路由表中记录的MAC地址及所分配的当前IP地址的对应关系的板卡，剔除遗留的租约信息产生的MAC地址及所分配的当前IP地址的对应关系。随后，步骤S32将所有在线板卡的MAC地址及所分配的当前IP 地址的对应关系生成路由表。这样生成的路由表资源占用最优，即在保证其准确功能的情况下数据量最小、网络传输效率最高。Since the DHCP lease database records all lease information, including historically valid and currently valid lease information, the lease information usually includes legacy lease information, and the boards corresponding to the MAC addresses recorded in the lease information are not not online. If the corresponding relationship between the MAC address generated according to these legacy lease information and the assigned current IP address is recorded in the routing table, it will cause unnecessary waste of resources, including the amount of data in the routing table and the occupation of network transmission links. Series of non-essential burdens. Therefore, step S3 further includes two steps when generating the routing table according to the corresponding relationship between each MAC address and the assigned current IP address. First step S31 checks the MAC addresses of all boards online in the cloud platform, thereby determining the boards that need to be recorded in the routing table and the corresponding relationship between the MAC address and the assigned current IP address, and remove the MAC address generated by the leftover lease information The corresponding relationship between the address and the assigned current IP address. Subsequently, step S32 generates a routing table for the corresponding relationship between the MAC addresses of all online boards and the assigned current IP addresses. The resource occupancy of the routing table generated in this way is optimal, that is, the amount of data is the smallest and the network transmission efficiency is the highest under the condition of ensuring its accurate function.
在本发明的云平台路由管理的方法的进一步实施例中，步骤S3根据各MAC地址及所分配的当前IP地址的对应关系生成路由表，并将路由表下发给云平台中的各板卡进一步包括：通过预定的帧格式将路由表下发给云平台中的各板卡。为了能够不会过多占用网络带宽，在通知板卡路由表时，通过预定的帧格式将路由表中包含的信息下发给所有的板卡。例如，以“MAC地址_IP地址”的格式。In a further embodiment of the method for cloud platform routing management of the present invention, step S3 generates a routing table according to the corresponding relationship between each MAC address and the assigned current IP address, and sends the routing table to each board in the cloud platform It further includes: sending the routing table to each board in the cloud platform through a predetermined frame format. In order not to occupy too much network bandwidth, when the board routing table is notified, the information contained in the routing table is sent to all boards through a predetermined frame format. For example, in the format "MAC address_IP address".
另一方面，本发明还提出了一种云平台路由管理的装置，其中该装置包括：至少一个处理器；和存储器，该存储器存储有处理器可运行的程序指令，该程序指令在被处理器运行时至少执行以下步骤：On the other hand, the present invention also proposes a device for cloud platform routing management, wherein the device includes: at least one processor; and a memory, the memory stores program instructions executable by the processor, and the program instructions are executed by the processor Runtime performs at least the following steps:
