Description

一种管理组播节目的方法、装置和网络设备Method, device and network device for managing multicast programs

技术领域Technical field

本申请涉及通信领域，并且更具体地，涉及一种管理组播节目的方法、装置和网络设备。The present application relates to the field of communications and, more particularly, to a method, apparatus, and network device for managing multicast programs.

背景技术Background technique

网络协议电视(Internet Protocol Television，IPTV)直播节目(组播视频)在网络业务质量(Quality of Service，QoS)规划中，一般都是规划只有一个QoS优先级(例如直播节目的二层802.1p的优先级都为4)，进入网络设备的同一个优先级队列，在队列拥塞发送丢弃的时候，所有节目会无差别丢包，导致所有直播节目同时花屏，影响范围广泛。Internet Protocol Television (IPTV) live broadcast (multicast video) in the network quality of service (QoS) planning, generally planning only one QoS priority (such as the second layer 802.1p of the live program) The priority is 4), and the same priority queue of the network device is entered. When the queue congestion is sent and discarded, all programs will be lost without any difference, resulting in all live programs being screened at the same time, and the impact is wide.

端口带宽接入管理控制(Call Admission Control，CAC)方案(以无源光接入***(Gigabit-Capable PON，GPON)为例)，首先为每一个预配置节目配置带宽，然后为每一个GPON端口分配可用的组播带宽，当设备收到节目的第一个网络组管理协议(Internet Group Management Protocol，IGMP)加入报文，就会从该GPON端口的剩余带宽减掉相应节目的所占带宽。如果余数小于0则拒绝该用户的点播请求。如果收到一个IGMP离开报文，就可以归还相应节目的带宽给该GPON端口(归还的时刻是在停止转发组播数据时，即该GPON端口下没有任何组播用户需要该节目)。Port Admission Control (CAC) scheme (taking Gigabit-Capable PON (GPON) as an example), first configuring bandwidth for each pre-configured program, and then for each GPON port. When the available multicast bandwidth is allocated, when the device receives the first Internet Group Management Protocol (IGMP) join message of the program, the occupied bandwidth of the corresponding program is subtracted from the remaining bandwidth of the GPON port. If the remainder is less than 0, the user's on-demand request is rejected. If an IGMP Leave message is received, the bandwidth of the corresponding program can be returned to the GPON port (the time of return is when the forwarding of the multicast data is stopped, that is, no multicast user needs the program under the GPON port).

该端口带宽CAC方案无法保证重要的节目可点播，组播节目带宽存在突发和码率调整的可能，会导致组播节目可能和实际的带宽不一致，并且，当用户点播的组播节目超过端口CAC带宽，该组播节目不被允许点播，会造成组播节目黑屏的现象。The port bandwidth CAC solution cannot guarantee that important programs can be on-demand, and the multicast program bandwidth may have burst and bit rate adjustment, which may cause the multicast program to be inconsistent with the actual bandwidth, and when the user-on-demand multicast program exceeds the port. The CAC bandwidth, the multicast program is not allowed to be on-demand, which may cause a black screen of the multicast program.

图2示出了根据本申请实施例的管理组播节目的方法100的示意性流程图，该管理组播节目的方法100的执行主体可以为网络设备，如图2所示，该方法100包括：FIG. 2 is a schematic flowchart of a method 100 for managing a multicast program according to an embodiment of the present application. The execution body of the method 100 for managing a multicast program may be a network device. As shown in FIG. 2, the method 100 includes :

S110，接收N个组播节目，该N个组播节目的业务质量Qos优先级相同，N为正整数。S110. Receive N multicast programs, where the service quality Qos priorities of the N multicast programs are the same, and N is a positive integer.

具体而言，网络设备接收N个组播节目，该N个组播节目的业务质量Qos优先级相同，即该N个组播节目携带的报文优先级相同，例如，该N个组播节目的二层802.1p的优先级都为4。Specifically, the network device receives N multicast programs, and the service quality Qos of the N multicast programs have the same priority, that is, the packets carried by the N multicast programs have the same priority, for example, the N multicast programs. The second layer of 802.1p has a priority of 4.

可选地，该N个组播节目都具有802.1p的优先级4，该同一Qos优先级队列为Qos优先级队列4。Optionally, the N multicast programs all have an 802.1p priority level 4, and the same QoS priority queue is a Qos priority queue 4.

应理解，802.1p中定义的优先级有8种。最高优先级为7，应用于关键性网络流量，如路由选择信息协议(RIP)和开放最短路径优先(OSPF)协议的路由表更新。优先级6和5主要用于延迟敏感(delay-sensitive)应用程序，如交互式视频和语音。优先级4到1主要用于受控负载(controlled-load)应用程序，如流式多媒体(streaming multimedia)和关键性业务流量(business-critical traffic)。优先级0是缺省值，并在没有设置其它优先级值的情况下自动启用，其中，优先级4推荐由视频会议和视频流使用。 It should be understood that there are eight priorities defined in 802.1p. The highest priority is 7, which is applied to critical network traffic such as routing table updates for Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) protocols. Priority 6 and 5 are primarily used for delay-sensitive applications such as interactive video and voice. Priority 4 to 1 is primarily used for controlled-load applications such as streaming multimedia and business-critical traffic. Priority 0 is the default and is automatically enabled if no other priority values are set, where priority 4 is recommended for use by video conferencing and video streaming.

可选地，该N个组播节目中每个组播节目携带的报文优先级相同。Optionally, the packets carried by each multicast program in the N multicast programs have the same priority.

S120，对该N个组播节目中每个组播节目配置丢弃优先级。S120. Configure a drop priority for each multicast program in the N multicast programs.

图3示出了根据本申请实施例的管理组播节目的方法100的另一示意性流程图，如图3所示，该对N个组播节目中每个组播节目配置丢弃优先级，包括：FIG. 3 is another schematic flowchart of a method 100 for managing a multicast program according to an embodiment of the present application. As shown in FIG. 3, each multicast program of the pair of N multicast programs is configured with a drop priority. include:

S121，根据预定义分类信息，配置该N个组播节目中每个组播节目的丢弃优先级。S121. Configure, according to the predefined classification information, a discarding priority of each multicast program in the N multicast programs.

具体而言，网络设备接收组播节目的时候，同时配置组播节目的丢弃优先级，该丢弃优先级不依赖于组播节目报文所携带的报文优先级，在网络设备内部转发进入队列的时候使用。Specifically, when the network device receives the multicast program, the network device discards the discarding priority of the multicast program. The discarding priority does not depend on the packet priority of the multicast program packet, and is forwarded to the queue within the network device. Used when.

可选地，该丢弃优先级的个数取决于优先级队列的早丢弃门限的个数，优先级队列的早丢弃门限个数由网络设备本身的硬件条件决定。Optionally, the number of the discarding priorities depends on the number of early discard thresholds of the priority queue. The number of early discard thresholds of the priority queue is determined by hardware conditions of the network device itself.

应理解，该N个组播节目中每个组播节目的丢弃优先级对应于该同一Qos优先级队列的一个早丢弃门限，该每个组播节目的丢弃优先级不完全相同。It should be understood that the discarding priority of each multicast program in the N multicast programs corresponds to an early discarding threshold of the same QoS priority queue, and the discarding priorities of each multicast program are not completely the same.

还应理解，丢弃优先级为交换机(或其他网络设备)在丢弃报文时的参考优先级，其对应于出端口队列，默认情况下即队列调度采用严格丢弃优先级时，拥塞发生时优先级越低越优先丢弃。It should also be understood that the discarding priority is the reference priority of the switch (or other network device) when it discards the packet, which corresponds to the outbound port queue. By default, when the queue scheduling adopts the strict discarding priority, the congestion occurs when the priority occurs. The lower the priority, the higher the priority.

例如，优先级队列4具有3个早丢弃门限，该3个早丢弃门限分别为低优先级丢弃门限、中优先级丢弃门限和高优先级丢弃门限，该网络设备收到3个组播节目(组播节目1、组播节目2和组播节目3)，可以对该组播节目1配置高丢弃优先级，对组播节目2配置中丢弃优先级，对组播节目3配置低丢弃优先级。当组播队列发生拥塞时，优先丢弃配置了低丢弃优先级的组播节目3，以保证配置了中丢弃优先级的组播节目2和配置了高丢弃优先级的组播节目1的质量；或者，当组播节目发生拥塞时，优先丢弃配置了低丢弃优先级的组播节目3和配置了中丢弃优先级的组播节目2，以保证配置了高丢弃优先级的组播节目1的质量。For example, the priority queue 4 has three early discarding thresholds, and the three early discarding thresholds are a low priority discarding threshold, a medium priority discarding threshold, and a high priority discarding threshold, and the network device receives three multicast programs ( Multicast program 1, multicast program 2, and multicast program 3), the multicast program 1 can be configured with a high discarding priority, the multicast program 2 is configured with a discarding priority, and the multicast program 3 is configured with a low discarding priority. . When the multicast queue is congested, the multicast program 3 with the low drop priority is preferentially discarded, so that the quality of the multicast program 2 with the drop priority and the multicast program 1 with the high drop priority are configured. Or, when the multicast program is congested, the multicast program 3 configured with the low drop priority and the multicast program 2 configured with the drop priority are preferentially discarded to ensure that the multicast program 1 with the high drop priority is configured. quality.

又例如，优先级队列4具有3个早丢弃门限，该3个早丢弃门限分别为低优先级丢弃门限、中优先级丢弃门限和高优先级丢弃门限，该网络设备收到3个组播节目(组播节目1、组播节目2和组播节目3)，可以对该组播节目1和组播节目2配置高丢弃优先级，对组播节目3配置低丢弃优先级。For another example, the priority queue 4 has three early discarding thresholds, and the three early discarding thresholds are a low priority discarding threshold, a medium priority discarding threshold, and a high priority discarding threshold, and the network device receives three multicast programs. (Multicast Program 1, Multicast Program 2, and Multicast Program 3), the multicast program 1 and the multicast program 2 can be configured with a high discarding priority, and the multicast program 3 with a low discarding priority.

应理解，该优先级队列的早丢弃门限的个数大于或者等于网络设备为组播节目配置的丢弃优先级的个数。It should be understood that the number of early discard thresholds of the priority queue is greater than or equal to the number of discarding priorities configured by the network device for the multicast program.

应理解，该预定义分类信息可以为预先规定好的组播节目分类信息，即网络设备接收到组播节目后，就可以确定对该组播节目配置哪一个丢弃优先级，换句话说，该网络设备为组播节目静态地配置丢弃优先级。It should be understood that the predefined classification information may be pre-defined multicast program classification information, that is, after the network device receives the multicast program, it may determine which discarding priority is configured for the multicast program, in other words, the The network device statically configures the drop precedence for the multicast program.

S122，根据该N个组播节目中每个组播节目的点播用户数，调整该N个组播节目中每个组播节目的丢弃优先级。S122. Adjust a discarding priority of each multicast program in the N multicast programs according to the number of on-demand users of each multicast program in the N multicast programs.

具体而言，网络设备接收到该N个组播节目后，可以根据组播节目的点播用户数，动态地对该N个组播节目中的每个组播节目配置丢弃优先级，当组播节目的点播用户数发生变化时，网络设备为该N个组播节目配置的丢弃优先级也相应发生变化。Specifically, after receiving the N multicast programs, the network device can dynamically set a discarding priority for each multicast program in the N multicast programs according to the number of on-demand users of the multicast program, when multicasting When the number of on-demand users of the program changes, the discarding priority configured by the network device for the N multicast programs also changes accordingly.

例如，网络设备根据组播节目的点播用户数，从高到低排序，动态地调整每个组播节目的丢弃优先级，点播用户数最多的节目，配置高丢弃优先级，点播用户数最少的节目，配置低丢弃优先级。每次用户加入或者离开组播节目时，根据点播用户数动态地调整丢弃优先级。在组播队列发生拥塞时，优先丢弃低丢弃优先级的组播节目，以保证高丢弃优先级的组播节目的质量。For example, the network device dynamically sorts the discarding priority of each multicast program according to the number of on-demand users of the multicast program, and dynamically adjusts the discarding priority of each multicast program, and the program with the highest number of on-demand users is configured with a high discarding priority and a minimum number of on-demand users. Program, configured with low drop priority. Each time a user joins or leaves a multicast program, the drop priority is dynamically adjusted according to the number of on-demand users. When the multicast queue is congested, the multicast program with the lower drop priority is preferentially discarded to ensure the quality of the multicast program with high discard priority.

又例如，网络设备接收到3个组播节目时，组播节目1的点播用户数最多，则为该组播节目1配置高丢弃优先级；组播节目3的点播用户数最少，则为组播节目3配置低丢弃优先级；为组播节目2配置中丢弃优先级。当组播队列发生拥塞时，优先丢弃配置了低丢弃优先级的组播节目3，以保证配置了中丢弃优先级的组播节目2和配置了高丢弃优先级的组播节目1的质量；或者，当组播节目发生拥塞时，优先丢弃配置了低丢弃优先级的组播节目3和配置了中丢弃优先级的组播节目2，以保证配置了高丢弃优先级的组播节目1的质量。For example, when the network device receives three multicast programs, the number of on-demand users of the multicast program 1 is the highest, and the multicast program 1 is configured with a high discarding priority; if the number of on-demand users of the multicast program 3 is the least, the group is the group. Broadcast program 3 configures a low drop priority; it discards the priority for multicast program 2 configuration. When the multicast queue is congested, the multicast program 3 with the low drop priority is preferentially discarded, so that the quality of the multicast program 2 with the drop priority and the multicast program 1 with the high drop priority are configured. Or, when the multicast program is congested, the multicast program 3 configured with the low drop priority and the multicast program 2 configured with the drop priority are preferentially discarded to ensure that the multicast program 1 with the high drop priority is configured. quality.

一段时间后，网络设备确定组播节目3的点播用户数最多，则将该组播节目3的丢弃优先级调整为高丢弃优先级；确定组播节目1的点播用户数最少，则将该组播节目1的丢弃优先级调整为低丢弃优先级。此时若组播队列发生拥塞，优先丢弃配置了低丢弃优先级的组播节目1，以保证配置了中丢弃优先级的组播节目2和配置了高丢弃优先级的组播节目3的质量；或者，优先丢弃配置了低丢弃优先级的组播节目1和配置了中丢弃优先级的组播节目2，以保证配置了高丢弃优先级的组播节目3的质量。After a period of time, the network device determines that the number of on-demand users of the multicast program 3 is the largest, and the discarding priority of the multicast program 3 is adjusted to a high discarding priority; and determining the number of on-demand users of the multicast program 1 is the least, the group is determined. The drop priority of the broadcast program 1 is adjusted to a low drop priority. At this time, if the multicast queue is congested, the multicast program 1 with the low drop priority is preferentially discarded to ensure the quality of the multicast program 2 with the drop priority and the multicast program 3 with the high drop priority. Or, the multicast program 1 configured with the low drop priority and the multicast program 2 configured with the drop priority are preferentially discarded to ensure the quality of the multicast program 3 with the high drop priority configured.

应理解，该网络设备在接收到该N个组播节目后，可以先静态的为该N个组播节目中的每个组播节目配置丢弃优先级，然后在根据组播节目的点播用户数，动态得调整该N个组播节目中每个组播节目的丢弃优先级。It should be understood that after receiving the N multicast programs, the network device may statically configure a discarding priority for each multicast program in the N multicast programs, and then count the number of users according to the multicast program.

When the multicast priority queue entered by multicast program 1, multicast program 2, and multicast program 3 is congested, if the depth of the priority queue exceeds the low early discard threshold, it is determined. The drop priority corresponding to the low drop threshold is the low drop priority. According to the low drop priority, it is determined that the multicast program corresponding to the low drop priority is the multicast program 3, and the packet of the multicast program 3 is not allowed to enter the multicast program. The priority queue is the same. If the depth of the priority queue exceeds the early-stage discard threshold, the packets of multicast program 2 and multicast program 3 are not allowed to enter the priority queue.
