如图1所示，本发明实施例提供一种组播链路的检测方法，包括：
步骤1，第一网络设备根据服务器发送的控制命令，向和该第一网络设备互联的上游网络设备发送组播加入请求命令；
步骤2，所述第一网络设备接收所述上游网络设备基于所述组播加入请求命令发送的组播业务信息，并将所述组播业务信息发送至所述服务器。
本发明的上述实施例中，由于基于IGMP协议的系统中每个设备只能知道自己和下游方向的设备的组播协议和链路状态，为了让每个设备能够了解其上游网络设备的状态，需向所述上游网络设备发送组播加入请求(Report)命令，上游网络设备则根据所述Report命令，基于该IGMP协议向与该上游网络设备互联的网络设备发送组播业务信息，可选地，所述组播业务信息至少包括组播协议报文的类型、频率和接收间隔以及组播业务流的流量数据。

本发明的上述实施例中，所述第一网络设备接收的所述组播业务信息是所述上游网络设备通过Internet组管理协议发送的。
本发明具体实施例中，Internet组管理协议即IGMP协议，所述组播业务信息是所述上游网络设备根据Report命令请求，通过IGMP协议中的相关设定自动向所述第一网络设备下发的；其具体的下发过程在本发明实施例中不作具体描述。

可选的，还可以使用这个方法去检查整个网络对组播协议的支持情况，
如果某个节点测试成功或失败，那么就可以确定这个节点的上游链路支持或者不支持组播协议，其中，节点测试成功或失败的判断准则为该节点的组播业务流的流量数据是否大于0，若该流量数据大于0，则这个节点的上游链路支持组播协议；若该流量数据等于0，则这个节点的上游链路不支持组播协议。
可选地，承续上例，本发明实施例中，步骤5包括：
步骤51，预设一组播业务流的流量的门限值；
步骤52，若所述预设网络设备收到的所述组播业务信息中的组播业务的流量值大于零且小于所述门限值，确定该预设网络设备与其上游网络设备之间的链路出现故障；
步骤53，若所述预设网络设备收到的所述组播业务信息中的组播业务的流量值等于零，确定该预设网络设备出现的上游网络设备出现故障。
本发明的具体实施例中，如图3所示的应用场景下，假设对于图中的组播源的一次监测结果为：
网络设备1收到的组播流量为2MBPS；网络设备2收到的组播流量为1.5MBPS；网络设备3收到的组播流量为2MBPS；网络设备4收到的组播流量为1.5MBPS。
那么可以判断应该是设备1和设备2之间的链路出现了问题，导致组播丢包。
再假设某次的监测结果为：
网络设备1收到的组播流量为2MBPS；网络设备2收到的组播流量为0MBPS；网络设备3收到的组播流量为0MBPS；网络设备4收到的组播流量为0MBPS。
那么可以判断应该是设备1出现了问题，导致组播数据无法向下转发。
