摘要： Embodiments of the present invention provide a path checking method, a sink node device, and a communications system. The path checking method includes: a sink node determines whether a check packet sent by an ingress node by using a check multicast tree is received within a predetermined time, where the sink node is a node connected to a receiver, the ingress node is a node connected to a multicast source, and the check multicast tree and a first multicast tree have a same transmission path and different multicast addresses; and if the sink node determines that no check packet sent by the ingress node by using the check multicast tree is received within the predetermined time, the sink node determines a path fault exists in an upstream node of the sink node in the first multicast tree.

摘要： A Border Gateway Protocol Monitoring Protocol (BMP) module sends to a Border Gateway Protocol (BGP) module a request for acquiring a capability information set; the BGP module traverses BGP capability data stored in the BGP module to acquire all BGP capability data configured in the network device and sends all the BGP capability to the BMP module; and the BMP module sends to the monitoring server an initial capability information set message carrying all the BGP capability data and a device identifier of the network device. By means of capability extension of a network device, the network device can acquire, through interaction between a BGP module and a BMP module, all BGP capabilities configured in the network device and send all the BGP capabilities to a monitoring server, so that the monitoring server can fully understand actual capability supported by the entire network, further providing an effective basis for deployment of and decision on the entire network.

摘要： Embodiments of the present invention disclose a method, apparatus, and system for detecting performance of a layer 3 virtual private network. A first node creates an OAM instance according to OAM configuration information set by a user, and sends the OAM configuration information to a second nodet; the second node creates an OAM instance according to the OAM configuration information; and the first node performs OAM detection by sending an OAM packet to the second node and/or receiving an OAM packet from the second node, where the sending and/or receiving is implemented by using the OAM instance of the first node. According to the present invention, not only an OAM configuration procedure is simplified and manpower is saved, but also consistency of OAM configuration at two ends can be ensured. In addition, a configuration delay in this dynamic configuration manner may be ignored.
