Abstract: The present disclosure discloses example communication method and apparatus. One example method includes a first network device receiving first state information from at least one second network device, where the first state information indicates whether the at least one second network device is capable of providing a service in a next state. Third state information of the at least one second network device is received, where the third state information indicates a current state of the at least one second network device and includes user state information corresponding to at least a portion of a plurality of beamforming weight directions of the at least one second network device. A network topology is determined based on at least the first state information and the third state information, and after the first network device and the at least one second network device in a next state are networked.

Abstract: Embodiments of the present invention disclose a method, an apparatus, and a system for detecting a multi-protocol label switching ring network. The method includes: initiating, by a ring ingress node, a detection request packet; determining a ring label switched path LSP forwarding equivalence class FEC corresponding to the detection request packet, and encapsulating the ring LSP FEC into the detection request packet; sending the detection request packet after encapsulation to a ring egress node; and determining whether a detection reply packet sent by the ring egress node is received; if yes, determining that the ring LSP is connected; otherwise, determining that the ring LSP is not connected. Therefore, the embodiments of the present invention are able to directly detect connectivity of a ring LSP, solving the problem in the prior art where an interference exists during detection of the ring LSP connectivity.

Abstract translation: 本发明的实施例公开了一种用于检测多协议标签交换环网的方法，装置和系统。 该方法包括：由环入节点发起检测请求报文; 确定与所述检测请求分组相对应的环标签交换路径LSP转发等价类FEC，并将所述环LSP FEC封装在所述检测请求分组中; 将封装后的检测请求报文发送到环出口节点; 以及确定是否接收到所述环出口节点发送的检测应答分组; 如果是，则确定环路LSP已连接; 否则，确定环路LSP未连接。 因此，本发明的实施例能够直接检测环形LSP的连通性，解决了在检测环路LSP连通性期间存在干扰的现有技术中的问题。
