Abstract

The invention discloses network equipment and a method for adjusting link capacity by using the network equipment. The method comprises the following steps of: sending a loopback detection message through each port, wherein the loopback detection message carries a port number of the port which sends the loopback detection message and an attribute identifier M for uniquely identifying the network equipment; when the loopback detection message which carries the attribute identifier M is received, determining that the line state of a port N corresponding to the port number which is carried in the received loopback detection message in the network equipment is a loop; and when the negotiation of a link capacity adjustment scheme (LCAS) is required to be carried out, selecting the port of which the line state is not the loop to participate in the negotiation of the LCAS. By the invention, the influence of loopback on functions of the LCAS can be effectively avoided, so the whole transmission network is more stable.

Description

technical field

[0001] The invention relates to the technical field of network transmission, in particular to a network device and a method for adjusting link capacity thereof. Background technique

[0002] The concepts of concatenation and virtual concatenation are defined in the telecommunication standard ITU-T G.707 formulated by ITU-T, the Telecommunication Standardization Organization of the International Telecommunication Union. Multiple VCs (Virtual Containers, virtual containers) are combined and used as a single container with a complete bit sequence, and a single container containing multiple VCs is usually called a VCG (Virtual Concatenation Group, virtual concatenation group). Using concatenation and virtual concatenation technology can adapt the rate of Ethernet bandwidth and SDH (Synchronous Digital Hierarchy, synchronous digital series) virtual channel to realize flexible configuration of transmission bandwidth. Using virtual concatenation technology can espec...
