Problems solved by technology

When the main ring links Device C--Device D and Device D--Device A are faulty, all devices are connected from the perspective of physical links, but due to the SRPT mechanism, PORT3 of Device C will be blocked, resulting in Device E and Device F can only be connected to Device D

Embodiment Construction

[0042] In the technical solution provided by the present invention, its core idea is to improve the original SRPT mechanism. In the case of RRPP main ring channel failure (that is, SRPT failure), the edge port is no longer simply blocked, but it is judged according to the actual situation whether BLOCK processing should be done.

[0043] Specifically, in a single-subring networking environment, when an SRPT failure causes the primary node of the subring to release the secondary port because it cannot receive its own hello message, since there is only one subring, a loop will definitely not occur , there is no need to block the edge ports at this time, and the sub-ring nodes can communicate with the main ring nodes normally.

[0044] In a multi-sub-ring networking environment, when an SRPT failure causes the master nodes of the two sub-rings to release their secondary ports, the two sub-rings will form a new ring with the help of edge nodes and auxiliary edge nodes, and the ori...

Abstract

The invention discloses a method for managing edge ports, which is applied to a rapid ring net protection protocol (RRPP) ring comprising a main ring, one or a plurality of subrings, edge nodes and auxiliary edge nodes. The method for managing an edge port comprises the following steps: when one or a plurality of subrings detects a RRPP main ring channel fault, opening self auxiliary ports by main nodes of the subrings, and blocking the self edge ports by the edge nodes of the subrings; maintaining the information of the main node auxiliary ports which are opened for the RRPP main ring channel fault and the subrings for blocking the edge ports of the edge nodes; selecting one subring from the subrings; and opening the edge port of the edge node of the selected subring. The invention can furthest ensure the maximum connectivity among devices on the RRPP rings.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for managing edge ports. Background technique [0002] With the development of network technology and the expansion of network influence, in network planning and actual networking applications, ring networks are mostly used to improve network reliability. Ring network technology is a technology that connects some network devices together through the shape of a ring to realize mutual communication. In order to avoid broadcast storms in the ring network, the STP (Spanning Tree Protocol, Spanning Tree Protocol) ring protection mechanism was initially adopted. However, in practical applications, the convergence time of the STP protocol is affected by the network topology, and it converges when the network diameter is large. It takes a long time and often cannot meet the requirements of transmitting high-quality data. [0003] In order to shorten the conve...
