Problems solved by technology

And it solves the shortcomings of the slow convergence speed of the STP protocol
However, the RSTP protocol cannot effectively solve the problem of network storms when the link is congested.
[0004]Because the spanning tree protocol itself is a slow protocol, it cannot meet the requirements of millisecond-level

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] In one embodiment, such as figure 1 As shown, a switch RSTP convergence enhancement method, the method includes the following steps:

[0032] Step S100: Configure local link fault detection configuration information for the link fault detection module of the switch, and perform linkage with the RSTP module of the switch. After the RSTP module recognizes the linkage identification of the link fault detection module, it detects The configuration information is negotiated with the peer switch for link fault detection parameters to obtain the negotiation result;

[0033] Step S200: When the negotiation result is that the negotiation is completed, periodically send the first fault detection protocol message, and if the second fault detection p...

Abstract

The invention discloses a switch RSTP convergence enhancement method, and the method comprises the steps that a link fault detection module of the switch configures local link fault detection configuration information, is linked with an RSTP module of the switch, and carries out link fault detection negotiation with an opposite-end switch according to the local link fault detection configuration information to detect communication link fault information; the communication link fault information is quickly notified to other switches in the network through a RUN message, the RUN message packaged with the communication link fault information and sent by other switches is received at the same time, and the RUN message is analyzed to quickly complete the corresponding processing of the RSTP protocol so as to achieve the purpose of quickly switching the link and further realize fault recovery. According to the method, the link state problem and the possible link single-pass problem can be sensed in time, the whole network and a processing mechanism are quickly notified through the RUN message, the convergence of the whole network and the link switching time are accelerated, and the RSTP protocol convergence time of the switch is improved from the second level to the millisecond level.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for strengthening RSTP convergence of a switch. Background technique [0002] In order to perform link backup and improve network reliability in an Ethernet switching network, redundant links are usually used. However, the use of redundant links will generate loops on the switching network, causing broadcast storms and unstable MAC address tables, resulting in poor user communication quality and even communication interruption. In order to solve the loop problem in the switching network, the Spanning Tree Protocol (STP) is proposed. [0003] STP is a protocol used to eliminate loops in LANs. Devices running this protocol discover loops in the network by exchanging information with each other, and block certain ports to eliminate loops. The rapid spanning tree protocol RSTP (Rapid Spanning Tree Protocol) is based on the STP protocol, and has made more...
