Embodiment 1

[0033] see figure 1 , Embodiment 1 of the present invention, a method for fast link switching, comprising:

[0034] S1. Detect the link that needs to be switched;

[0035] The link fast switching method of the present invention is applied to the convergence of protocols such as RSTP, MSTP, STP, and ULPP. When a link switching occurs in the network, in the prior art, the unicast message address in the MAC table of the current node still points to the before switching Therefore, even after the link is switched over, the traffic is still wrongly forwarded to the port before the switch, resulting in packet loss. In order to avoid this situation, the present invention first switches the link when it detects that the link needs to be switched.

[0036] S2. Setting the first port where the switching is before is block;

[0037] The first port is block, that is: block, then link connection cannot be made through this port.

[0038] S3. Redirect the traffic sent to the first port du...

Abstract

The invention discloses a link fast switching method, comprising: S1. Detecting the link that needs to be switched; S2. Setting the first port where the switch is in the blocking state; S3. Using the chip fast processor / function processor function to The traffic sent to the first port due to unicast is redirected to the second port and the third port; S4. Set the second port to a blocking state, and set the third port to a sending state to perform link switching. The invention also discloses a link fast switching system. The link fast switching system and method of the present invention redirect the traffic directed to the port before switching to other ports, so that the time for deleting the port media access control address no longer affects the convergence time of the link, thereby realizing fast link switching. switch.

Description

technical field [0001] The invention relates to the field of routing and switching networks, and more specifically, relates to a method and system for fast link switching. Background technique [0002] In modern communication networks, a router is a device connected to various LANs and WANs in the Internet. It will automatically select and set routes according to the channel conditions, and send signals in the order of the best path. The English name of the router is Router. The hub of the network, the "traffic police". At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. [0003] Modern communication networks include several components that work together to allow mobile nodes to communicate with service providers. For...
