Problems solved by technology

If Chip 2's P 2 Also to Chip 1's P 3 The port sends packets, which will cause unnecessary congestion at this time, resulting in reduced system performance
It can be seen from this that in the network equipment of the distributed system and the super network equipment formed by stacking multiple equipment, the link failure port still consumes the resources and bandwidth of the system

Abstract

This invention discloses a system and a method for avoiding congestion of network devices, in which, a master control board and line cards transmit information via inter-plate communication channels, a link state inform module obtains the state change information of its line card port and synchronizes it to the master control board, a link state alter process module stationed in the master control plate gets the information then sends the VLAN information and port state information to related line cards to delete ports with disabled links from the VLAN and only writes the ports with valid links when writing in the chips.

Description

technical field [0001] The present invention relates to a kind of system that avoids the congestion of network equipment, especially relate to various network equipments such as switchboard and router, this system fundamentally eliminates the consumption of the buffer zone when cross-chip forwarding by changing the VLAN (virtual local area network) configuration of network equipment dynamically, Reduce congestion. The invention also relates to a method for avoiding network equipment congestion by timely deleting the failed port from the corresponding VLAN so as to improve the data packet processing capability of the system. Background technique [0002] Such as figure 1 As shown, in the network equipment of the distributed system and the super network equipment formed by stacking multiple equipment, the system is composed of multiple data processing chips (network processors or ASIC chips) connected to each other, that is, directly connected back to back or through Crossbar...
