Message forwarding method and device in data center network

Abstract

The invention provides a message forwarding method and device in a data center network. According to the message forwarding method and device provided by the invention, when detecting that a link for transmitting a message has a fault, CORE equipment sends a target MAC (Media Access Control) address of the message, and when ACCESS equipment receives the MAC address sent by the CORE equipment, a link corresponding to a port which receives the MAC address is used as a limited link of the MAC address, so that when the message is sent to the MAC address again, the limited link corresponding to the MAC address is not used. Therefore, the CORE equipment which sends the MAC address does not receive the message with the target MAC address of the sent MAC address. Furthermore, the problem, such as a load of the links among the machine frames is increased, caused by the condition that the links among machine frames of the CORE equipment are used for carrying out flow transmission can be avoided, so that the flow transmission property is improved.

Description

technical field [0001] The present application relates to network communication technology, in particular to a message forwarding method and device in a data center network. Background technique [0002] At present, the data center network pursues 10 Gigabit non-blocking, loop-free, single-layer high-performance switching, and its typical networking is as follows: figure 1 As shown, it mainly includes: core (CORE) equipment and access (ACCESS) equipment. Among them, CORE equipment adopts high-performance switching structure to realize non-blocking switching, and ACCESS equipment adopts 10 Gigabit access to realize non-blocking uplink. [0003] In the data center network, in order to make full use of the forwarding capabilities of CORE devices, and realize load sharing and disaster backup between CORE devices, ACCESS devices and CORE devices are fully connected. However, this full connection method will generate loops, for example, the link connecting the same ACCESS device...

AI Technical Summary

Problems solved by technology

It can be seen that when the local link between a Chassis and ToR in the IRF system fails, the traffic originally forwarded by the faulty link is transferred to the inter-chassis link between the Chassis. Although this can realize traffic forwarding, However, it will increase the load of the links between chassis, and, because the link bandwidth between chassis is relatively low, it will also affect the traffic forwarding performance
