Message forwarding method and device

Abstract

The invention discloses a message forwarding method and device. The method includes the steps that all node devices annunciate newly-learnt local MAC addresses and a WLAN which the MAC addresses belong to towards other node devices on the control surface of a large layer-2 network through a broadcast tree which can reach all the node devices in the large layer-2 network; the node devices receive the local MAC addresses, annunciated by other node devices, of other node devices from the broadcast tree, and original MAC address forwarding table items are generated according to large layer-2 network forwarding table items generated based on a large layer-2 network protocol in advance; after the node devices receive unicast data messages on the data plane of the large layer-2 network, matching is carried out in the original MAC address forwarding table items according to the destination MAC addresses of the unicast data messages and the WLAN which the MAC addresses belong to, outcoming interfaces of the matched table items are used for forwarding the unicast data messages directly instead of conducting large layer-2 network protocol packaging. According to the message forwarding method and device, L2 unicast traffic forwarding based on the large layer-2 network is achieved.

Description

technical field [0001] The invention relates to multicast technology in the field of communication, in particular to a message forwarding method and equipment. Background technique [0002] STP (Spanning Tree Protocol, Spanning Tree Protocol) is used in the traditional three-tier data center architecture to optimize the path from the client to the server and support connection redundancy. Due to the convergence performance of STP, etc., the network size of STP generally does not exceed 100 switches. At the same time, because STP needs to block redundant devices and links, it also reduces the bandwidth utilization of network resources. Traditional STP-based backup equipment and link solutions can no longer meet the scale and bandwidth requirements of the data center, and the STP protocol's fault convergence time of several seconds to minutes cannot meet the reliability requirements of the data center. Therefore, it is necessary to have new technologies that can make full us...

Problems solved by technology

[0007] In the existing technology, the processing method when the large-scale layer 2 networking technology and other technologies coexist in the network requires additional configuration of the loopback port, which wastes the device port. At the same time, the loopback port becomes the forwarding bottleneck of the system, with low performance and large delay.
