Abstract

The invention discloses a flow distribution method and equipment in an SPBM network. The method and equipment is applied to the SPBM network provided with BEB equipment and/or BCB equipment. The method includes the steps of (1) synchronizing a link state database, and obtaining link bandwidth information and bandwidth information required by B-VLANs, (2) selecting a current B-VLAN to be processed according to the priority of the B-VLANs, screening a link meeting requirements of the current B-VLAN bandwidth according to the link bandwidth information and the bandwidth information required by the B-VLANs, calculating an SPT tree for the current B-VLAN to be processed, and accordingly obtaining an optical route, (3) determining the residual bandwidths not occupied by link interfaces currently according to the determined optimal route in topologies of a whole network, (4) when other B-VLANs need topology calculations, on the basis of the residual bandwidths of the link interfaces, repeating the steps of determining the optimal route and determining the residual bandwidths not occupied by the link interfaces currently, and accordingly finishing the topology calculations of all the B-VLANs. The situation that network resources are distributed according to flow bandwidths is achieved, and the network utilization rate is improved due to the fact that a suboptimal route transmits flow.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for traffic distribution in a shortest path bridge MAC-in-MAC mode (Shortest Path Bridging MAC mode, SPBM) network. Background technique [0002] Shortest Path Bridge (Shortest Path Bridge, SPB) is one of the Ethernet standards defined by IEEE802.1aq. It is a further extension of the Spanning Tree Protocol (STP, Spanning Tree Protocol). It aims to build a large flat non-blocking Layer 2 network. ISIS (Intermediate System-to-Intermediate System intra-domain routing information exchange protocol, intermediate system to intermediate system intra-domain routing information exchange protocol)-SPB to share the link status in the network, and each node in the network calculates the link status between each node in parallel The shortest path avoids the instability caused by the use of the STP protocol and the inefficiency of some links. At the same tim...
