Abstract

The invention discloses a traffic distribution method and equipment in an SPBM network, which is applied to an SPBM network including BEB equipment and / or BCB equipment, including: synchronizing a link state database, obtaining link bandwidth information and B-VLAN required Bandwidth information; select the currently processed B-VLAN according to the priority of the B-VLAN, and filter out the link that meets the bandwidth requirements of the B-VLAN for the currently processed B-VLAN according to the link bandwidth information and the bandwidth information required by the B-VLAN Calculate the SPT tree for the currently processed B-VLAN to obtain the optimal path; in the whole network topology, according to the determined optimal path, determine the current unoccupied remaining bandwidth of each link interface; when there is When other B-VLANs need to perform topology calculation, based on the remaining bandwidth of each link interface, repeat the above steps of determining the optimal path and determining the current unoccupied remaining bandwidth of each link interface to complete all B-VLAN The topological calculation realizes the allocation of network resources according to the traffic bandwidth, and forwards traffic through the suboptimal path, which improves the network utilization rate.

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, each node in the network calculates the shortest path between each node in parallel , avoiding the instability caused by the use of the STP protocol and the inefficiency of some links. At the same time, SPB is easy t...
