Communication method and equipment in multilink transparent internet

Abstract

The invention provides a communication method and equipment in a multilink transparent internet. The method comprises the following steps of: receiving a message sent to a second routing network bridge from other end systems or a first end system by a first routing network bridge in multiple routing network bridges connected with the first end system through an aggregation port, wherein the second routing network bridge is called as a virtual routing network bridge which is connected between the first end system and the multiple routing network bridges; performing routing operation on the message, wherein the routing operation comprises the routing operation of the first routing network bridge and the routing operation of the second routing network bridge; and continuously performing routing transmission on the operated message. The equipment comprises a receiving module, an operating module and a sending module. By utilizing the scheme provided by the invention, the problems of message out-of-sequence and the like caused by continuous vibration of network topologies stored in the routing network bridges are effectively solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a communication method and device in a Transparent Interconnection of Lots of Links (TRILL for short) network. Background technique [0002] TRILL is a connection layer (L2) network standard recommended by the Internet Engineering Task Force (IETF for short), which is used to solve the deficiency of the Spanning Tree Protocol (Spanning Tree Protocol, STP for short) in large data centers. In an L2 network, STP avoids loops by blocking redundant links, but at the same time it also wastes redundant link bandwidth. TRILL introduces the L2 network through the intermediate system to intermediate system routing protocol (Intermediate System to Intermediate System, referred to as: IS-IS) routing protocol, which solves the L2 loop problem while retaining the L2 multipath, or called equal cost Multipath (Equivalent Cost Multiple Path, referred to as: ECM...

AI Technical Summary

Problems solved by technology

[0005] When the first end system is connected to at least two RBs in the form of an aggregate port (Aggregate Port, referred to as: AP), the RB connected to the second end system in the TRILL network cannot determine which RB is connected to the first RB. On the end system, the RB connected to the second end system will send the message to one of the multiple RBs connected to the first end system for a while, and then send the message to multiple RBs connected to the first end system The other one causes the network topology saved in the RB connected to the second end system to continuously fluctuate, and the packets are out of order, which affects the application of the network.
