Control system and data message transmission method in Ethernet

Abstract

The invention relates to a control system of Ethernet and data report transmission method. Wherein, it is characterized in that: the control system according to the control protocol of two layers of Ethernet obtains the chain information of Ethernet; according to the chain information, building and maintain the network topology of Ethernet, the control system according to the connection built by said network topology requests to calculate the route between the terminal bridges, and transfer the path information according to the route setting; each network bridge data system according to the transfer path information to transfer the data report. The invention can realize the management of transmitted data in the Ethernet, to control the data flux, without changing the packing structure of Ethernet data plane, and without lower cost.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a control system and a data message transmission method in the Ethernet. Background technique [0002] The Ethernet system consists of three subsystems, that is, the data forwarding system, the control system, and the management system. The data forwarding system is referred to as the data system. These three subsystems may also be called: data plane, control plane, and management plane. [0003] The data plane directly forwards and processes user data packets; the control plane does not directly process user data packets, but through control protocols such as STP / MRP / LLDP (Spanning Tree Protocol / Multiple Registration Protocol / Link Layer Discovery Protocol), etc. Obtain the network topology, provide configuration of relevant parameters and status for user data flow connection establishment, and provide reliability guarantee for it; the management plane is responsib...

Problems solved by technology

[0010] 1. Since the traditional Ethernet system adopts connectionless technology, it cannot provide process engineering services, that is, it cannot provide reliable services that meet user requirements through optimized use of network resources according to user business needs and network resource conditions

[0011] 2. In order to prevent loopback, traditional Ethernet uses spanning tree to forward user data packets, and spanning tree is a pruned topology of a bridged network topology, so that some links in the bridged network are blocked, and network topology resources cannot be effectively used

[0012] 3. Since the existing Ethernet adopts the spanning tree protocol and generates the shared topology of the bridge network through distributed operations, there is still an election process for the determination of the root of the tree, so that the convergence time of the spanning tree is long. In this way, when the network Low business recovery efficiency in the event of a failure

This technology does not consider the bandwidth resource requirements of the end-to-end service data flow, but only considers the establishment of data forwarding tables based on the destination address. It cannot realize Ethernet traffic engineering based on network resource usage and service requirements.
