Embodiment Construction

[0049] Aiming at the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a technical solution for data transmission. In this technical solution, by introducing the Hub-Spoke architecture into the SPB network, the Hub-Spoke architecture is a networking mode in which there is a central node (ie, Hub node) and multiple branch nodes (ie, Spoke nodes) in the network. In the Hub-Spoke networking mode, branch sites cannot communicate directly with each other, but must communicate through the central site, so that the central site can manage data traffic in a unified manner. In the embodiment of the present invention, a BEB device in the SPB network is selected to be configured as a Hub node in the Hub-Spoke architecture, and other BEB devices are configured as Spoke nodes in the Hub-Spoke architecture, wherein the BEB device as a Hub node is called It is a HubBEB device, and a BEB device as a Spoke node is called a SpokeBEB device, and...

Abstract

The invention discloses a data transmission method and equipment, the method includes: when the Spoke? When the BEB device receives the packet sent by the user side, the Spoke? The BEB device encapsulates the message into a MAC-IN-MAC message, and forwards the message to the HubBEB device through the backbone network core bridge BCB device; the Hub? The BEB device receives the MAC-IN-MAC message forwarded by the BCB device, strips off the MAC-IN-MAC tunnel header of the MAC-IN-MAC message, and forwards it to the server; the Hub? The BEB device receives the processed message returned by the server, queries the MAC table according to the destination MAC address of the processed message, and forwards the processed message according to the query result. In the present invention, support is provided for the realization of flow statistics and monitoring in the SPB network, and network security can be enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and equipment. Background technique [0002] The SPB (ShortestPathBridge, shortest path bridge) protocol is one of the Ethernet standards defined by IEEE (InstituteOfElectricalAndElectronicsEngineers, Institute of Electronics and Electrical Engineers) 802.1aq. The non-blocking two-layer network uses SPB-ISIS (Intermediatesystemtointermediatesystem, intermediate system to intermediate system) to share the link status in the network, and each node in the network calculates the shortest path between each node in parallel, avoiding the use of STP (SpanningTreeProtocol, The instability caused by Spanning Tree Protocol) and the low utilization of some links. At the same time, the SPB configuration management is simple and the cost is low, which can be aimed at the application of the Ethernet in the data center. SPB integrates the advantages of 802.1ah and ...
