Message forwarding method, system and provider edge equipment

Abstract

The invention provides message forwarding method and system and provider edge equipment. in the method, a U-PE (User Provider Edge) receives a service message transmitted by a virtual machine server and accesses a target medium carrying the service message in the service message into an MAC (Media Access Control) address; the U-PE (User Provider Edge) carries out addressing on the target MAC according to an MAC address table thereof; when the addressing of the target MAC address is not successful, the U-PE (User Provider Edge) packages the service message into a label message and forwards thelabel message to the N-PE (Network Provider Edge) through a PW (Pseudowire); and the U-PE (User Provider Edge) carries out addressing and forwarding on the label message according to the MAC address table thereof. The provider edge equipment comprises a first receiving module, an addressing module and a first forwarding module. The invention also provides a message forwarding system. The invention not only can support the virtual property of a data center realized by utilizing an H-VPLS (Hierarchy-Virtual Private LAN Service) technology, but also can reduce the networking cost of the data center to the maximum degree under the condition of high-capacity server deployment.

Description

technical field [0001] The present invention relates to communication technology, in particular to a message forwarding processing method, system and carrier edge equipment. Background technique [0002] With the continuous development of technology and the emergence of cloud computing / distributed computing, computing power has also become a commodity. For example, it can be sold externally based on virtual machines, and the data center can become the physical carrier of this commodity. Among them, Data Center (hereinafter referred to as: DC), as a data integration system, is usually composed of computing systems, storage systems, communication systems, network equipment, environmental control systems, and security systems. It is often used in corporate-level Computing and storage of core business, or computing and storage of company organization operating data. A virtual machine (Virtual Machine; hereinafter referred to as: VM) refers to a complete computer system with com...
