Embodiment Construction

[0094] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0095] In the present invention, the IWF plays an extremely important role in the process of network interworking, connecting two different types of networks, such as ATM network and Ethernet network. The schematic diagram of the basic network simulation model of the present invention is shown in FIG. 2 .

[0096] As shown in Figure 2, at the edge of the metro Ethernet, a tunnel is formed between two media access control service access points (MACSAP) MAC SAP1 and MAC SAP2. A pseudowire (PW), that is, a virtual connection emulation of the Ethernet, can be configured on this tunnel to establish a mapping relationship between the ATM VPC / VCC and the PW. Map the ATM VPC / VCC to the PW on the IWF at one end, and perform reverse mapping on the IWF at the other end to o...

Abstract

The invention used for realizing the ATM simulation of ATM network in Metro Network. Based on PW mapping technology, the invention provides a switching method between ATM cell and Ethernet frame and its relevant format; To-MAN IWF (InterWorking function) completes the works of packaging ATM cell into the Ethernet frame; To-ATM IWF completes the work of the recombining the ATM cell in the Ethernet frame information.

Description

technical field [0001] The present invention relates to Ethernet (Ethernet Network) technology, in particular to a method and device for carrying Asynchronous Transfer Mode (Asynchronous Transfer Mode, ATM) cells by Ethernet. Background technique [0002] With the continuous development of Ethernet technology, operators can directly use Ethernet technology to provide various services in the metropolitan area network. At the same time, the development of multi-type services also promotes the transition from Ethernet to carrier-class Ethernet with higher reliability. In this process, Ethernet faces the problem of realizing intercommunication with other networks. Among them, in the traditional technology, the interconnection networking mode of the ATM network and the Ethernet is to carry the Ethernet service on the ATM network, and realize Ethernet local area network emulation (LAN Emulation Over ATM, LANE). With the gradual development of Ethernet as the core of the MAN, it i...
