Embodiment Construction

[0017] As shown in Figure 1 and Figure 3, the present invention distributes MAC address to the remote network equipment connected with Ethernet through frame relay, uses this MAC address as the identity mark of remote network equipment, and establishes this MAC address and frame relay interface ID and DLCI mapping table.

[0018] In this paper, Ethernet is regarded as a local network. Relatively speaking, the remote network device is a network device connected to Ethernet by frame relay. The protocol conversion described in this article refers to the conversion of data packets conforming to one protocol into data packets conforming to another protocol, including data unpacking and encapsulation, for example, converting data packets conforming to the Ethernet protocol into those conforming to the frame relay protocol. packet, or the reverse transformation.

[0019] The processing of the data packet sent by the remote network device to the device in the Ethernet includes the fo...

Abstract

The method relates to communication technique, especially related to frame relay in WAN protocol and Ethernet in LAN protocol. The invention allocates MAC address for remote network device connected by passing through frame relay and Ethernet. The MAC address is as id of remote network device, and map table between MAC address and network identity of frame relay. Based on the map table, conversion and forwarding data between frame relay and Ethernet protocol are carried out. In the invention, transmission channel is transparent for IP layer and upper application layer by using technique of frame relay and Ethernet interconnection to complete conversion between practical protocols. Features are: supporting relevant route protocol, flexible network planning. Assigning MAC address for remote network site by central server self. The invention can be realized in access devices in transmission network so as to provide richer interface than router to remote network site.

Description

technical field [0001] The invention relates to communication technology, in particular to wide area network protocol frame relay (FrameRelay) and local area network protocol Ethernet (Ethernet). Background technique [0002] Frame relay is the mainstream wide area network protocol today, which can support data, fax and voice applications. It is developing very rapidly, and the coverage of frame relay network is quite wide. The Frame Relay protocol is applied. [0003] In today's LAN field, Ethernet occupies a dominant position, because network construction and planning are very simple, and various data communication equipment and telecommunication equipment have Ethernet interfaces, the bandwidth is very high and very flexible, and can provide 10M / 100M / 1000M, and the 10G Ethernet standard was approved by IEEE in 2002, and the price is very low. [0004] At present, it is a typical networking mode for multiple remote sites to access a central server. For example, a compan...
