Embodiment Construction

[0022] In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] see figure 1 , is a flow chart of a frame relay compressed packet transmission method provided by an embodiment of the present invention, the method comprising:

[0024] 101: The first network device sequentially encapsulates M FR compressed packets with the same DLCI into a first data packet according to the packet encapsulation sequence number space N.

[0025] Wherein N is a positive integer greater than or equal to 1 and less than or equal to 255, M is a positive integer greater than or equal to 1 and less than or equal to N, that is, 1<=N<=255, 1<=M<=N.

[0026] Optionally, before the first network device sequentially encapsulates M FR compressed packets with the same D...

Abstract

An embodiment of the invention discloses a method and equipment for transmission of frame relay compressed messages. The method includes: using the first network equipment to package a serial number space N according to messages, to sequentially package M FR compressed messages with the same DLCI (data link connection identifier) into a first data package, and to transmit the first data package to the second network equipment, so that the second network equipment removes packaging of the first data packet and decompresses the M FR compressed messages, and the problems of low message decompressing success rate and more message synchronization times can be solved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a frame relay compressed message transmission method and equipment. Background technique [0002] Frame Relay (FR for short) is a statistical multiplexing protocol that can provide multiple virtual circuits on a single physical transmission line, and each virtual circuit is identified by a Data Link Connection Identifier (DLCI) To identify, the DLCI is only valid on the local interface and the peer interface directly connected to it. [0003] Frame Relay Forum 9 (FRF.9 for short) defines standards related to the Frame Relay Compression Protocol (Data Compression Protocol, DCP) for compressing FR messages to save network bandwidth , to reduce the network load and improve the efficiency of data transmission on the frame relay network. [0004] FRF.9 compression is based on streams. Different streams are distinguished by DLCI, and each FR compressed packet of the same stream i...
