[0026] Fig. 1 shows the typical networking structure of the same DLCI solution for multi-service multiplexing adopted in this embodiment. The middle part of the figure represents the frame relay switching network, which connects multiple switches, and the frame relay link between every two switches Only one DLCI resource can be used for interaction between routes, and multiple services need to be exchanged between switches through the frame relay network.

[0027] FIG. 2 shows the composition of an apparatus 200 for multiplexing the same data link connection identifier for multiple services according to the first embodiment of the present invention.

[0028] As shown in Figure 2, the device includes: a configuration module 202, configured to configure the frame relay port operating parameters and data link connection identifier resources of the frame relay port; Multiple services for transmission through the channel connection identifier are registered; the frame relay protoco...

Abstract

The device includes following modules: configuration module in use for configuring working parameters of frame relay port and resources of data link connection ID of frame relay port; registration module in use for registering multiple services of using same data link connection ID to carry out transmission; frame relay protocol process module in use for accomplishing interaction in frame relay protocol to frame relay protocol port at opposite terminal; sending module for frame relay carried service message in use for sending service message; receiving module for frame relay carried service message in use for receiving service message, and handing in the receiving service message to corresponding service module to process. In addition, the invention also discloses the method for multiplexing same data link connection ID for multiple services. The invention solves issues for carrying and transmitting multiple services under network condition of lack of frame relay DLCI resources.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a device and method for multiplexing the same data link connection identifier for multiple services. Background technique [0002] With the rapid development of modern information technology, the network is undergoing a broadband revolution to meet the increasingly higher requirements of services on transmission bandwidth. But the traditional frame relay technology did not disappear immediately with the advent of the broadband technology revolution, but still played a very important role in some traditional communication fields. [0003] In some application scenarios, the data link connection identifier (DLCI) value of frame relay is very tight as a resource, but with the continuous development of the network, more and more business requirements are put forward. In this case , how to use limited frame relay resources to carry and transmit more services is a problem...
