Problems solved by technology

If the encapsulation information configured on the sending end and the receiving end of the service is inconsistent, for example, if the sending end configures the standard FR encapsulation format and the receiving end configures the Cisco encapsulation format, the receiving end may not be able to parse the packet, causing the sending end to Waste of resources (for example, the sender may send the same message repeatedly)
Currently, the link layer maintenance protocols of FR, HDLC, and ATM do not deal with this situation.

Embodiment Construction

[0032] In the embodiment of the present invention, the sending end first performs link layer negotiation with the receiving end, and the link layer negotiation is successful, and then performs network layer service configuration check and network layer negotiation, if the negotiation fails, the sending end will not send the network layer bearer message , in order to achieve the purpose of saving resources.

[0033] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] In the embodiment of the present invention, the protocol management of HDLC, FR and ATM between the sending end and the receiving end is divided into two levels, link layer management and network layer management. The link layer management is responsible for the reachability management of the link, and the network layer management is responsible for the management related to the network layer business. Correspondingly, two new in...

Abstract

The invention relates to the field of digital communication, in particular to a method and device for transmitting messages in a wide area network. The method is as follows: the protocol management of the wide area network is divided into two layers, and the link layer negotiation is performed first, and then the network layer negotiation is performed after success, and if the negotiation fails, the sending end does not send the bearer message of the network layer. In this way, the embodiments of the present invention can avoid the defects in the prior art, that is, the receiving end cannot parse the message due to the different message encapsulation formats of the sending end and the receiving end, resulting in a waste of resources at the sending end, so that the sending end and the receiving end message exchange between them.

Description

technical field [0001] The invention relates to the field of data communication, in particular to the related technology of wide area network link message bearing. Background technique [0002] With the development of Internet technology, the network structure is becoming more and more complex. According to different communication protocols, the connection of computer wide area network is divided into frame relay network, ATM (Asynchronous Transfer Mode, asynchronous transfer mode) network, ISDN (Integrated Services Digital Network, Integrated Services Digital Network) network and PPP (Point-to-Point Protocol, point-to-point link layer protocol) network and so on. [0003] Due to different networks, common Layer 2 encapsulations for WAN include FR (Frame, Frame Relay), HDLC (High-Level Data Link Control, Advanced Data Link Control), PPP, and ATM. Among them, HDLC and PPP belong to point-to-point transmission and do not need information such as link layer addresses; FR and A...
