Embodiment Construction

[0019] The present invention aims to solve the problems of multifunctionality, high efficiency, high flexibility and high expansibility in link protocol processing, so that they can be realized conveniently by hardware. An identification field is set in the frame structure of the present invention, and through this field, the frame can conveniently realize unicast, multicast and broadcast functions on point-to-point lines in the IP telecommunication network. This function can avoid multiple repeated actions when processing point-to-multipoint services in unicast mode, and improve the processing efficiency of multicast and broadcast services.

[0020] A type field is set in the frame structure of the present invention, and the line test function, the link control function, and the identification function of various protocol packets are supported through this field. In terms of line test function, it supports both line state test and line quality test function. In terms of link...

Abstract

The present invention relates to a data exchange network, in particular to an encapsulation method of network link layer frames. Aimed at the defect of the inadaptation to the IP telecom network data encapsulation in the prior art, the present invention provides a new frame structure and utilizes the frame structure to realize the link layer function of an IP telecom network. The present invention applies an encapsulation method of IP telecom network data frames and is divided into three steps. Firstly, an identification field and a type field are set in the frame head field; secondly, the identification field defines the transmission pattern of the frame; and thirdly, the type field defines the information type of the frame. Adapting to different circuits, the present invention has the advantages of achievement of the purpose of reliability, high efficiency and convenient realization on the equipment, good expansibility, convenient realization of the bearing and processing of various data packages, realization of the transmission function of the link layer on various point-to-point physical channels and completion of the link control function and the transmission of various upper-layer package switching.

Description

technical field [0001] The invention relates to a data exchange network, in particular to a network link layer frame encapsulation method. Background technique [0002] At present, the telecommunication network technology is in a transition period of development. In order to truly adapt to the effective transmission of various services such as voice, data, and video, the telecommunication network technology has undergone technological explorations such as ISDN and ATM. With the rapid development of IP technology, people realize that the development direction of the next generation telecommunication network should fully learn from IP network technology, and should be an organic integration of IP technology and telecommunication network technology, so the concept of IP telecommunication network was proposed. IP telecommunication network is a new type of telecommunication network. Its main idea is to save complex dynamic routing protocols and simplify the complexity of core nod...
