Embodiment Construction

[0019] As we all know, in an IP-based network, the link layer provides data transmission services for the network layer. Link maintenance (that is, establishment, maintenance, and teardown) of the link layer is the basis for the work of the network layer, and the establishment process of the link layer is before the actual data forwarding. In view of the above-mentioned characteristics of the link layer, the basic ideas of the present invention are as follows: figure 2 shown, including the following:

[0020] Make the link layer carry relevant node information in the process of establishing a link, that is, the frame with the function of establishing a link or starting a link in the link control frame (referred to as a link establishing frame in this patent) and related The acknowledgment frame adds a field describing node information. The link establishment frame here may also be a message sent by nodes at both ends of the link when the state of the link layer changes from...

Abstract

The invention discloses a method for acquiring information of neighbor nodes in an IP telecommunication network system, which comprises the following steps: (1) setting fields describing node information in an establishment link frame and a response frame thereof of a link layer; (2) leading the establishment link frame to carry the node information when a link between nodes in the IP telecommunication network system and the neighbor nodes is established; (3) judging whether the link is allowed to be established when the neighbor nodes receive the establishment link frame; sending the response frame to the nodes and carrying the information of the neighbor nodes in the response frame on one hand, and recording the node information carried in the establishment link frame on the other hand when the establishment is allowed to carry out; and not responding when the establishment is not allowed to carry out; and (4) recording the information of the neighbor nodes carried in the response frame when the nodes receive the response frame. The utilization of the method can automatically and high-efficiently find the neighbor relationship of the nodes, thereby automatically providing a technical basis for automatically acquiring a network topology for the network system.

Description

technical field [0001] The invention relates to a method for obtaining neighbor node information through the process of establishing a link in an IP telecommunication network system, and belongs to the technical field of communication. Background technique [0002] The IP telecommunication network system is a new concept proposed by the inventor in the invention patent with the patent number ZL200410037641.0. It adopts a unique internal and external double-layer structure and dual-address addressing mode. It is composed of at least one re-addressed connectionless data network (referred to as PTDN network) in the inner layer and multiple IP networks in the outer layer, as well as multiple edge Gateway Device (ED). There is also a network management device (referred to as network management) inside the relocation connectionless data network, which manages the access device (AR), aggregation device (MR) and core device (CR) in the relocation connectionless data network at the ...
