Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] In a method for realizing data intercommunication between sites in a communication network provided by the present invention, when configuring a DCN network segment IP for a gateway site of a certain network under a DCN network or a similar topology, the access to the DCN is recorded in the configuration information. IP information of the gateway site of the DCN network or other networks with similar topologies (only need to record the IP information of the gateway sites of other networks that need to communicate between sites through the DCN network or similar topology). During the data exchange process between each station in the communication network and the network management system, the non-gateway station records the IP information of the gateway station (hereinafter referred to as the direct gateway) used when it communicates with the network management ...

Abstract

The invention discloses a method for realizing data interchange among stations in a communication network, which comprises the following steps: initiating a path inquiry request on a destination station to an attributive gateway station by using a source station; transmitting an assistant inquiry request to other network gateways by using the gateway station; inquiring the destination station for respective networks by using the other gateways and transmitting an answer to the source station through the gateway station attributive to the source station if the answer is received; establishing an indirect communication link table of the source station, the gateway station attributive to the source station, the gateway station attributive to the destination station and the destination station by using the source station and transmitting an indirect massage along an indirect communication chain; and recording and communicating with the source station by using the indirect communication chain and after the destination station receives the indirect message. Only a very short packet header is added for the data massage on an application layer and required to be resolved by the gateway station for transmission without adding network redundant traffic or adding the additional burden of the communication station.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to a method for realizing data intercommunication between stations in the communication network. Background technique [0002] In the optical communication network, the optical transmission equipment is often accessed through the Ethernet access site of the DCN network provided by the operator, and communicates with the network management through the DCN network. Since the IP addresses provided to access the DCN network are generally relatively small, the IP addresses obtained by the optical transmission equipment to enter the DCN network are also relatively small. access site, which cannot meet the practical application. In order to solve this problem, the current common practice is to design the access site connected to the DCN network as a gateway site, and connect multiple downlink member sites through the downlink port of the gateway site (downlink member site Using a pri...
