Data communication network configuration method, gateway network element and data communication system

Abstract

The invention discloses a DCN configuration method, a gateway network element and a data communication system. The gateway network element transmits a broadcast message having the IP address of a network management server to a non-gateway network element in a management area. The network element mark registration information transmitted by the non-gateway network element after the broadcast message is sent is acquired. A public network IP address and a private network IP address for device management are distributed by the non-gateway network element, and a NAT mapping table is formed and stored. The NAT mapping table is registered in the network management server. The message exchange between the non-gateway network element and the network management server can be achieved based on the NAT mapping table. When the message exchange is conducted between the network management server and the non-gateway network element, the gateway network element only needs to conduct a NAT conversion on the message. Accordingly, the CPU load of the gateway network element is reduced, the network element number in the management area is effectively increased and the forwarding efficiency of the message in the management area is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a data communication network configuration method, a gateway network element and a data communication system. Background technique [0002] The backhaul bearer between the mobile base station and the wireless core equipment is carried by the fixed network equipment. In order to realize the remote deployment of the wireless backhaul, the existing technology adopts the data communication network (Data Communication Network, DCN) system to provide the network equipment with the communication function of management access and management control information, so that the network management server center can complete the communication of each Remote deployment and management of devices. [0003] A DCN system network is composed of a network management server, gateway network elements, non-gateway network elements and the connecting lines or networks betwe...

AI Technical Summary

Problems solved by technology

[0008] The inventor has found through research that at least the following defects exist in the prior art: since all management messages must be analyzed at the application layer by the gateway network element, the CPU load of the gateway network element is too large, so the network elements in the management domain The number is limited, and the forwarding efficiency of IP packets in the management domain is not high
