Problems solved by technology

However, when the two clients are not in the same private network, the network cannot convert the address information of where the collected data is sent, resulting in devices in the private network being invisible to the external network, and thus unable to receive requests from the external network

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] The structure diagram of the present invention is as figure 1 As shown, the core of the present invention is based on the NAT penetration system and method of the data collection communication network in the power distribution room: at least one STUN (UDP simple NAT penetration) server is set in the communication network, and the user equipment is used as the STUN client 1. The user equipment obtains the external address information, port number information and address information of the accessed client corresponding to the NAT exit from the STUN server through the NAT device, and the user equipment carries the external address information and port number information of the NAT exit obtained by it In the load of the SIP control message, such as the SIP payload, and transmit the SIP control message to the accessed client through the NAT device.

Abstract

The invention provides NAT (Network Address Translation) penetration system and method based on power substation data acquisition. The system comprises a power substation user device (STUN (Simple Traversal of UDP (User Datagram Protocol) over NAT)) client 1) in a private network, a network address conversion device NAT and at least one STUN server (Simple Traversal of UDP over NAT) server. In the method, (a) the user device STUN client 1 acquires corresponding external address information of an NAT outlet, port number information and address information of an accessed client from the STUN server through the NAT device; and (b) the user device enables the acquired external address information of the NAT outlet and the acquired port number information to be loaded in a load of an SIP (Session Initiation Protocol) control message and transmits the SIP control message to the accessed client through the NAT device according to the client address information. The invention is easy to realize, strong in adaptability and good in expansion and effectively solves the NAT traversal problem in a power substation data acquisition communication network.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a NAT penetration system and method based on data collected by a power distribution room in the electric power industry. technical background [0002] With the continuous development and popularization of the Internet based on TCP / IP, its scale is getting bigger and bigger. The Internet mainly provides two services: TCP (Transmission Control Protocol, Transmission Control Protocol) and UDP (User Data Protocol, User Datagram Protocol). These two services are the basic technologies for private network devices in the Internet to access private network external resources. In order to allow the application equipment in the power distribution room in these private networks to access and communicate with each other, SIP and NAT technologies emerged as the times require. [0003] Usually, in the network communication, the sending end and the receiving end of t...
