Private network through network education training underlayer soft switching platform system and soft switching method

Abstract

The disclosed bottom soft-exchange platform for private network crossing network education training system comprises: a common network education and training soft-exchange platform device, some crossing severs in different service areas, and a swarm decision server set on the soft-exchange platform. Wherein, the crossing server communicates with user by TCP / IP protocol, and uses TRANS protocol for communication with the swarm decision server. The user needs no special protocol, nor modifies NAT, agent server or firewall. Thereby, this invention saves much capital and equipment modification, and improves the parallel processing capacity of bottom soft-exchange platform greatly.

Description

1. Technical field [0001] The invention relates to a computer network system, in particular to a bottom layer soft switch platform system for private network traversal network education and training and a soft switch method realized by the system. 2. Background technology [0002] At present, VOIP and two-way video communication based on IP technology in the world have begun to be popularized and applied among the public, and a large number of soft exchange platforms based on NGN international standard SIP protocol, various computer soft terminals and hard terminals are used. In the network education training system, to solve the two-way video communication using the general visual hardware terminal, the soft exchange platform system based on the SIP protocol is basically used as the underlying communication platform system. However, because the current Internet network still uses the IPv4 standard, there is a shortage of public network IP addresses, forcing many enterprises...

Problems solved by technology

[0006] 3. Add a TURN server on the softswitch platform, and use the TURN protocol support in the communication terminal to solve almost all NAT devices and some firewall problems. The disadvantage is that the TURN server must be added and the client needs to support the TURN protocol, and each NAT There can only be one communication terminal

[0007] 4. The softswitch platform transforms the existing firewall or NAT by using the MidCom method to make it support the MiddleBox protocol and communicate with the remote MidCom Agent to solve the problem that the user terminal uses a private network address. The disadvantage is that the amount of equipment transformation is large and the investment huge

[0008] Although the above-mentioned similar products provide some solutions to private network penetration, they all need to greatly modify the underlying softswitch platform of the existing network education and training system, and upgrade the user terminal or the intermediate NAT device. is difficult to achieve
