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 th

Embodiment Construction

[0021] As shown in Figure 1, the topological diagram of the underlying softswitch platform for private network traversal network education and training, which includes multiple traversal servers in different service areas, and the high-speed broadband Internet management system located on the softswitch core platform for network education and training A cluster decision server for traversing servers in each area.

[0022] The hardware of the cluster judgment server can use Intel P4 CPU as the main CPU, use 256Mbyte memory, use SCSI hard disk as storage medium, and use 100Mbps network card as network interface. It is divided into two main and standby devices, and a serial cable is used to connect the two devices to detect heartbeat. Once the main device has a problem, the backup device will automatically switch to the main device immediately, and once it detects that the main device is good, it will switch back.

[0023] The traversal server can use two Intel XEON CPUs as the ...

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...
