Device and method for telecommunicating between customer end application component and object server

Abstract

The invention is designed for use in a communication system having a relay device between the client side and destination server. The system thereof comprises a relay unit located at the client side and a relay server located at server side. A dedicated channel is set between the relay unit and relay server; the dedicated channel and the internal protocol traversing relay device are used to make communication; the relay unit and relay server are used to build the logical channel between the port of the main application component and the port of the destination server; the logical channel is build on said dedicated channel; the main application component and the destination server make normal communication that can traverse the relay device.

Description

technical field

[0001] The invention relates to network information interaction technology, in particular to a device and method for successfully realizing information interaction between a client and a server when forwarding equipment is introduced between a private network where a client is located and a public network where a server is located. Background technique

[0002] With the rapid development of the Internet (Internet), various emerging Internet applications emerge in endlessly, the Internet business volume is increasing rapidly, IP address resources are becoming more and more tense, and network security issues are becoming more and more prominent. In order to solve the increasingly scarce IP address resources and improve the security of enterprise networks, many enterprises and institutions or MANs indirectly access the Internet by using forwarding devices, such as network address translation (NAT) devices / proxy servers / firewalls.

[0003] However, currently some...

Examples

Embodiment Construction

[0046] The present invention will be further described in detail below through specific embodiments and accompanying drawings.

[0047] The core technical solution of the present invention is as follows: the client and the server are provided with transfer devices respectively, and the two transfer devices communicate through a dedicated channel, and all interactive information between the client and the server is forwarded to the server through the two transfer devices. other side.

[0048] An exemplary embodiment of the device according to the invention will first be described. figure 1 It is a structural schematic diagram of an embodiment of the device of the present invention. see figure 1 , the entire Internet application is divided into two physical parts: a large physical part is the local area network (LAN) part located in the forwarding device, that is, NAT / proxy / firewall, and this physical part is the client; the other physical part is located in the NAT / proxy / fire...
