Abstract

The present invention has a function which facilitates the user to surf the Internet, so as to facilitate the Internet user and to reduce the workload of the network managing personnel in particular in the place of high mobility of users.

Description

Network intelligent proxy technology

Technical field

Use on the gateway when network user surfs the Net a kind of agent skill group;

Background technology

At present, it generally is with static ip address (ip that webmaster distributes) that the network user surfs the Net and dynamically the ip address is by a gateway proxy online, and this all needs the manual intervention of carrying out more or less to safeguard; Especially true (because what section of user's ip address has in the mobile big network of some users, network access is also multifarious, when the user joins will surf the Net in the existing network time, webmaster must guides user correctly be provided with computer, thereby has increased the workload of webmaster); Intelligent agent technology can effectively reduce the workload of webmaster, to some users that are provided with different segment ip or different network access automatically identification handle respectively;

Summary of the invention

Intelligent agent technology mainly comprises following several aspect:

The ip address of 1 user's static state, gateway address, DNS and configuration are correct; Net on the gateway of use intelligent agent can be acted on behalf of;

2 users use static ip address, gateway address, DNS and dispose that at least one is incorrect; Use the gateway of intelligent agent can discern its ip address automatically and respond corresponding packet, enable correct communicating by letter with Internet;

3 users use the mode of dynamic address acquisition; Use the gateway of intelligent agent can discern and distribute correct ip address, gateway, DNS automatically;

When 4 users use the web proxy surfing, use the gateway of intelligent agent can discern its data flow automatically and can act on behalf of on net;

Description of drawings

Fig. 1 be intelligent agent module and each submodule at ip protocol stack position view, Fig. 2 is the location diagram of all submodules in the intelligent agent module.

Embodiment

1 Fig. 1 is the position of intelligent agent module at whole network protocol stack; Fig. 2 is all submodules of intelligent agent

2 from " mistake ip " the packet flow process sent of address;

From " mistake ip " the arp message that sends at first has " arp processing " module to receive and corresponding, the ip message of sending from " mistake ip " is received and handles (comprise check ip, revise ip, application ip) and delivers to upper strata ip layer afterwards and handle by " ip camouflage " module afterwards, and separating through " data-flow analysis " resume module before ip layer route needs to do the data flow acted on behalf of and this data flow is forwarded to corresponding program module again;

3 loopbacks are given " mistake ip " the packet flow process of address;

The message of coming from broker module or outer net is transmitted to " ip camouflage " module through the ip layer again and carries out the reduction of data necessary stream and send to " mistake ip " main frame via " data-flow analysis " module recovery agent packet.

Claims (2)

1 utilizes arp Cheating Technology agency " illegally " ip (not being this network segment) address to surf the Net.

When the 2 acting server ip that are provided with web agent functionality and setting as the user were not the address of this network segment, equipment can automatic transparent identification and agent client online.
