A Method of Network Transparent Proxy

Abstract

The invention discloses a network transparent agent method, which comprises the following steps: in the data packet input module, modify the destination IP address of the data packet sent to other than the local machine to the IP address of the corresponding local network bridge, and change the IP address of the local network bridge The data packet is uploaded to the upper-layer application layer protocol stack, and the upper-layer user software can act as a proxy for the data flow. After the data packet is processed by the upper-layer user business software, the data packet will pass through the data packet output module. The information specified in the file modifies the destination IP address of the data packet to the most original IP address, and sends the data packet to the original destination device. The present invention combines the existing network bridge technology with the traditional network application layer proxy technology, and combines the advantages of the transparency of the network bridge, the convenience of implementation and the flexibility of the application layer proxy, and is fully compatible with the existing network applications of users, fully Use the services provided by the operating system and application layer to achieve rapid network application development.

Description

technical field [0001] The invention relates to a network transparent agent method. Background technique [0002] At present, the network structure of each company or unit is huge and complex. To connect new network devices to the user's existing network structure requires the user's network administrator to configure the existing network, which will inevitably increase the workload of the network administrator. , and the reliability and stability of the network cannot be guaranteed. [0003] However, for the traditional gateway-based or agent-based network service processing system, it is also necessary to modify the configuration of the user's network environment when accessing the user's network environment, which is extremely inconvenient to install and implement.

[0002] At present, the network structure of each company or unit is huge and complex. To connect new network devices to the user's existing network structure requires the user's network administrator to configure the existing network, which will inevitably increase the workload of the network administrator. , and the reliability and stability of the network cannot be guaranteed

[0003] For the traditional network business processing system based on gateway or proxy, it is necessary to modify the user's network environment configuration when accessing the user's network environment, which is extremely inconvenient to install and implement.

[0004] At the same time, the traditional network transparent bridge technology processes network data packets at the data link layer, which prevents a large number of network services provided by the operating system from being utilized. If these network services originally provided by the operating system cannot be effectively utilized If the corresponding service is redesigned, on the one hand, the development efficiency will be low, and at the same time, the stability of the product will not be effectively guaranteed.

On the other hand, as network applications become more and more complex, there is no way to meet all network application requirements only at the data link layer, so the application field of traditional network transparent bridge technology is very limited
