Method, system and device for realizing TCP transparent proxy based on remote desktop protocol

Abstract

The invention provides a TCP transparent proxy implementation method, system and device based on a remote desktop protocol, and belongs to the technical field of data transmission. The method comprises the following steps: hijacking data of a graphic protocol video stream through a client, and sending the data to a server; and the server side completes TCP proxy in a seven-layer forwarding mode. According to the invention, the terminal assets are processed in a TCP transparent proxy mode during operation and maintenance. According to the method, upper layer protocols are not distinguished and researched any more, but the method is implemented by uniformly forwarding TCP layer video streams. The implementation mode can be used as a selection mode of asset operation and maintenance, namely a proxy mode. And a direct connection mode and an agent mode can be adopted for coexistence, so that operation and maintenance management of assets is more convenient.

Description

technical field [0001] The present invention relates to the technical field of data transmission, and more specifically relates to a remote desktop protocol-based TCP transparent proxy implementation method, system and device. Background technique [0002] Terminal assets are operated and maintained through the remote desktop protocol. At present, centralized session management, network protocol flow, and asset direct access are mainly used. However, since most of the applicable operation and maintenance terminals are WINDOWS system operation and maintenance terminals, with the diversification of operating systems, the existing remote desktop protocol has been unable to meet the needs of some special systems and special environments. [0003] Specifically, the existing remote desktop protocols need to be differentiated for different protocols, and some supporting software needs to be installed on the operation and maintenance terminal for implementation. Faced with differen...

Faced with different operating systems, the adaptation work is more complicated

[0004] In addition, the existing remote desktop protocols also have different degrees of defects while realizing functions: the remote desktop protocol cannot be well adapted to the special environment of the customer site

For example, the operation and maintenance and assets are in different VLANs, and the firewall policy does not support direct communication, etc.; most of the operation and maintenance assets are connected through the remote desktop protocol, and most of them use the direct communication method, which cannot perform unified management of asset operation and maintenance data, and cannot guarantee to a certain extent Data security during network transmission
