基于P2P技术的远程协同通信平台的设计与实现

DESIGN AND IMPLEMENTATION OF REMOTE COOPERATING COMMUNICATION SYSTEM BASED ON P2P TECHNOLOGY

由于NAT(Network Address Transformation)技术本身的设计原理,导致原本透明的端到端变的不可达。就如何不改变现有网络配置的情况下,恢复端到端的可达性,实现不同内网之间的主机穿透NAT,并在此平台上实现WWW访问、远程桌面管理等功能给出了相应的解决办法,本系统通过重新组合TCP连接的方法实现通信功能,不受防火墙等网络设备的限制,具有比传统的方法容纳更多用户的能力。

Because of the limitation of the principle of NAT, the network data cannot arrive from one host computer to the other.transparently. This paper gives how to transmit network data from one host computer to the other transparently by no any change of the network configures,it can transmit network data through different intranets which adopt the NAT technology. Based on this, it can realize many network applications between hosts which in different intranets, such as www, telnet, etc. Through afresh the TCP connecting method, the System can realize the interact communicating function that no any limitation of the equipment, such as firework, etc, and by this technology. Comparing to the traditional method, it can be used by more users.
