基于多协议的端口转发技术研究

Research of the Multi-protocol Port Forwarding Technology

针对快速路由器转发技术需求,提出了一种多协议端口转发技术(Multi-Protocol Label Switching,MPPF)。该技术采用多跳传输方式,其工作过程包括形成端口队列、形成端口转发表、发送Hello报文和封装端口转发报文。提出方法通过端口队列实现IP数据包的快速转发,大大减少了数据包的传输延时,同时还具有可用性、可靠性和安全性。与传统路由转发技术和MPLS(Multi-protocol Port Forwarding)相比,MPPF在大型网络中有更高的转发效率和更好的传输性能。

For requirements of the fast router forwarding technology, a technology of multi-protocol port forwarding （MPPF） is proposed. It uses the multi-hop transmission mode and includes four phases： forming port queues, forming port based forwarding tables, sending Hello packets and encapsulating port based forwarding packets. The proposed method implements fast forwarding by using port queues, which reduces the transmission delay of packets greatly. It also has the usability, reliability, and security. Compared with the traditional routing forwarding technology and MPLS, the MPPF has higher efficiency and better transmission performance in the large network.
