UDP OVER TCP TUNNEL

摘要

A system transports a plurality of UDP datagrams from a sending application to a receiving application by creating a TCP tunnel between a TCP sending-end and a TCP receiving-end, encapsulating the datagrams in TCP packets at the TCP transmitting-end, transmitting the TCP packets via the TCP tunnel to the TCP receiving-end over a network using a TCP/IP protocol, and extracting the datagrams from the TCP packet and forwarding the extracted datagrams to the receiving application. The TCP tunnel may provide the same delay and responsiveness as UDP protocol. The TCP receiving-end may detect when a packet is missing and request retransmission when a packet is missing, so that the TCP sending-end retransmits the missing packets. The transmitting of TCP packets to the TCP receiving-end continues when the receiving-end detects a missing packet, so that there is no lag in the forwarding of the extracted datagrams. Retransmitted packets may be discarded.

1. A method of transporting a plurality of UDP datagrams from a sending application to a receiving application over a network, said method comprising:
creating a TCP tunnel between a TCP sending-end and a TCP receiving-end; encapsulating said datagram in TCP packets at said TCP transmitting-end; transmitting said TCP packets via said TCP tunnel to said TCP receiving-end over said network using a TCP/IP protocol; and extracting said datagrams from said TCP packet and forwarding the extracted datagrams to the receiving application.
