An UDP-based protocol for Internet robots

摘要

For real-time applications such as Internet robots, The UDP protocol is shown more suitable than the TCP in terms of delay and delay jitter. But uncontrolled UDP traffic may do harms to the majority TCP flows or even threaten the Internet stability. Upon a study of the data transmission characteristics of the Internet robotic applications, a novel Internet robot oriented data transmission algorithm based on the UDP protocol is introduced. The great advantage of this scheme is that extra bandwidth can be probed and caught up with adaptively within a reasonable short period of time while smoothness of sending rate is achieved. The TCP-friendliness, intra- protocol fairness and efficiency boundness of the protocol are shown in the paper.
