Real time multimedia data transmission through Internet is based on UDP. The transmission must be real time and reliable. It also should be fairness with the domain protocol TCP used by other services in Internet while sharing the limited bandwidth with TCP. As networked multimedia applications become widespread, it becomes increasingly important to ensure that these applications can co exist with current TCP based applications. The TCP protocol is designed to reduce its sending rate when congestion is detected. Networked multimedia applications should exhibit similar behavior, if they wish to co exist with TCP based applications [1] . In this paper we present a simple and practical TCP friendly congestion/rate control algorithm after we comparing and analyzing a lot of congestion control algorithms, and use this algorithm in our software (FreePhone). The results of experiments show that the algorithm works well.
