| Abstract: | Proposes a new approach to implement multicast file transfer system in video conference system over the Internet based on UDP protocol. It illuminates the approach in detail,gives the communication protocols and presents a novel simple and effective method to perform broken-point continuingly-transferring.In the comparative experiments,this scheme is proved to improve data rate of transmission,occupy less network resource and be more flexible.At last,the optimization parameters are given. |
