Multicast Discovery Based On P2p Ftp Server And Ftp Scheduling Optimization

As one of the most important protocols in web applications, FTP has been widely used since it was first proposed in the 1970s. P2P has seen rapid development in recent years and has gained its own advantages on internet resource sharing.FTP server software was originally designed for special servers and personal FTP servers have not been given enough consideration. But as computer hardware and software developing, more and more small scaled enterprises and personal FTP servers are set up. This paper introduces the technology of IP Multicase Discovery into the design of FTP servers which enables the automatic discovery and resource sharing and thus meets the requirement of combining multiple FTP servers for FTP service.In addition, previously designed FTP servers rarely considered, the problem of FTP Scheduling. This paper proposes a new FTP scheduling technique-Highest Response Ratio Next Dynamic Scheduling. The essence of this proposition is to "give higher prioritie to smaller file-transefer, while considering the equity principle", so that FTP servers can be utilized more efficiently.
