In order to design and implement the XMPP protocol-based file transfer module of instant communication system,it is necessary to solve such problems as NAT traversal and breakpoint continual transfer. Based on Openfire open source server,the Socks5 agent technology is used to solve the first problem; the method of adopting the uniqueness of file verification with MD5 value and recording the offset of received file with cache files is used to solve the second problem. The practical results show that the proposed file transfer module features fast and secure transmission.
