Fast Multimedia File Transport Protocol on Embedded System
Along with the development of embedded and multimedia compression technology,embedded terminal plays a more and more important role in the high-definition media field.Due to the need of high bandwidth,high-definition media usually are downloaded first before played.Therefore,it is imperative to transmit high definition media files to embedded multimedia terminals fast and effectively via network.Based on the analysis of traditional file transport protocols and the characteristic of embedded systems,this paper proposes a new file transport protocol-EMFTP(Embedded Multimedia File Transfer Protocol).The EMFTP protocol uses a method of uniform retransmission as its error recovery strategy and adopts an improved rate control algorithm based on bandwidth probe.As the experimental result shows,comparing with UDT and FTP protocol implemented on embedded terminal,EMFTP can achieve a faster transfer rate and lower resource occupancy on embedded system.
