摘　　要：当今的广域网传输过程中存在着大量的重复数据,这些重复数据使得广域网带宽被严重浪费。针对这一问题,提出了一种基于应用层协议识别的冗余数据消除策略。通过将数据缓存及应用层协议识别技术相结合,找出广域网传输过程中的冗余数据,尽可能使广域网中的相同数据只传输一次,从而降低冗余数据传输对广域网带宽的过度浪费。Nowadays, WAN transmission process has a lot of duplicate data, these duplicate data make bandwidth of WAN to be serious wasted. In order to solve this problem, a redundant data elimination strategy based on application layer protocol identification（PI-RE） was put forward. Using the combination of data caching and the application layer protocol identification technology, the redundant data of WAN during transmission were found out, so that the same data transferred only once in WAN as much as possible, to reduce the redundant data transmission excessive waste of WAN bandwidth.
