Research On CIFS Accelerate Between Gateways

Economic globalization leads to more and more branches of enterprise, in order tostrengthen the enterprise the data exchange between branches and headquarters, and tomeet the office of information needs, more and more enterprises begin to use wide areanetwork transmission. But because of the wide area network bandwidth, transmissiondelay and other factors, the WAN service unsatisfactory. Therefore the WAN transmissionperformance receives much attention. The current Wan acceleration performance relatedresearch mainly concentrates in the transport layer protocol optimization, however actualapplication shows: transport layer optimization for specific application protocolperformance promotion success. This article mainly concentrates in application protocol’scharacteristic, considers a variety of programmes superposition effect, to design Wanacceleration scheme.This research is based on the deployment of wide area networks to accelerate, namelyit is necessary to deploy application acceleration gateway in wide area network edge node,this paper aims to achieve the high-speed data transmission of wide area networks of CIFSapplication. This paper describes the main Wan acceleration technology implementationdetails and classification, analyszes the existing transport layer protocol and theapplication layer protocol of CIFS in the WAN transmission efficiency limitations byexperimental testing. This paper analyzes the CIFS protocol factors which are notsuitable for wide area network high delay. Then on this basis, this paper puts forward theaccelerated program which combines the features of CIFS protocol data prefetching andtunnel reusing technology.Finally, the performance of the acceleration system is analysed detailedly. This designscheme can significantly speed up the CIFS communication in WANs and reducingbandwidth usage.
