Abstract


Currently distributed more and more enterprises , businesses and corporate headquarters branch networking among increasingly improved , most companies prefer to build a centralized data center. Centralized access to large amounts of data will inevitably lead to a decline in network performance . Affect WAN data transfer performance of the main factors are: bandwidth, application protocols and TCP / IP protocol limitations , duplication of data transmission, network latency. Most of the relevant current research focuses on one aspect of which , while these combined several techniques will greatly improve the WAN transmission performance. Accelerate the deployment of bilateral interconnection scheme is deployed , which requires a key node in the WAN edge deployments accelerate gateway , to achieve high-speed data transmission between the gateway . This paper studied the effects of WAN TCP traffic transmission performance factors discussed ACK proxy response technology, data stream caching technology in the implementation process several key technical issues. ACK proxy response programs for improved management using an embedded database management system disk cache data to improve disk processing efficiency. In the proxy response caching and data flow based on the combination of the use of combined technologies and TCP packet tunneling technology to further enhance the transmission performance of WAN solutions. Finally, in linux2.4 platform to achieve the system and detailed testing . The program can significantly accelerate TCP traffic in the WAN transmission speed , while reducing bandwidth. In FTP applications, for example , the first transmission can be increased by about 5% of the transmission speed , the re- transmission to provide 10 to 20 times the acceleration performance, while the data flow rate drops to less than half the original .
