| Abstract(in English) | Application layer proxies, such as, content-based switches make forwarding decisions (server selections) based on an application layer information and forward data in the application layer. After making forwarding decisions, some existing proxies and most content-based switches increase their forwarding performance by TCP splicing, which releases them from maintaining TCP endpoints and allows them to forward data by packet forwarding. However, TCP splicing prevents proxies and content-switches from using the application layer information for forwarding decisions. Thus the existing content-based switches cannot hand off pipelined HTTP transactions, which can greatly reduce client perceived latencies. This paper proposes an asymmetric TCP splicing and a method to hand off HTTP transactions between servers. Asymmetric TCP splicing allows the content-based switches to use all the application layer information in the TCP data stream from clients to servers, although it allows the switches to forward the TCP data stream from servers to clients by packet forwarding. The proposed handoff method, which users a TCP half-close to detect the boundary of server responses, enables content-based switch to support pipelined HTTP transactions in combination with asymmetric TCP splicing. Our evaluation shows that if a content-based switch supports pipelined HTTP transactions by asymmetric TCP splicing and our proposed handoff method, client -perceived latencies can be reduced substantially. |
