Abstract :
With the explosive growth in Internet traffic, requests have been overloading Web servers. Many ISPs and search engines employ a server cluster to build a cost-effective, scalable, and reliable server system. To make such a distributed-server system transparent to clients, architects usually place a switching device with one virtual Internet protocol (VIP) address in front of the server cluster as a common interface. We designed and implemented a content-aware switch based on an ENP2611 board that contains an Intel IXP2400 network processor (NP). A content-aware switch can optimize cluster-based server architectures by examining requests and distributing them to servers on the basis of application-level information. A network-processor-based switch can reduce HTTP processing latency and improve packet throughput
