Improving HTTP caching proxy performance with TCP Tap |
| David Maltz, Pravin Bhagwat |
| Application layer proxies are an extremely popular
method for adding new services to existing network applications.
They provide backwards compatibility, centralized administration, and the
convenience of the application layer programming
environment. Since proxies act as traffic concentrators, serving multiple
clients at the same time, during peak load periods they often become performance
bottlenecks. In this paper we present an extension of the TCP
Splice technique called TCP Tap that promises to dramatically
improve the performance of a HTTP caching proxy, just as TCP Splice doubled
the throughput of an application layer firewall proxy.
