As a brief overview, subscribed content sources activate a surrogate placed near a network border using a protocol based on NECP (Network Element Control Protocol). The surrogate then activates an overlay network, which uses standard IBGP and GRE tunnels to ensure that it is part of the data path for new requests for content.

This system is designed to reduce both load on content servers and on the networks hosting those servers. The presenters will discuss both how an outward-facing proxy's focus on data already known to be popular can improve cache performance and present data for the specific cache replacement policies which have been tested.
