Routing Protocol of CSM Proxy Plus allows organizations to gain much greater efficiencies from their proxy servers. Proxy servers are spared the traffic congestion of ICP queries - a problem which increases which each server added to an ICP array. The efficiency of the array is preserved by avoiding duplication of content that can degrade a five-server ICP array into five independent caches holding much the same content. All of this results in the ability to deploy Proxy Server arrays that provide built-in load balancing, scalability, fault tolerance, ease of administration, and the efficiency of a single logical cache. And because CARP uses HTTP, it accomplishes this without introducing a new wire protocol.
CARP means faster response to queries, and a far more efficient use of server resources.
