TCS Overview

FIGURE 9 Logical representation of transparent caching

Four cache servers, server1, server2 server3 and server4, are installed within the network to

handle the transparent caching of HTTP traffic. Server1 and server 2 are IPv4 cache servers and

server3 and server4 are IPv6 cache servers. TCS is enabled on the ServerIron ADX to direct all

HTTP traffic to the cache servers for processing.

A ServerIron ADX or backbone switch operating as a transparent cache switch detects and

forwards all HTTP traffic to an available cache server. IPv4 HTTP traffic is directed to the IPv4 cache

servers and IPv6 HTTP traffic is directed to the IPv6 cache servers.The cache server then

processes the query and forwards the response back to the user through the attached ServerIron

ADX.
