Operation of transparent cache switching
A sample Transparent Cache Switching network diagram utilizing Brocade ServerIron ADX is shown
in Figure 9.
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.
