TWCB Configuration Example

In this TWCB configuration example we will step through the configuration of two server farms
named s1Server and s2Server. The S1Server server farm will have round‐robin predictor end‐user
ranges associated with it from both the 20.10.10.0/24 subnet and the 10.10.10.0/24 subnet, for users
with an expectation of heavy web‐site access requirements. All other users not members of a
predictor round‐robin list or denied host redirect will use the s2Server server farm with a standard
cache.
The s1Server will have cache servers 186.89.10.51 and 186.89.10.55 associated with it. The s2Server
will have cache server 196.89.10.20 associated with it. s1Server cache servers will use faildetect
type ping with faildetect parameter values changed to an interval of 4 seconds and the number of
retries to 5. The s2Server cache servers will use the application faildetect type, with faildetect
parameter values changed to an interval of 12 seconds and the number of retries to 5. The
maximum number of connections per cache server will be configured for 800 for both server
farms.
The web‐cache will be configured as cache1. The HTTP port being used has been changed from
the default of 80 to 8080. A bypass list has been configured to deny TWCB functionality for web
requests to web host sites 50.10.10.30 to 50.10.10.43 because these sites require IP address
authentication for user access. End‐users 10.10.10.25 to 10.10.10.30 have been configured to deny
TWCB functionality.
On the switch TWCB router bindings are limited to 20,000 and the TWCB cache size is limited to
5000.
