SummarySummary• Policy-based SLB allows the ServerIron to load balance incoming requeststo specific real servers based on the source IP address of the request• Concurrent persistence allows a client to make multiple successive connectionsto the same real server on multiple unknown destination ports• Sticky persistence provides the ability to load balance a client to the samereal server with which it started the session• Configurable TCP/UDP Application Groups provide the ability for a client tomake multiple successive connections (up to 4) to the same real serveron multiple predefined destination ports• Cookie switching allows the ServerIron to load balance a client to thesame real server based on the cookie the client received from the realserver• Cookie insertion allows the ServerIron to offer the client the cookieneeded (instead of the web server) for cookie switching• Cookie hashing provides the ability for the ServerIron to load balancebased on custom cookies generated by the real servers• SSL ID Based persistence load balances a client to the same SSL realserver to which the client made its initial connection• URL switching provides the ability to load balance to specific real servers(or groups of real servers) based on the contents of the requesting URL• Transparent Cache Switching provides the ability to use the speed andefficiency of cache servers without having to configure the clients• TCS is “transparent” to the client; it never has to know that its webrequest may have been forwarded to a cache server, rather than theInternet• TCS allows for up to four cache-groups with up to 254 cache servers ineach group• All interfaces are applied to cache-group 1 by default• Policy-based Caching allows you to define which destination web sitesshould never be retrieved from a cache serverBrocade IP Primer 369
Chapter 16: Session Persistence and Transparent Cache SwitchingChapter Review Questions1. All interfaces on the ServerIron are, by default, a member of cache-group:a. 2b. 5c. 1d. 32. URL switching requires defined policies to match the contents of the URL.This type of policy is called a:a. ip filterb. CSW policyc. ip policy urld. port http url3. Which persistence method provides the ability for a client to connect tothe same real server on multiple unknown destination ports?a. Stickyb. SSL ID Basedc. Concurrentd. Application Groups4. On a Brocade ServerIron, how many cache-groups may be defined?a. 4b. 3c. 8d. 05. Which keyword is used to apply defined policies to the cache servers inPolicy-based Caching?a. filter-matchb. ip filterc. cache-group 1d. keepalive370 Brocade IP Primer
