A recurring theme for server-based computing is the cost and performance impacts of bandwidth- limited WAN links. One potential solution to get the most mileage out of that WAN investment is to implement caching. Expand Networks' Enterprise Caching technology is based upon packet caching, not content caching, and is purported to be a significant performance-enhancer for Citrix ICA sessions.

Tolly Research quantified the degree to which caching improves bandwidth efficiency and also determined the specific conditions under which the technology yields meaningful performance enhancements. Those conditions include examination of the impact of application type, thin-client protocol, number of user sessions, and dependencies on the similarity of user sessions.

Tests in this issue were conducted over a simulated wide-area network (WAN) oriented to the delivery of server-based applications over bandwidth-limited links. These tests primarily are applicable to enterprise organizations, and require caching devices on both ends of the tested links. This is similar to a scenario in which a central applications server delivers enterprise applications to multiple locations.
