Abstract
Microcomputer Local Area Networks have recently become quite popular. Higher demand in term of number of users who contribute a variable amount of load has led to Multiple File servers in a LAN. As a result of variable load, response time at workstations differ significantly depending not only on total load on the network but also on workstation distribution across servers. The goal of this study is to develop schemes to keep response time as low as possible and constant among workstations. This study is based on minimizing response time and containing it or keeping it constant by distributing workstations among servers and allotting right cache memory to servers. Three allocation schemes have been suggested static ? existing now at NJIT PC lab, Dynamic and the combination of static and dynamic. Probabilistic heuristics have been formulated and evaluation has been done using queuing theory. The results indicate that combined allocation scheme gives better results as compared to other two schemes. It was inferred both dynamic and combined allocation methods have their own advantages depending on the environment. Combined allocation method runs good in educational environment type environment but dynamic allocation is more flexible and is more suited for commercial 'Real time sensitive' environment.
