Abstract:SummaryWeb caching and replication are efficient techniques for reducing Web traffic, user access latency, and server load. In this paper, we first propose an improved GreedyDual* (GD*) cache replacement algorithm, which considers update frequency as a factor in its utility function. Second, we present a group-based method for dynamically selecting distribution strategies for web documents according to access patterns. The documents are divided into groups according to access patterns and the documents in each… Show more
