Proxy Ativo: Dimuindo a Latência através de Pushing

Bruno Gusmão RochaAdriano Alonso VelosoWagner Meira Jr.Virgilio A. F. Almeida

The majority of the Internet users still access the Web via slow modem connections. Studies have shown that the limited modem bandwidth is the main contributor to the latency perceived by users. In this paper we introduce one approach to reduce the latency by pushing between proxies and its clients, in special low-bandwidth clients. The approach takes advantage of idle periods between requests to pull proxy-cached objects which will be probably accessed next by the client. We use data mining concepts to develop a efficient prediction model and evaluate the potential of this technique at reducing client latency throught simulations based on real workloads from a major proxy in Minas Gerais.
