Política de Escalonamento para Servidores Web baseada na Velocidade da Conexão

Cristina Duarte MurtaTarcísio Paulo Corlassoli

This paper shows a new scheduling policy for the processing of static HTTP requests in Web servers. This policy, called FCF (Fastest Connection First), gives priority to HTTP requests based on the size of the requested file and on the speed of the user's connection. The requests for smaller files through faster connections receive the highest priorities. The motivation of this proposal is the variability of the file sizes transferred in the Web, the diversity of the effective bandwidth of the user's connection observed in the Internet and the possibility of knowing the size of the process in advance. The results show evidences that the different levels of connectivity of the Internet users affect the performance of the Web server, and that this information can be used to improve the performance of the system.
