Esse trabalho pretende explorar e comparar o custo da captura de pacotes e ambientes de virtualização como o Xen.

A totalizaçao desse custo pemite observar o desempenho desse tipo de solução para a alocação de serviços em redes. Além disso, esse estudo permite observar os principais gargalos do sistema, possibilitando assim a sugestões de melhorias que podem ser benéficas para o sistema como um todo.
