Resumo
This work presents several ways of using mechanisms of Quality of
Service (QoS) in networks hardwired for links of short band. It is
demonstrated that the use of mechanisms of QoS brings profits of performance
for priority applications and rationality in the use of band resources. The
work is developed in a test platform of Previdência Social. Implementations of
the PHBs EF, Afs and BE are tested. The work has evaluated the capacities to
offer guaranteed band, traffic priority, conditioning of traffic and the impact
of the competition between traffic classes.
The experiments are mounted using the architecture of differentiated
services (DiffServ) of platform Cisco, that is the standard in the network of the
Previdência Social and are manipulated the mechanisms of classification,
control of congestion, policing and conformation of traffic. The results give
subsidy for implementation of some models of QoS in IP networks, mainly for
those that serve short band.
