Abstract:
We have developed an independent test-bed of Linux based soft routers on which experiments have been
conducted to measure Quality of Service in a Differentiated Services domain. This paper presents the first stage of
an ongoing research effort on resource management mechanisms for next-generation networks. Our current results
show proof-of-concept scenarios demonstrating how Differentiated Services expedited forwarding per-hop behavior
can be used to reduce data loss and jitter even in the presence of heavy background traffic. We propose an agent
facilitating end-to-end services by implementation of a policy-based Bandwidth Broker that is both scalable and
robust.
