AB - Recent demands for new applications are giving rise
to an increasing need of Quality of Service (QoS).
Nowadays, most IP-based networks tend to use the
DiffServ architecture to provide end-to-end QoS.
Traffic conditioners are a key element in the
deployment of DiffServ. In this paper, we introduce a
new approach for traffic conditioning based on feedback
signaling among boundary nodes and traffic
conditioners. This new approach is intended to provide
a poportional distribution of excess bandwidth to endusers.
We evaluate through extensive simulations the
performance of our proposal in terms of final
throughput, considering contracted target rates and
distribution of spare bandwidth. Results show a high
level of fairness in the excess bandwidth allocation
among TCP sources under different network
conditions.
