Abstract
The Counters-Based Modified (CBM) traffic conditioner
was presented in a previous work as a feasible election for
the Assured Service implementation with DiffServ. In this
work, we evaluate the end-to-end performance of TCP Reno
sources with the CBM traffic conditioner in topologies with
one and three network nodes under miscellaneous
characteristics, i. e. variable contracted target rates and
round trip times. In addition and for the same scenarios,
the robustness of the couple CBM-RIO is tested when
Assured Service and best-effort sources coexist and
compete for network resources. Strong assurance of
achieving target bandwidths and even allocation of spare
bandwidth across different flows can be provided as shown
in simulation results.
