Resumen
Traffic conditioners play a key role in implementing the Assured Service in the framework
of the DiffServ approach. Many research papers have focused on finding the best traffic conditioner
able to assure contracted target rates and to fairly distribute the excess bandwidth among competing
sources. Nevertheless, none of the proposals presented so far accomplishes simultaneously both
features. We propose a traffic conditioner for the Internet Assured Service called Counters-Based
Modified (CBM) that strictly guarantees target rates and performs a fair share of the excess
bandwidth among TCP Reno sources. The ability of strictly providing the inbound bandwidth is
inherited from its predecessor the Counters-Based algorithm, and the fairness in the outbound
bandwidth distribution is met by probabilistically dropping OUT packets in the traffic conditioner. To
determine the dropping probability of an OUT packet, the amount of excess bandwidth and the
average RTT of all connections ...
