Abstract
Assured Service is a service model that can be offered within Internet Differentiated Services (Diff-Serv) architecture. It provides a statistical bandwidth guarantee to its subscribers, and allows the subscribers to claim a share of the excess network bandwidth in addition to the subscribed bandwidth. Recently, it has been observed that Assured Service does not meet the bandwidth guarantee for high-profile flows in the presence of numerous low-profile flows (such as best-effort). In this paper, we demonstrate that there is an inadequacy in the packet differentiation algorithm used in the Diff-Serv routers, RIO (`RED with In and Out'), that contributes to the problem. We propose a modified RIO algorithm called RI+O to reduce the effect, and show that it significantly alleviates the problem. Our approach of modifying a router algorithm incurs much less deployment cost than other approaches.
