Abstract

This paper deals with the problem of congestion control in a next-generation heterogeneous network scenario. The algorithm runs in the ‘edge’ routers (the routers collecting the traffic between two different networks) with the aim of avoiding congestion in both the network and the edge routers. The proposed algorithm extends congestion control algorithms based on the Smith’s principle: i) the controller, by exploiting on-line estimates via probe packets, adapts to the delay and rate variations; ii) the controller assures robust stability in the presence of time-varying delays.
