This paper focuses on routing strategies for elastic flows within a flow-based routing architecture. In contrast to other elastic flow routing studies, we assume that elastic flows have a minimum guaranteed rate and are, therefore, subject to admission control. Our ultimate goal is to devise an adaptive algorithm that maximizes the throughput of elastic flows at light load and that preserves network efficiency under overload conditions. To this end, we examine in this paper the impact of trunk reservation on elastic flow quality of service. Trunk reservation is a technique commonly used in circuit-switched networks to prevent performance degradation under overload conditions. Two algorithms integrating a form of trunk reservation are proposed and their performance compared by means of simulation to the performance achieved by an alternative algorithm that we proposed and evaluated in an earlier study [1]. Our results highlight interesting features of trunk reservation when used for elastic flow routing.
