Coexistence of Various Topology Aggregation Methods in a Hierarchical Network
Quality of Service (QoS) routing methods are expected to replace existing routing protocols in future QoS-based data networks. QoS routing allows the selection of feasible paths for connections requiring QoS support. A good QoS routing method should efficiently utilise networking resources and the overhead involved in spreading information about resource availability should be low. Topology aggregation has been proposed as a method to reduce this overhead and allow scalability to large networks. It is used in the PNNI routing protocol which has been standardised for ATM networks. There are several aggregation methods proposed by researchers. PNNI does not restrict aggregation to only one technique, stating only that: “the symmetric star topology is used as the ‘default node representation’” [1]. This paper explores the performance of PNNI routing when various aggregation methods coexist in a single network with two hierarchical levels, within a game-theoretic framework. It is...
