Abstract :
MPLS-TE (Multiprotocol Label Switching - Traffic Engineering) and DiffServ are technical alternatives used for supporting Traffic Engineering and QoS-demanding applications, such those typically found in multimedia multiservice networks. This paper proposes the ADAPT-RDM algorithm, suitable to allocation or not of LSPs (Label Switch Paths) according DiffServ-aware MPLS Traffic Engineering (DS-TE) and with the utilization of the RDM (Russian Doll Model) bandwidth constraint model. The principal objectives of the ADAPT-RDM algorithm are fundamentally the class types (CTs) priority preservation and the management of the bandwidth sharing capabilities of the RDM model. The paper describes the proposed algorithm and evaluates its results considering different implementation scenarios.
