Description
Bandwidth Allocation Models (BAMs) are configured in MPLS/ DS-TE networks by setting Bandwidth Constraints (BCs) for traffic classes. Effectively, BAMs define how bandwidth (resource) is used and shared by network applications. Proposed BAMs like MAM - Maximum Allocation Model, RDM - Russian Dolls Model, G-RDM - Generalized RDM and AllocTC-Sharing aim to optimize the use of bandwidth for links with different bandwidth allocation characteristics and sharing. As such, the adoption of different BAMs and/or changes in the traffic profile may result in different traffic allocation patterns and distinct operational behaviors for the network. This article analyses the impact of BAM reconfiguration in relation to network parameters and characteristics such as link utilization, preemptions and flow blocking for different traffic scenarios. Authors argue that the creation of a mechanism for smoothing the
BAMs reconfiguration process may result in benefits for network operation in terms of flow preemption and / or blocking.
