Abstract	This paper addresses the bandwidth management problem in Differentiated-Service-aware Traffic Engineering (DS-TE) architectures. In this context, Bandwidth Constraint (BC) models have to be configured to control the maximum amount of resources per traffic class per link and drive routing decisions to the fulfilment of the QoS requirements. A self-management module is implemented in each node of the network. It monitors the unreserved bandwidth in adjacent nodes and adjusts the local bandwidth constraints so as to reduce the differences in the unreserved bandwidth of neighbor nodes. Accordingly, it smoothes abrupt differences in bandwidth availability along possible paths, which are frequently due to static settings of bandwidth constraints. Due to the distributed nature of the proposed solution, the adjustments can be frequently introduced, allowing for a quick adaptation of the network to the traffic changes. The proposed solution is compared with static bandwidth constraint settings in terms of resulting bandwidth blocking rates, traffic distribution and preemption rate parameters.
