Abstract: We present a model for inter-domain traffic engineering with end-to-end quality of service support, focusing particularly on bandwidth guarantees. We address the problem of egress router selection, which involves the selection of the egress router for customer traffic towards the destination prefixes taking into account end-to-end bandwidth constraints. We also consider performance optimisation in order to minimise the bandwidth consumption and achieve load balancing. Due to the computational complexity of the problem, we propose two heuristics to solve it. The simulation results show that the heuristic that involves with coordination performs better than the one without coordination, in terms of average bandwidth consumption. 1.
