Abstract
This paper describes a new architecture that provides end-to-end QoS support, and analyses its performance in terms of QoS guarantees and scalability of the solution. This architecture introduces a scalable per-flow signalling model, using several techniques and algorithms developed in order to minimise the computational complexity. A label switching mechanism and an efficient timer implementation were developed with the goal of reducing the signalling processing overhead at each router. The underlying architecture is based on DiffServ and the resource reservation is performed for aggregates of flows at both core and access networks. The performance results presented in this paper show that this architecture is able to support both IntServ service models in high speed networks, minimizing the processing load in each network element.
