Resource allocation algorithms for intra-domain quality of service provisioning

Resource provisioning mechanisms play a crucial role in determining the level of quality of service offered by a network. Based on the current research activities, this paper presents a scalable and dynamic set of resource allocation mechanisms applied in the context of the AQUILA intra-domain architecture for providing QoS guarantees. We are focusing on the details of the interworking among the proposed resource allocation mechanisms, which take place at a different time-scale and are applied at different levels of the network architecture, highlighting the scalability features they convey. Finally, the presented trial results underline the performance and scalability offered by those mechanisms, which succeed in providing the expected QoS guarantees keeping simultaneously complexity and simplicity at a low level.
