Admission Control of a Stateless Network: Effective Bandwidth Approach

This paper describes an admission control general framework on a packet-based Internet environment. Each application is accepted based on its effective bandwidth, bandwidth requirement and the network resources availability. This approach is applied on stateless networks, thus, the resource reservation is not required. Moreover, the core router will not distribute periodically the QoS state information. So, the network available resources will be estimated by the incoming device by means of a Local Resource Measurement. The main advantage of our proposed framework is the system scalability, because there are no extra-mechanisms to be implemented at the core routers rather than the incoming ones. Additionally, the admission mechanism avoids the QoS degradation of previously accepted applications on the network path.
