Dynamic admission control is a very important mechanism that aims, not only to check resources availability, but also to verify QoS constraints satisfaction. In this paper, we propose a new admission control mechanism in MPLS-based packet-switched networks. This admission control mechanism satisfies delay constraints for all the network connections.

In Next Generation Networks (NGN), survivability and availability are becoming more and more key features. Reliability gains more importance in high- capacity networks where IP and optical technologies have converged toward a common control plane, such as GMPLS. In most previous research works, survivability aspects were mainly limited to a single fiber(More)
Today's converged networks are mainly characterized by their support of real-time and high priority traffic requiring a certain level of Quality of Service (QoS). In this context, traffic classification and prioritization are key features in providing preferential treatments of the traffic in the core of the network. In this paper, we address the joint(More)

Quality of Service (QoS) is more and more becoming a necessity for emerging applications carried by IP networks. Thus, dynamic admission control is a very important mechanism that aims, not onlyto ensure resources availability, but also to verify QoS constraints satisfaction.
