Within the ITU-T next generation network (NGN) architecture, the resource admission control function (RACF) has been designated to perform the application-driven QoS control across both access and core networks. However, an actual RACF implementation acting on MPLS metro-core networks does not exist since RACF lacks of the capability to configure QoS policies on MPLS network nodes. This prevents an...
This paper proposes a novel traffic engineering technique for layer-1 bandwidth on demand service; it offers flexible resource allocation and path provision. Evaluation results in a real network are reported.
Multicast traffic engineering (TE) has recently attracted significant attention given the emergence of point-to-multipoint multimedia content delivery over the Internet. Existing multicast resource provisioning solutions tend to use explicit-routing based TE with multiprotocol label switching (MPLS) tunnels. In this paper, we shift away from this overlay approach and address native IP multicast traffic...
