Abstract: In one embodiment, a method includes receiving at a network device, route convergence measurements and traffic demand measurements from a plurality of routers, and computing network availability based on the measurements at the network device. The route convergence measurements are associated with route computations at the routers and the traffic demand measurements include portions of a demand matrix associated with the routers. An apparatus and logic are also disclosed herein.

Abstract: Packets are encapsulated and sent from a service node to an application node for applying one or more Layer-4 to Layer-7 services to the packets, with service-applied packets being returned to the service node. An identification of a virtual private network (VPN) may be carried within a request packet, encapsulating a particular packet, sent by a service node to an application node for applying a service to the particular packet; with the corresponding response packet sent to the service node including an identification of the VPN for use by the service node in forwarding the services-applied packet. Additionally, parameters may be included in a request packet to identify a particular service of a general service to be applied to a particular packet encapsulated in the request packet.

Abstract: Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means for transportation of IEEE 802.1ah frames over Multiprotocol Label Switching (MPLS) pseudowires for Virtual Private LAN Services (VPLS). The IEEE 802.1ah frames include a corresponding B-VLAN tag, while the MPLS packets including these frames do not include the corresponding B-VLAN tag, and disclosed are methods and apparatus for performing such translation.
