Generalized multiprotocol label switching, also referred to as multiprotocol lambda switching, supports not only devices that perform packet switching, but also those that perform switching in the time, wavelength, and space domains. The development of GMPLS requires modifications to current signaling and routing protocols. It has also triggered the(More)
Generalized multiprotocol label switching, also referred to as multiprotocol lambda switching, is a multipurpose control plane paradigm that supports not only devices that perform packet switching, but also devices that perform switching in the time, wavelength, and space domains.

We study a special case of the problem of installing capacity on backbone networks in the presence of an uncertain traffic matrix. The uncertainty model is, in general, defined by a set of linear constraints on the traffic demands. Owing to the availability of statistics on the nominal (average) traffic matrix, in our experiments each traffic demand is(More)
Virtual Private LAN Service (VPLS), also known as Transparent LAN Service and Virtual Private Switched Network service, is a useful Service Provider offering. The service offers a Layer 2 Virtual Private Network (VPN); however, in the case of VPLS, the customers in the VPN are connected by a multipoint Ethernet LAN, in contrast to the usual Layer 2 VPNs,(More)
OSPF Traffic Engineering (TE) extensions are used to advertise TE Link State Advertisements (LSAs) containing information about TE-enabled links. The only addresses belonging to a router that are advertised in TE LSAs are the local addresses corresponding to TE-enabled links, and the local address corresponding to the Router ID. In order to allow other(More)
