Abstract: In order to achieve path diversity for dual-homed User-Network Interface clients connected to a Generalized Multiprotocol Label Switching control plane enabled transport network that is operated in an overlay mode, the overlay extension service model is enhanced by adding shared constraint information for path diversity in the optical transport network. In particular, within the provider network, shared constraint information of a first traffic path is determined and a data element indicative of the shared constraint information is returned by a first provider edge node to a customer edge device via a User-Network Interface. When the customer edge device requests a second traffic path through the provider network to be established from a second provider edge node and to be disjoint from said first traffic path, the customer edge device forwards the data element to the second provider edge node to enable path calculation of the second traffic path using the shared constraint information as exclusion list.

Abstract: Virtual connection route selection apparatus and techniques are disclosed. At a communication traffic routing apparatus, metric information associated with multiple different routes for a virtual connection, such as a PseudoWire, toward a destination is collected. The metric information may be collected from one or more remote route computation elements capable of computing routes for virtual connections between the routing apparatus and other routing apparatus over an underlying communication system, or during actual establishment of the virtual connections, for example. An initial or re-optimized route for a virtual connection can then be selected at the routing apparatus based on the collected metric information. In some embodiments, although the virtual connection routes are paths computed by Path Computation Elements (PCEs), actual path selection decisions are distributed to routers.

Abstract: An optical transport system is configured to use a modulation scheme in which a phase rotation applied to a sequence of PSK or QAM constellation symbols encoding a codeword of an FEC code produces a modified sequence of PSK or QAM constellation symbols encoding a bit-word that is not a valid codeword of that FEC code. Based on this property of the modulation scheme, an optical receiver may be configured to relatively accurately recover the absolute phase of the optical carrier wave of the received modulated optical signal by applying maximum likelihood sequence estimation processing to each portion of the signal carrying a valid codeword of the FEC code. For example, for a modulation scheme employing a 2n-PSK constellation, the optical receiver may be able to recover the absolute phase of the optical carrier wave with an accuracy that is better than 360/2n degrees.
