Abstract: A method for routing traffic between a source node and a destination node in a network comprises: identifying a first group level at which a source group vector and a destination group vector differ; obtaining one or more first route segments between a first source group and a first destination group at the first group level; computing an end-to-end route between the source node and the destination node based on at least the one or more first route segments; and routing traffic between the source node and the destination node on the end-to-end route.

Abstract: An application specific interface (AA-NAPI) associated with an application for the purpose of controlling the networking aspects of the application session is provided by communication service provider (CSP). Cost model of network service types associated with a specific application type is learned by using the AA-NAPI. For each service-point joining the session, network properties are queried by using the AA-NAPI. During continuous service quality monitoring, upon detection of quality degradation leading to the decision to upgrade session quality, network service-type associated with a specific server-point is changed by using the AA-NAPI. Network specific actions are taken to reconfigure the network so that the requested service type is received by the specific service-point. New network capability is activated to improve network service level by using the AA-NAPI. Network specific actions are taken by the network to install new network capabilities so that the specific service-point's service quality is improved as requested.

Abstract: A first optical node is configured for deployment in an optical network including second optical nodes having a ring topology. The first optical node includes an optical encoder and a decoder. The optical encoder is configured to form a third optical signal for transmission into the optical network by combining a first optical signal generated by the first optical node with a second optical signal received by the first optical node from the second optical nodes. The decoder is configured to extract information from fourth optical signals received from the second optical nodes. In some cases, the first optical node includes a receive buffer configured to store information representative of the fourth optical signals received from the second optical nodes and a transmit buffer configured to store information used to generate the first optical signal.
