摘要： A method of extending the control plane to a network edge for a network having first set of nodes of the network are designated as core nodes, each core node being operable to route subscriber traffic between a pair of neighbour core nodes and a second set of control-plane enabled nodes of the network designated as tail nodes, each tail node connected to a core node and operating only as a source or sink of subscriber traffic. Each core node that is connected to at least one tail node is designated as a host node. The host node is controlled to advertise summary information of its connected tail nodes to other core and tail nodes in the network, thus making it possible to extend control plane function to the tail nodes which can calculate connection routes, set-up/tear-down connections and perform connection failure recovery functions.

摘要： A method and system for routing a connection on a communication network. A first bandwidth pool is classified as a long lived bandwidth pool and a second bandwidth pool is classified as a short lived bandwidth pool. The long lived bandwidth pool is used to route connections having a duration that are expected to equal or exceed a predetermined time. The short lived bandwidth pool is used to route connections having a duration that are not expected to exceed the predetermined time. A request to route a connection on the communication network is received. At least one characteristic of the connection is determined and is used to determine whether to route the connection on the long lived bandwidth pool or short lived bandwidth pool.

摘要： A method of reconfiguring a network having a transport plane for carrying subscriber traffic flows within end-to-end connections, a control plane for managing at least a portion of resources of the transport plane allocated to each connection, and a management plane for implementing management functions in the control plane and any resources of the transport plane that are not managed by the control plane. The method comprises installing an updated version of a control plane name space for a target node of the network. For each connection traversing the target node: a control plane to management plane migration is performed for removing connection state in the control plane associated with the connection, so as to transfer ownership of the connection from the control plane to the management plane; followed by a management plane to control plane migration for installing new connection state in the control plane associated with the connection, so as to transfer ownership of the connection from the management plant to the control plane, the new connection state being defined using the updated version of the control plane name space.

摘要： The invention is directed to optimizing setup of a VCAT connections using (largest) CCAT containers so as to minimize the number of cross-connection commands needed to enable data transfer. A system and method are provided for enhancing VCAT networks to include faster service restoration rates and faster connection setup times. One embodiment includes expanding available VCAT timeslots to include available CCAT timeslots. A routing and signaling control module alerts a source network element, internal network elements and a destination network element that the data transmission includes VCAT payloads rather than the expected CCAT payloads. By issuing this alert, the routing and signaling control module instructs an end-point monitoring function to overlook any mismatch between the expected CCAT rate and the received VCAT traffic. Otherwise, if the mismatch is not overlooked, then the end-point monitoring function will squelch the received VCAT traffic, which terminates the data communication.

摘要： A resilient virtual Ethernet ring has nodes interconnected by working and protection paths. If a span fails, the two nodes immediately on either side of the failure are cross-connected to fold the ring. Working-path traffic is cross-connected onto the protection path at the first of the two nodes and is then cross-connected back onto the working path at the second of the two nodes so that traffic always ingresses and egresses the ring from the working path. A traffic originating node, upon determining that transmitted packets are being looped back due to a fault on a primary path, is adapted to switch transmission of data packets from the primary path to a secondary path.

摘要： A method, a network element, and a network include determining excess margin relative to margin needed to insure performance at a nominal guaranteed rate associated with a flexible optical modem configured to communicate over an optical link; causing the flexible optical modem to consume most or all of the excess margin, wherein the capacity increased above the nominal guaranteed rate includes excess capacity; and mapping the excess capacity to one or more logical interfaces for use by a management system, management plane, and/or control plane. The logical interfaces can advantageously be used by the management system, management plane, and/or control plane as one of restoration bandwidth or short-lived bandwidth-on-demand (BOD) connections, such as sub-network connections (SNCs) or label switched paths (LSPs).
