Abstract
A network element of a transport network has three fabrics housed within a single shelf of a telco rack, namely a packet fabric, an electrical fabric and an optical fabric. A stream of traffic including a plurality of lambdas is received at a trunk interface of such a shelf. The optical fabric in the shelf performs optical switching on the stream to replace a first lambda in the stream with a second lambda. The first lambda is converted within the shelf into an electrical signal. Also within the shelf, first frames are recovered from the electrical signal. The packet fabric in the shelf is used to perform packet switching on the first frames to generate a flow of second frames. The flow of second frames is transmitted at a client interface of the shelf.

21. A node in transport network, the node comprising:
-
one or more service interfaces each interfacing traffic; a packet fabric adapted to perform packet switching of the traffic, wherein the packet fabric is communicatively coupled to the one or more service interfaces; and an interface communicatively coupled to a network controller external from the node which is adapted to provision the traffic through the transport network at the node via the packet fabric, wherein the network controller is adapted to determine a path for the traffic and make associated forwarding entries at the node based on the determined path. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method in a node in transport network, the method comprising:
-
interfacing traffic via one or more service interfaces associated with the node; receiving provisioning data for the traffic from a network controller external from the node, wherein the network controller is adapted to determine a path for the traffic and make associated forwarding entries at the node based on the determined path; and performing packet switching of the traffic via a packet fabric communicatively coupled to the one or more service interfaces, wherein the packet fabric performs the packet switching based on the associated forwarding entries from the network controller. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39)

40. A transport network supporting traffic provisioned by a network controller, the transport network comprising:
-
a plurality of nodes, wherein each of the plurality of nodes comprise a packet fabric adapted to perform packet switching of the traffic; and a network controller communicatively coupled to the plurality of nodes; wherein the network controller is adapted to provision the traffic through the transport network via the packet fabric at each of the plurality of nodes, wherein the network controller is adapted to determine a path for the traffic and make associated forwarding entries at associated nodes of the plurality of nodes based on the determined path.
