ABSTRACT:
A method for transmitting traffic in an optical network includes establishing a light-trail in the optical network between a number of nodes. The light-trail couples the nodes and is associated with one of a number of wavelengths in the network. The method also includes, at one or more of the nodes, receiving traffic from one or more client devices of the node to be communicated over the light-trail to a destination node and determining one or more service types associated with the received traffic. Furthermore, the method includes determining traffic shaping information for each service type based on information relating to the arrival of traffic associated with the service type at the node. The traffic shaping information indicating to the destination node the rate at which the traffic associated with each service type should be communicated from the destination node to one or more client devices of the destination node. In addition, the method includes transmitting the traffic and the determined traffic shaping information for each service type to the destination node.
