摘要： A switch node provided with a switch, an input interface and an output interface. The input interface is adapted to couple to a first communication link to receive a first TDM frame having a user payload field containing a first user data from the first communication link, and a frame overhead field containing a first identification. The input interface is configured to validate the first identification in the frame overhead field and reject the first TDM frame responsive to the first identification being invalid, and to forward the first user data to the switch responsive to the first identification being valid. The output interface is adapted to couple to a second communication link. The output interface is configured to receive the first user data from the switch, and to generate a second TDM frame having a second user payload field containing the first user data, and a second frame overhead field containing a second identification that is different from the first identification. The output interface is also configured to transmit the second TDM frame onto the second communication link.

摘要： Methods and nodes are disclosed for the support of traffic protection and recovery in mesh networks having multiple nodes communicating via communication links. The problem of timely and reliable Shared Mesh Protection message delivery is addressed through creation of protocols and encoding of Shared Mesh Protection messages within an overhead of the optical data unit container, and by processing the Shared Mesh Protection messages by intermediate nodes of the mesh network. Thus, the Shared Mesh Protection messages are transmitted through the data plane with the transmission of user data.

摘要： Methods and nodes are disclosed. In the methods, circuitry of a first node generates a link state advertising message including bandwidth information indicative of unreserved aggregate bandwidth for multiple priority connections where aggregate bandwidth is greater than available bandwidth. The link state advertising message is transmitted from the first node to a plurality of second nodes within a mesh network. Node bandwidth constraints may be established that contain some designated allocated bandwidth which is not shared with any other Class Types (CT); however, the bandwidth constraints may also allow segregation of other CTs so that within those CTs allocation of designated bandwidth is guaranteed for high priority traffic and low priority traffic is left with the remaining bandwidth in the CT's allocation.

摘要： A node may determine a failure in a first path for routing first optical network traffic between a first set of networking devices, where the first path includes a first set of optical transport nodes. The node may determine a second path for routing the first optical network traffic between the first set of networking devices, where the second path includes a second set of optical transport nodes that route second optical network traffic between a second set of networking devices. The second set of optical transport nodes may include at least one node that is not included in the first set of optical transport nodes. The node may pre-empt routing of the second optical network traffic via the second path, and may route the first optical network traffic via the second path after pre-empting routing of the second optical network traffic via the second path.
