摘要： A node is configured to receive an instruction to establish a channel having a bandwidth that corresponds to an operating spectrum an optical fiber; obtain information that identifies a channel spacing and a pointer that identifies where, within the spectrum, to establish bandwidth allocations; identify a group of bandwidth segments based on the spectrum and the channel spacing; and generate bit words that correspond to the bandwidth allocations, where the bit words includes bits that, when set to a value, cause sets of segments to be reserved within the spectrum, and where the sets of segments identify where the bandwidth allocations begin and end, within the spectrum, relative to the pointer.

摘要： A network device is configured to store parameters identifying a respective quality of service (QoS) to apply to corresponding different types of data flows; initiate establishment of a network channel between a source device and a destination device through an optical network; receive first and second data flows destined for the destination device, where the first data flow and the second data flow may have first and second data flow types; identify a first QoS and a different second QoS to apply to the first and second data flows based on the first and second data flow types and based on the parameters; apply the first QoS to the first data flow and the second QoS to the second data flow to form processed first and second data flows; and transmit, via the network channel, the processed first and second data flows towards the destination device.

摘要： An example method includes identifying a fault condition in a network, and evaluating pseudowires affected by the fault condition in order to make a determination as to whether an aggregate failure occurred in the network for a group of pseudowires. The method also includes communicating a group message indicating that the group of pseudowires is associated with the fault condition. The group message includes a group identification (ID), which identifies the group of pseudowires, and the group message includes a pseudowire group label identifying an in-band aggregate channel. More specifically, the pseudowire group label can be applicable to static pseudowires. In more detailed embodiments, the group ID identifies the group of pseudowires that are associated with an attachment circuit, a label switched path, or a port. Internal mappings can be maintained such that a plurality of pseudowires is mapped to individual interfaces of network elements in the network.
