摘要： Systems and methods for horizontal synchronization are implemented by a first node with a second node adjacent to the first node in a network with a control plane. The horizontal synchronization manages and corrects for a state of a service which is resizable. The systems and methods include providing a first horizontal synchronization message to the second node with a first state comprising the state of the service at the node and a first size comprising a size of the service at the node; receiving a second horizontal synchronization message from the second node with a second state comprising the state of the service at the second node and a second size comprising a size of the service at the second node; detecting a mismatch of the service with the second node based on the second horizontal synchronization message; and performing a recovery action to correct the mismatch.

摘要： A method implemented by a processing device for gridless optical routing and spectrum assignment on links in an optical network includes, responsive to one or more new channel requests, performing a path computation utilizing frequency markers to determine feasibility of the one or more new channel requests, wherein the optical spectrum is represented as a real line with the frequency markers indicative of used optical spectrum; allocating the one or more new channel requests based on the path computation and allocation criteria; and responsive to allocating the one or more new channel requests, updating the associated frequency markers on the real line.

摘要： A method for bandwidth management in an optical broadcast network includes signaling, for a new optical broadcast service, from an originating node to all nodes in the optical broadcast network, wherein the signaling identifies a wavelength or portion of spectrum associated with the new optical broadcast service; at each of the nodes, checking for contention by the new optical broadcast service; responsive to identifying contention at one of the nodes, signaling the identified contention back to the originating node; and responsive to no contention at any of the nodes, processing the signaling, storing an update of the new optical broadcast service, and either forwarding the signaling to peer nodes or terminating the signaling.
