摘要： The present application provides methods of determining bandwidth demands and allocating bandwidth for a network including a plurality of groups of sub-networks. Each subnetwork includes a plurality of server racks and an aggregation switch node configured to control the flow of traffic to and from the plurality of server racks in the subnetwork. The aggregation switch nodes in the network are optically coupled to one another via at least one switch controlled by a switch controller. Each group of subnetworks of the plurality of groups of subnetworks also includes a group controller in communication with each of the aggregation switch nodes in the group. The group controllers are communicatively coupled to one another. The interaction between the aggregation switch nodes, the group controllers and the switch controllers enable distributed and dynamic control of switching between the subnetworks.

摘要： Aspects of the disclosure involve a source node, having some predetermined knowledge of the optical network generating a list of nodes and/or optical links between nodes that form a route in the optical network from the source node to the destination node. The nodes in the optical network do not necessarily need to know the entire route from source node to destination node. Each node simply decodes the control information identifying the next hop in the route towards the destination node. By utilizing the decoded control information identifying the next hop, a switch in the node can be controlled to route the optical signal including the payload and some or all of the control information onto the next optical link toward the destination node.

摘要： A system and method for obfuscating an optical signal is disclosed. Obfuscating the optical signal may make it more difficult for the optical signal to be detected by an interloper. In one embodiment, an optical signal is received at an optical transmitter, and an obfuscated optical signal is generated by performing a modification of the received optical signal. The obfuscated optical signal is then transmitted from the optical transmitter to an optical receiver. An at least partially deobfuscated optical signal is generated at the optical receiver by performing a modification of the obfuscated optical signal. The modification performed at the optical receiver corresponds to the modification performed at the optical transmitter.

摘要： Methods and apparatus for add-drop multiplexing in all optical networking are provided. A tunable optical filter is controlled to drop a first portion of an incoming optical signal in a first wavelength band and pass a second portion of the incoming optical signal in a second wavelength band. The dropped first portion is distributed among local drop optical output ports with a demultiplexer. A multiplexer combines local add optical input signals in a third wavelength band into an add optical input signal and the tunable optical filter is controlled to add the add optical input signal to the passed second portion of the incoming optical signal. The tunable optical filter is configured to lower an optical loss for the passed second portion of the incoming optical signal at the account of a corresponding increase of an optical loss in the dropped first portion and/or the add optical input signal.
