Publication number: 20130266315Abstract: A method and systems for implementing an access control algorithm across an optical network are described. The network includes a plurality of switch port devices, each including a local control plane processor. The local control plane processors receive control information related to the plurality of switch port devices; determine destination devices to which each of the plurality of switch port devices can transmit data and availability to receive incoming bursts at the switch port devices; and determine a time during the transmission period when the data is to be transmitted to at least one destination. Optionally, a central control plane processor receives control information from the local control plane processors and determines a time during a transmission period when at least a portion of the data is to be transmitted from at least one of the switch port devices to a destination, thereby regulating traffic over the optical network.Type: ApplicationFiled: April 4, 2012Publication date: October 10, 2013Applicant: ACCIPITER SYSTEMS, INC.Inventors: David Markham Drury, David Jeffrey Graham, Stephen Francis Bachor, Sherry Lea Kratsas, Daniel Michael Flynn
