06 Mar 2011TL;DR: This work demonstrates a converged OpenFlow enabled packet-circuit network, where circuit flow properties provide differential treatment to dynamically aggregated packet flows for voice, video and web traffic.
Abstract: We demonstrate a converged OpenFlow enabled packet-circuit network, where circuit flow properties (guarantee d bandwidth, low latency, low jitter, bandwidth-on-demand, fast recovery) provide differential treatment to dynamically aggregated packet flows for voice, video and web traffic.

08 Apr 2008TL;DR: In this article, a remodulating channel selector for a wavelength division multiplexed optical communication system is presented. But the selection of the optical channel is not a trivial task, since the wavelength of the output optical signal can be the same as or different from the optical channels which comprise the input signal.
Abstract: The present invention provides a remodulating channel selector for a wavelength division multiplexed optical communication system. The remodulating selector receives a WDM input signal, selects a particular optical channel from the WDM signal and places the information from the selected signal onto a newly-generated optical output signal. The wavelength of the output optical signal can be the same as or different from one of the optical channels which comprises the WDM input signal. When used in a WDM optical communication system with remodulators at the transmission input, the remodulating selectors provide complete control over the interfaces with optical transmitters and receivers, permitting use with a broad range of optical equipment.

27 Jul 2000TL;DR: In this article, a distributed method and system of controlling a communications network having a plurality of spans of interconnected network elements some of which include a network element processor distributes network topology information to respective span databases; stores original fault objects in the respective span database; advertises fault objects to other network element processors in a local span when the original fault affects network elements other than the network element in which the fault occurred.
Abstract: A distributed method and system of controlling a communications network having a plurality of spans of interconnected network elements some of which include a network element processor distributes network topology information to respective span databases; stores original fault objects in the respective span databases; advertises fault objects to other network element processors in a local span when the original fault affects network elements other than a network element in which the fault occurred; advertises alarm objects to other network element processors that are respectively associated with a circuit affected by the original faults; stores the advertised fault and alarm objects in the respective span databases; and performs distributed processing of the advertised fault and alarm objects with the other network element processors and the respective span databases. Aggregation of other faults and alarms that may be occurring on the communications network due to other faults other than the received fault aids in determining causality of the fault. Causality may be determined by correlating other faults and alarms with the received fault. If not a root cause of another fault or alarm, the received fault is sympathetic to another fault or alarm. Sympathetic faults are suppressed while root cause faults are promoted to an alarm and reported to affected network elements. The number of alarms viewed by a network manager as well as the reporting of alarms and underlying faults are reduced by performing such distributed alarm correlation and fault reporting suppression.

01 Sep 2012TL;DR: In this paper, the authors discuss how enhancing flexibility of coherent transceivers enables dynamic optimization of DWDM signal characteristics to extract more capacity from optical networks, and propose a coherent transceiver architecture for high capacity optical transmission systems.
Abstract: The introduction of coherent transceivers in high capacity optical transmission systems has dramatically increased networking capabilities. We discuss how enhancing flexibility of these transceivers enables dynamic optimization of DWDM signal characteristics to extract more capacity from optical networks.

07 Mar 2007TL;DR: In this article, a frequency-agile optical transceiver includes a shared local oscillator (LO), a coherent optical receiver and an optical transmitter, which operates to generate a respective LO optical signal having a predetermined LO wavelength.
Abstract: A frequency-agile optical transceiver includes a shared local oscillator (LO), a coherent optical receiver and an optical transmitter. The LO operates to generate a respective LO optical signal having a predetermined LO wavelength. The coherent optical receiver is operatively coupled to the LO, and uses the LO signal to selectively receive traffic of an arbitrary target channel of an inbound broadband optical signal. The optical transmitter is also operatively coupled to the LO, and uses the LO to generate an outbound optical channel signal having a respective outbound channel wavelength corresponding to the LO wavelength.
