  • SPANNING TREE FLOODING BACKBONE SYSTEMS AND METHODS FOR LINK STATE ROUTED NETWORKS
    Publication number: 20110090787
    Abstract: The present disclosure provides systems and methods for a spanning tree topology used as a “flooding backbone” for control messages on a link state routed network. Specifically, control messages are only broadcast on the flooding backbone thereby significantly reducing message flooding. The present disclosure also provides systems and methods for correctly and efficiently reconfiguring/fixing the spanning tree topology in the event of any spanning tree link failures without re-running the spanning tree protocol.

  • Systems and methods for chirp control of a dual arm z-modulator to minimize dispersion effect of fiber plant
    Patent number: 7734126
    Abstract: The present invention provides systems and methods for chirp control of a dual arm Z-modulator to minimize dispersion in the fiber plant. The chirp control is based upon a real-time control loop based upon performance monitoring data between a transmitter and a receiver. Advantageously, the present invention enables improved performance in high-speed optical systems, and in some cases can eliminate or minimize the need for external dispersion compensation fiber (DCF).
