    Assignee: Ciena Corporation
    Inventors: Michael Gazier, Ian Duncan, Daniel Rivaud
  • Patent number: 8630315
    Abstract: The present disclosure relates to Ethernet synchronization systems and methods that combines Synchronous Ethernet (Sync-E) and Precision Time Protocol (PTP) IEEE 1588 algorithms. The present invention includes systems and methods for Ethernet networks and node configurations that include a set of rules on node placement, such as Boundary Clock (BC) nodes and Sync-E nodes, a clock selection algorithm, a holdover algorithm, and the like. Advantageously, the present invention provides an architecture that allows practical and real-world useful clock propagation through placement of BCs and Sync-E nodes for best performance. Practical experience and theoretical design are embodied in the present invention to define a very specific set of rules on how to build a network capable of providing accurate and reliable synchronization. The present invention includes clock selection that unifies Sync-E and 1588 algorithms.

  • Patent number: 8184526
    Abstract: The present disclosure provides systems and methods for Ethernet Connectivity Fault Management (CFM) extensions to provide a CFM messaging mechanism for support of information exchange and the like, in addition to end-to-end connectivity and fault management. In an exemplary embodiment, the present invention utilizes CFM extensions to provide Pseudowire (PW) MAC addressing. Here, the present invention can enable the exchanging of MAC addresses and other attributes for PDH pseudowire transport. Advantageously, this avoids involving the OSS/EMS/NMS in pre-provisioning these necessary but arbitrary attributes across the network elements supporting a pseudowire service. Also, the present invention can be extended to support numerous other applications involving sharing of attributes between nodes over the extensions provided herein.
