  • Clock synchronization in a bidirectional network
    Patent number: 8363679
    Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of Ethernet frames and/or other data across a cable transmission network or other form of FDM transport. The architecture involves downstream and upstream FDM multiplexing techniques to allow contemporaneous, parallel communications across a plurality of frequency channels. Furthermore, the architecture allows a central concentrator to support a plurality of remote devices that each has guaranteed bandwidth through connection-oriented allocations of bi-directional data flows. The upstream and downstream bandwidth allocation can support symmetrical bandwidth as well as asymmetrical bandwidth in either direction. As a local network, the architecture supports guaranteed bandwidth for delivery of data flows to a plurality of host devices.
