  • Link auto-configuration protocol specification topology
    Patent number: 6510141
    Abstract: The link auto-configuration protocol detects the topology of a dynamic synchronous transfer mode (DTM) architecture, detects and translates MAC addresses and negotiates configuration parameters in the DTM topology. The link auto-configuration protocol has at least three phases including a detect phase to detect information about the nodes in the network, an announcement phase to provide and negotiate configuration parameters with the nodes in the network and a commit phase to commit the nodes to the configuration parameters. The protocol may automatically switch between ring and bus topology configurations.

  • Backplane architecture for dynamic synchronous transfer mode
    Patent number: 6320863
    Abstract: A backplane for a dynamic synchronous transfer mode network that comprises two dual ring topologies having opposite fiber direction. The ring topologies has a plurality of disjointed segments that permits the simultaneous transmission of signals in the same time slots over the disjointed segments.
