Abstract:
A network interface mechanism and method is provided that facilitates precise transmission time control in a computer network. The network interface mechanism and method uses feedback to provide monitoring and precise control of the transmission time. Specifically, a message detector is provided that monitors the network for transmissions from the network interface mechanism. The arrival time of messages is compared to the desired transmission time, and the transmission time of subsequent transmissions is adjusted accordingly. A transmission disable mechanism is used in the forward path to disable the transmission driver at the transmission cut off time as a means to prevent the transmission node from babbling the media. Thus, the network interface mechanism and method provide precise control of the transmission time, and thus can be used to eliminate collisions in the network. The network interface mechanism and method allows the application of Ethernet controller to have precise transmission timing control in a computer network.

Abstract:
Methods and apparatus are provided for a fail-operational global time reference for a synchronous redundant data bus including multiple pluralities of timing servers cross-coupled between a plurality of buses in said redundant synchronous data bus system, the apparatus comprising each said timing server of the multiple pluralities of timing servers configured to transmit, receive, and monitor synchronization signals, to store a unique constant, and to independently and automatically select as timing master one or more timing servers from among the multiple pluralities of timing servers based on said synchronization signals received from one or more of said timing servers of said multiple pluralities of timing servers and further based upon a relationship among said unique constants stored in each timing server. Methods comprising selection protocols are also provided.
