  • Bandwidth efficient multipoint data communication system
    Patent number: 4536874
    Abstract: Apparatus and method are described for a data communication network which has topological independence, low variance service time distributions, potentially guaranteed maximum time to transmit, easy expansion and high error tolerance.The network access control is fundamentally a permit (token) based system. This yields highly efficient utilization of the channel and powerful control over priorities on access to the network. In addition, a contention based scheme is provided to enable error recovery, startup, and restart to be fast and reliable.
