NETWORK SLOT SYNCHRONIZATION SCHEME FOR A COMPUTER NETWORK COMMUNICATION CHANNEL.

摘要

Synchronization within a common communication channel having designated transmission time slots for various devices of a computer network is maintained by allowing transmissions within the channel outside of a network device's designated time slot when a clear channel assessent indicates that a previous time slot is not being utilized by its associated device and/or upon receipt of an indication of the end of a tansmission of another device in the network. The clear channel assessment preferably tales into account the device's designated transmission time slot within the communication channel with respect to those of other network devies and may be a time period that is the product of a predetermined clear channel waiting time and a numerical representation of the device's designated transmission time slot within the communication channel with respect to those of other network devices. The clear channel waiting time itself may be specified by a network master device as part of network connection process. The network device may be configured to construct one or more packets for transmission within the network in advance of its designated time slot to accommodate these early transmissions.
