<p>Interfacing A Communication Network A carrier sense multiple access with collision detection strategy ascertains for a particular network configuration the network propagation time, and promulgates a parameter p providing an indication thereof to each station of the network. Each station of the network stores p for use in making decisions about collisions. Whenever a modification of the network is made changing the propagation time, a new value of p is promulgated to the stations of the network so that the collision related decisions made by each station's interface controller will reflect the new network configuration. Communications are formed in packets with a preamble long enough to propagate the network. The controllers analyze the signals they receive to discern whether a packet has been contaminated by an interference.</p> |
