Local area network with message priority

摘要: A message priority scheme for use in local areas networks (LANS) operating accordance with carrier sense, multiple access/collision detect (CSMA/CD) bus access protocol. LAN station having a high to send ignores the sense signal, and thereby obtains immediate access. If collides another already on bus, both messages are subject backoff period. However, period is guaranteed be less than that of low certain number re-transmission attempts. An intermediate status assigned previously had status, after transmission The deprived its ability transmit while ignoring but retains shorter
