ARRANGEMENT FOR ACCESSING MEDIA IN A NETWORK HAVING UNIVERSAL MULTIPLE ACCESS NODES AND CARRIER SENSE NODES |
摘要 |
A network includes a combination of carrier-sense stations and Universal Multiple Access (UMA) stations using a time slot multiple access protocol. The network is configured to include assigned time slots for the respective UMA stations and unassigned time slots reserved for the carrier-sense stations to access the shared network media. Each of the UMA stations is provided with a corresponding assigned time slot and the total number of time slots. Since the UMA stations access the media only during the assigned time slot, the carrier-sense stations can contend for access to the media after waiting a minimum interpacket gap (IPG) after sensing deassertion of the receive carrier on the media. The UMA stations may also be modified to attempt access of the media using Ethernet-compliant, carrier-sense multiple-access with collision detection (CSMA/CD) protocol when a current time slot corresponds to a mixed-use time slot.
