Network topology control method and apparatus.

摘要

A method and apparatus for controlling the topology of a local area network (LAN) configured as a ring of trees. The stations comprising the LAN are limited to single access stations (SAS), dual access stations (DAS), wire concentrators (WC), and DAS/WC combination stations. The topology control requires the exchange of connection type information only between immediately adjacent stations. The resulting simplicity in the information exchange requirements allows validation and rejection of invalid connections or reconfiguration of the network topology to be implemented as low as the Physical layer of the ISO model.
