  • Method and apparatus for networking data devices using an uplink module
    Patent number: 5854790
    Abstract: A network (10) includes several local networks (32, 34, 36). Each local network (32, 34, 36) includes a repeater (12, 16, 20) coupled to data devices (14, 18, 22). The combination of the repeater (12, 16, 20) and the data devices (14, 18, 22) form a collision domain for managing communications within the local network (32, 34, 36). Uplink modules (40, 44) manage communications between the local networks (32, 34, 36) by isolating collision domains and generating collision indications when messages cannot be transmitted. The uplink modules (40, 44) may also implement bridging, routing, or filtering capabilities that inhibit transmission of an intra-network message beyond its local network (32, 34, 36).
    Type: Grant

    Date of Patent: December 29, 1998
    Assignee: Compaq Computer Corp.
