  • Portable universal serial bus memory devices and methods for using such devices
    Patent number: 7555582
    Abstract: Portable USB memory modules or devices and methods for using such devices are disclosed herein. In one embodiment, a portable memory module can include a housing having a CompactFlash card form factor and one or more flash memory devices carried by the housing. The portable memory module can also include a USB controller carried by the housing and coupled to the one or more flash memory devices. The portable memory module can further include a connector including a first portion coupled to the controller and a second portion configured to mate with a host device. In several embodiments, the connector includes a plurality of pins to transfer signals to and from the memory module. The pins are configured to mate with a fifty pin socket on the host device.

  • Switched token ring over ISL (TR-ISL) network
    Patent number: 6704318
    Abstract: A technique efficiently transports token ring (TR) frames over trunks interconnecting switches of a distributed TR bridge. The TR bridge is characterized by a logical switch fabric that is distributed among the interconnected switches by the trunks, which are preferably interswitch link (ISL) trunks. Each switch includes a Bridge Relay Function (BRF) coupled to a plurality of Concentrator Relay Functions (CRFs) having a plurality of ports for receiving TR frames over TR segments. The BRF and CRF of the distributed TR bridge operate according to a 2-tier switching model wherein each CRF and BRF is assigned an individual virtual local area network identifier. The technique encapsulates the TR frames in a TR-ISL protocol format that accomodates differences in formats of various TR frames and that comports with the 2-tier switching model of the distributed TR bridge.

  • Token ring bridge distributed in a switched fabric
    Patent number: 6563832
    Abstract: A distributed token ring (TR) bridge has a logical switch fabric that is distributed over a TR switching network of switches interconnected by trunk links. The distributed TR bridge includes a plurality of TR switches, each having a Bridge Relay Function (BRF) logically coupled to at least one Concentrator Relay Function (CRF). Distribution of the switch fabric essentially comprises logically distributing the BRF function among the network of switches.
