  • Method and system for router redundancy in a wide area network
    Patent number: 7554903
    Abstract: A method for selecting an active router in a communication device includes providing multiple routers in the device, coupling the routers to a single physical link, monitoring a status for each of the routers, and selecting one of the routers as an active router by positioning its corresponding relay.
    Type: Grant

  • System and method for monitoring noise associated with a communication link
    Patent number: 7453900
    Abstract: A method for monitoring noise associated with a communication link is provided that includes monitoring a plurality of communication links that facilitate a plurality of communication flows and determining whether an error parameter associated with a selected one or more of the communication links has exceeded a predefined threshold. An alert message may then be communicated to a next destination when the predefined threshold has been exceeded.

  • Method of controlling TWA link in a communications adapter by monitoring buffer fill levels
    Patent number: 5377184
    Abstract: A communications adapter interconnects a first device exhibiting a two way alternate (TWA) protocol and a second device exhibiting a two way simultaneous (TWS) protocol. The communications adapter comprises a transmit buffer for storing data received from the first device via a first communication link for transmission to the second device via a second communication link, and a receive buffer for storing data received from the second device via the second communication link for transmission to the first device via the first communication link. Data can be transferred in either direction between the transmit or receive buffer and the first device faster than in the same direction between the transmit or receive buffer and the second device.
