  • Patent number: 7356529
    Abstract: An improved inter-module communication facilitation mechanism (CFM) is disclosed, which provides improved scalability, improved efficiency, and enhanced functionality and performance. In one aspect, the CFM enables a subscriber to subscribe to multiple events using a single namespace specification and a single subscription request. In another aspect, the CFM enables publishers to broadcast, rather than unicast, events to multiple subscribers concurrently. In yet another aspect, the CFM enables message exchange between senders and recipients to be conducted reliably, while at the same time ensuring that a message will be delivered to a recipient at most once. These and other aspects give rise to the many benefits offered by the CFM.
    Type: Grant

  • Patent number: 7020796
    Abstract: A high availability communication system is disclosed having multiple layers of redundancy, including network interface redundancy, network switching mechanism redundancy, and functional redundancy. To minimize the effect of the redundancy on other parts of an overall system, virtual addresses are implemented. These virtual addresses enable other parts of the overall system to interact with the communication system without knowing the details of the redundancy. By implementing multiple layers of redundancy with virtual addresses in this manner, high availability is achieved without causing inefficiencies to be suffered by other parts of the overall system.
