  • Reliable messaging using clocks with synchronized rates
    Patent number: 7483943
    Abstract: The present invention extends to methods, systems, and computer program products for reliable messaging using clocks with synchronized rates. Embodiments of the present invention insure at-most-once delivery of messages. A source and a destination utilize clocks with synchronized rates. Messages are assigned Time-To-Live (“TTL”) values such that state information is updated the source and removed at the destination when a corresponding message timer based on a TTL value expires. Accordingly, resources consumed to maintain state information at the destination can be freed up in a shorter period of time. The source can retransmit state information to the message destination if relevant state information has been removed. Message processor instance IDs insure at-most-once delivery when a message destination suffers an involuntary memory loss. Embodiments of the present invention can also be used for exactly-once-delivery, for example, when TTL values are infinite and instance IDs are not used.

  • Discovering liveness information within a federation infrastructure
    Patent number: 7466662
    Abstract: The present invention extends to methods, systems, and computer program products for establishing and maintaining membership within a federation infrastructure. A joining node submits a join message to an existing federation infrastructure. The federation infrastructure routes the join message to a processing node. The processing node facilitates identification of predecessor, successor, neighborhood, and routing nodes (for the joining node) within a ring of nodes. The joining node exchanges messages with identified nodes to obtain state information for the identified nodes and other nodes within the ring. Nodes periodically exchange state information, including state information for other nodes, such that state information for the ring is efficiently propagated to all nodes in the ring even when communication between some nodes is lost. Instance IDs, phase values, and freshness values are used to determine when state information is stale and/or is to be updated.

  • MAINTAINING CONSISTENCY WITHIN A FEDERATION INFRASTRUCTURE
    Publication number: 20080288659
    Abstract: The present invention extends to methods, systems, and computer program products for a joining node to join a ring of nodes within a rendezvous federation. Embodiments include detecting a neighborhood of nodes on the ring of nodes. The joining node indicates its intent to take id-space ownership for a portion of the id-space between the joining node and a selected immediately adjacent node. The joining node indicates an intent to monitor the selected node. The joining node receives three indications, the first indicating acceptance of the joining node's intent to take id-space ownership for a portion of the id-space between the joining node and the selected node, the second indicating acceptance of the joining node's intent to monitor the selected node, the third indicating the first selected node's intent to monitor the joining node. The joining node indicates acceptance of the selected node's intent to monitor the joining node.

  • DATA CONSISTENCY WITHIN A FEDERATION INFRASTRUCTURE
    Publication number: 20080288646
    Abstract: In some embodiments, it is determined that a primary node has been elected from among a plurality of nodes in a replica set of nodes. The primary node accepts and processes client data access requests. The replica set includes the primary node and other secondary nodes. The primary node receives client data access requests. The primary node assigns a data sequence number to each client data access request that mutates state in the order the client data access requests are received. The data sequence numbers include a linearized processing order that is to be followed by each of the nodes in the replica set. The primary node sends the mutating client data access requests including any corresponding data sequence numbers to the secondary nodes. The primary node receives, from a threshold number of secondary nodes, an acknowledgement indicating reception of the client data access request. The primary node commits the data mutating access request.

  • Type extensions to web services description language
    Patent number: 7386860
    Abstract: A web service description language with object extensions provides type-centric extensions to web service description languages in order to describe and implement a type-centric, object-model agnostic, web service description. By implementing the constructs described herein, a heterogeneous distributed computing environment can implement rich type-centric services. For example, in a graph description, a type description indicates whether a type is encoded as a reference or embedded within another type. In a service reference description, a type description indicates whether a type is remoted by value or by reference. A type description indicates that a service extends another service, a service implements an interface (potentially multiple interfaces), a field of a type (including interfaces) is a reference type, a constant value field, or a bit field type that defines enumerations with associated values.
