    摘要: Methods, systems, and computer program products for high-performance interprocess communication. Each process dynamically identifies routines responsible for managing communication received from other processes through a shared memory heap and a shared memory queue, each of the routines handling one or more operation codes. An allocation from the shared heap produces a process agnostic memory handle from which a process specific memory pointer may be obtained. Using the memory pointer, the enqueuing process places an operation code, parameters, and any other relevant data in the allocated memory and adds the memory handle to a shared queue. The dequeuing process removes the memory handle from the queue and generates a memory pointer to access the allocated memory in the dequeuing process. Upon retrieving the operation code from the allocated memory, the dequeuing process calls the appropriate handler routine. Enqueues may be registered to account for expected responses that are not received.

    摘要: The present invention provides for a messaging system that automatically identifies a forest that corresponds to a particular recipient of a message, without using a common or unified directory that maps forests with recipients. In a network with multiple forests, each forest having multiple recipients, when a message is received at a message server with a destination address that does not uniquely identify a particular forest, the present invention provides for using a standard messaging protocol for querying each forest. The forests respond with status codes that indicate whether or not a recipient associated with the destination address corresponds to the forest being queried. If a status code indicates that the recipient corresponds to the particular forest, information may be stored and used to quarry that particular forest first, before querying other forests within the network.
