摘要:
An apparatus and method allows processing sequenced records across multiple network connections. A “logical connection” is defined to include one or more network connections. Each message is assigned a sequence number that allows the messages to be ordered on the other end according to sequence number, regardless of which network connection in the logical connection is used to transfer the message. By defining messages, sequencing those messages, and transferring the messages over multiple network connections, the throughput and performance of networked computer systems are substantially increased.

An apparatus, program product and method utilize cluster data port services within a cluster infrastructure to provide reliable and efficient communications between nodes in a clustered computer system. The cluster data port services present an abstracted transport service that encapsulates and manages the establishment of multiple connection paths between a source node, a target node and one or more backup nodes in such a manner that a cluster data port is effectively utilized as single data port from the perspective of a user program.

According to the present invention, a cluster communications system is provided that supports reliable and efficient cluster communications. The preferred embodiment cluster communication systems can be used to provide this reliable and efficient cluster communication for cluster configurations extending beyond a single local area network (LAN). The cluster communications system provides reliable and efficient cluster communication by facilitating multicast messaging between systems in the cluster. In particular, the preferred embodiment provides for the establishment of multicast groups in between which multicast messaging is provided. The preferred embodiment provides this multicasting while providing the needed mechanisms to assure ordered message delivery between systems. The preferred embodiment extends this efficient and reliable cluster communication by providing for additional point-to-point communication between systems not on the same LAN. Thus, the preferred embodiment provides a cluster communication system that uses reliable multicasting for efficient cluster communication in a way that can be used for clusters that extend beyond a single local area network.

Method, apparatus and article of manufacture for acquiring a buffer after data from a remote sender (e.g., client) has been received by a local machine (e.g., server). Because the client data has already been received when the buffer is acquired, the buffer may be sized exactly to the size of the client data. In general, the buffer may be caller supplied or system supplied.

Method, apparatus and article of manufacture for continuous modes for both asynchronous accepts and asynchronous receives. A single asynchronous accept is performed on a listening socket and a single asynchronous receive is performed on each connected socket. The continuous mode inputs result in queuing data structures on a pending queue. The contents of the pending data structures on the pending queue are copied to completion queues, while the pending data structures remain on the pending queue.

Apparatus, methods and articles of manufacture for handling messages in a client-server environment. In general, computers of a client-server environment are configured with sockets to facilitate network communications. A socket of at least one of the computers is configured to recognize a format of a message to be received from another computer, whereby the socket is configured to handle receiving the message without invoking the application until the message is completely received. In general, the message may be formatted with a length field or terminating characters. In one embodiment, the socket utilizes a record definition to recognize the message format.
