A system and method for controlling network traffic flow in a multi-processor network is disclosed. The method employs a two-part algorithm to determine when it is appropriate for a client node to transmit data over a network to one or more server nodes. The first part of the algorithm calls for the client node to transmit data over the network after receiving an acknowledgement from one or more of the server nodes to which data transfer is outstanding. The second part of the algorithm provides for the client node transmitting data over the network after a predetermined time interval has elapsed since a data transmission. The time interval is based, in part, on the length of outstanding data packets and a statistical analysis of the number of nodes transmitting or receiving data packets. The transmission of data over the network is accomplished by a hybrid scheme, comprising a combination of PUSH and PULL transmission protocols.

System and method for controlling network traffic flow in a multi-processor network

A method of interconnecting a new node into a cluster of other nodes. The new node broadcasts a configuration (DP) packet describing itself to the other nodes of the cluster. The other nodes then respond by setting up communications information enabling the new node to directly communicate with a monitor process in the responding nodes and sending that information (DI packet) to the new node. The new node then sets up information enabling the responding nodes to communicate with a monitor process on the new node and sends that information (DC packet) to the responding nodes. The responding nodes then acknowledge the information (DA packet) and the new node is then interconnected with the responding nodes. The DP and DI packets are sent via a permissive interrupt mechanism, received by each processor unit making up a node and forwarded to the monitor process of the node.
