摘要： In a multi-processor system with a high degree of inter processor communication, an operating system extension is described as a kernel function to poll a receive buffer. This is an opportunistic poll that continues to run in the user context after an application process has invoked the kernel with a blocking receive function. It is also running whenever no higher priority task is running. New data packets may be received for the present user application process while avoiding context switches, and for a different user process while avoiding interrupts. A hardware implemented delay timer and a buffer fill monitor generate interrupts when the system is not polling, thus guaranteeing a maximum latency and preventing buffer overflow, but these interrupts are largely avoided by polling when the system is handling a large amount of inter processor data traffic.

摘要： A protocol suite for inter-process communication in multi-process and multi-computer environments is described which supports one or more loosely flow-controlled connections to be established over a tightly flow-controlled connection. The tightly flow-controlled connections between processes provide a reliable underlying network between the members of a multiprocessing environment over which multi-computer applications can then efficiently communicate by setting up loosely flow-controlled connections.

摘要： In a networked multi computer environment, with redundant links, network interface cards (NICs) are commonly duplicated and teamed to provide a recovery mechanism when network components fail. Embodiments of the present inventions avoid teaming of pairs of NICs and provide a computing host with redundant network connections for the computing host through a switch that is transparent to the computing host. The computing host itself; that is, its hardware and software, is relieved of the duty of network access redundancy and returned to the simple, simplex networking operating mode. The switch replaces a potentially large number of NICs and the need for computing host network access redundancy management which leads to hardware and software cost reductions and increases the robustness and reliability of the system through redundant network access.
