Low-latency communications

摘要

A method of handling communications by a computer. A system-call communication routine receives a request of an application to perform a socket-related task on a given socket in a blocking mode. The routine repeatedly performs in alternation polling of one or more input/output (I/O) devices servicing the computer and performing the socket-related task.

1. A method of handling communications by a computer, comprising:
receiving by a system-call communication routine running on the computer, a request of an application to perform a socket-related task on a given socket in a blocking mode; selecting a timing scheme for polling of a plurality of devices, in which different devices are assigned a different polling rate, the polling rate assigned to a specific device being assigned according to one or more parameters of data expected to be received from the specific device or a chances that the specific device will fulfill the received request; and responsively to the request, repeatedly performing in alternation, by the communication routine, the following:
polling a plurality of input/output (I/O) devices, in accordance with the selected timing scheme, at least one of the I/O devices being polled more frequently than other polled devices; andperforming the socket-related task.
