EVENT QUEUE MANAGING SYSTEM

摘要

In a computer system 1, an operating system 5 in a kernel 4 has a common event queue 6 in memory shared with a network interface controller NIC 3. The NIC 3 receives events such as data packets from a network 2 for delivery to applications 7¿1?, 7¿N? which are run one at a time on the computer 1. Each application has its own event queue 8¿1?, 8¿N? and, when this becomes empty, the currently running application requests delivery of events 30. The operating system 5 distributes 33-36 events from the common event queue 6 to all of the applications 7¿1?, 7¿N? for which events in the common queue 6 are destined.
