THRESHOLD ON UNBLOCKING A PROCESSING NODE THAT IS BLOCKED DUE TO DATA PACKET PASSING
摘要
<p>A threshold mechanism is provided so that a producer and a corresponding consumer, executing on the same resource (e.g., CPU) are able to switch context between them in a manner that reduces the total number of such context switches. The threshold mechanism is associated with a buffer into which the producer stores packets up to a given threshold before the consumer is allowed to remove packets. The buffer has an associated upper limit on the number of packets that can be stored in the buffer. A flush empties the buffer of any remaining packets when no more packets are to be produced. This reduction in the total number of context switches in general leads to better performance at the cost of more latency.</p>
