Abstract
In one embodiment, a method comprising receiving plural packets; and adaptively adjusting a pushtimer timeout value, packet aggregation threshold, or a combination of both based on a change in filtered rate of the received plural packets.
Claims20
A system, comprising:
- a network interface controller configured to:
- receive plural packets;
- and
- adaptively adjust a pushtimer timeout value and packet aggregation threshold based on a change in filtered rate of the received plural packets.

A method, comprising:
- receiving plural packets;
- and
- adaptively adjusting a pushtimer timeout value, packet aggregation threshold, or a combination of both based on a change in filtered rate of the received plural packets.
A network interface controller, comprising:
- a first register comprising a configurable packet aggregation threshold that sets a limit on a maximum number of packets the network interface controller receives before generating an interrupt;
- a second register comprising a configurable moderation period that controls how often the network interface controller computes a rate filtering function and adjusts an interrupt rate;
- and
- hardware decision logic that adaptively adjusts a pushtimer timeout value, the packet aggregation threshold, or a combination of both based on a change in filtered rate of received plural packets.
