A Study Methods to Improve NAPI Polling Mechanism
GU Ruichun · Microcomputer applications · 2007
NAPI was proposed because a large number of network data packets to trigger a interrupt livelock.Although NAPI interrupted polling effective solution NIC to Kernel data packet reception,But a large number of data packets has not been timely processing,thus taking a lot of memory space.This paper presents a adaptive Polling daemonmethodology to improve NAPI.Test results showed that An adaptive Polling daemon can effectively improve the efficiency of packet capture data,reduce the memory occupied by the timely processing of packet data enable.
