Abstract
Provided is a server delay control device for a server in which an OS having a kernel is deployed. The OS includes: a ring buffer managed by the kernel; and a poll list in which information on a net device of a hardware interrupt from an NIC is registered. The server delay control device is deployed in the server and configured to receive a timer interrupt at predetermined specified intervals and monitors a packet arrival and includes: a packet arrival monitoring part configured to check the presence or absence of a packet in the poll list upon being triggered by the timer interrupt to monitor the poll list; and a packet dequeuer configured to, when a packet has arrived, reference the packet held in the ring buffer, and perform dequeuing to remove the corresponding queue entry from the ring buffer.
