Server delay control device, server delay control method, and program

A server delay control method of a server delay control device for performing, on a server, packet transfer from an interface part of a computer comprising one or more hardware processors, the server comprising an OS and implemented using one or more of the one or more hardware processors, the OS comprising:

• a kernel in which the server delay control device is deployed;
• a ring buffer managed by the kernel, in a memory space in which the server deploys the OS;
• and a poll list in which information on a net device is registered, the information on the net device being indicative of which device a hardware interrupt from an interface part comes from, the server delay control device implemented using one or more of the one or more hardware processors and configured to receive a timer interrupt at predetermined specified intervals, the server delay control method comprising steps of:
• configuring, by the server delay control device, the timer interrupt as a hardware interrupt and checking, by the server delay control device, the presence or absence of a packet in the poll list upon being triggered by the timer interrupt to monitor the poll list;
• and
• when a packet has arrived, referencing, by the server delay control device, the packet held in the ring buffer, and performing, by the server delay control device, dequeuing to remove a corresponding queue entry from the ring buffer.

A non-transitory computer-readable medium storing a computer program for a server delay control device for performing, on a server, packet transfer from an interface part of a computer comprising one or more hardware processors, the server comprising an OS and implemented using one or more of the one or more hardware processors, the OS comprising:

• a kernel in which the server delay control device is deployed;
• a ring buffer managed by the kernel, in a memory space in which the server deploys the OS;
• and a poll list in which information on a net device is registered, the information on the net device being indicative of which device a hardware interrupt from an interface part comes from, the server delay control device implemented using one or more of the one or more hardware processors and configured to receive a timer interrupt at predetermined specified intervals, the computer program causing the server delay control device to execute steps comprising:
• configuring, by the server delay control device, the timer interrupt as a hardware interrupt and checking, by the server delay control device, the presence or absence of a packet in the poll list upon being triggered by the timer interrupt to monitor the poll list;
• and
• when a packet has arrived, referencing, by the server delay control device, the packet held in the ring buffer, and performing, by the server delay control device, dequeuing to remove a corresponding queue entry from the ring buffer.
