Abstract
A first network deviceand a second network devicetransmits a test frame and its response frame therebetween. The first network deviceacquires a test frame transmission start time, a response frame reception completion time, a test frame reception completion time, and a response frame transmission start time, and calculates, based on the times thus acquired, a PAUSE frame action delayed period that indicates a time period required for a PAUSE frame transmitted from the first network deviceto actually act on the second network device, and sends from the first network deviceto the second network devicea PAUSE frame in which a time period calculated based on the PAUSE frame action delayed period is set as a PAUSE period in order to prevent shortage of a receive bufferin the first network devicefrom causing a loss of frames transmitted from the second network device
