Abstract
Disclosed herein are a communication control method and a network system. When a total band of a priority flow and a best-effort flow in any one of switches SWand SWand hosts Hto Hconnected to a network exceeds a predetermined value, priority control is executed to make the priority flow take precedence of the best-effort flow and flow control is executed to limit the band of the best-effort flow. Thus, priority data such as sounds and moving pictures can be transmitted in a high-quality and reliable transmission without turbulence. As a result, it is possible to provide a communication control method and a network system offering high-quality communications even if transmitted data includes sounds and/or moving pictures.
