Abstract
A wireless network relay apparatus includes a Layerswitch and a line control device as well as wireless/wired line terminating devices performing band limitation associated with an AMR function. It measures traffic passing through each line terminating device in inflow/outflow path directions. Upon detecting a modulation scheme changed due to an AMR function in a wireless area, it may specify a line terminating device so as to read a desired modulation scheme from a transmission source modulation scheme conversion table of the line control device based on traffic. It may change a local modulation scheme with a desired modulation scheme when a difference therebetween is above a predetermined number of stages. By tracking a modulation scheme changed for a transmission destination, it is possible to appropriately change a modulation scheme for a transmission source, thus suppressing traffic without discarding necessary data.
