摘要： A wireless network relay apparatus includes a Layer 2 switch 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.

摘要： In a wireless communication network, a data communication device (e.g. a Layer 2 switch) includes a wireless monitoring device, a path cost control device, and a communication path control device. Due to an increase of path costs in wireless areas, the path control device recalculates path costs over a network so as to carry out switching to an appropriate data communication path, e.g. a LAN with blocking a wireless line. When a wireless band is recovered due to an AMR function, the wireless monitoring device sends a path cost change request to the path cost control device, which in turn reduces a path cost at a wireless line port. Additionally, the communication path control device recalculates path costs over a network so as to switch over data communication paths. Thus, it is possible to select an optimum data communication path with a low cost.
