Title:
データ通信システム、データ通信装置、データ通信装置の制御方法、プログラム及び記録媒体
Document Type and Number:
Japanese Patent JP5451521
Kind Code:
B2
Abstract:
In a wireless communication network, a data communication device includes a wireless monitoring device, a path cost control device, and a communication path control device, thus functioning as a Layer 2 switch. 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. For example, a data communication path is switched to run through a LAN while blocking a wireless line. Hereafter, 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.
