20120020222 | PATH CONTROL DEVICE, PATH CONTROL SYSTEM, PATH CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM - Provided are a path control device and a path control method for maintaining a constant communication quality between wireless links in a network including a plurality of wireless links with varying transmission rates. A path control device | 01-26-2012 |
20120243415 | BANDWIDTH CONTROL DEVICE, BANDWIDTH CONTROL METHOD, AND WIRELESS NETWORK SYSTEM - In a network configured using a wireless link in which a transmission rate fluctuates, accommodation efficiency of traffic is improved while communication quality of VBR traffic is maintained. A bandwidth control device includes a stability level calculation unit which calculates a stability level indicating a probability that a bandwidth is available in a wireless link using adaptive modulation, a utilization rate calculation unit which calculates a utilization rate of a bandwidth used by traffic to be accommodated, an allocation unit which allocates, to the traffic, a link bandwidth of the stability level corresponding to the utilization rate of the traffic, and a path control unit which sets a path for the traffic in the wireless network including a communication device that performs communication over the wireless link based on the allocated link bandwidth. | 09-27-2012 |
20130083663 | PATH CONTROL DEVICE AND PATH CONTROL METHOD - A path control device according to the present invention is a path control device | 04-04-2013 |
20130329564 | COMMUNICATION PATH CONTROL DEVICE, COMMUNICATION DEVICE, COMMUNICATION PATH CONTROL METHOD, COMMUNICATION METHOD, AND PROGRAM - The problem of the present invention is, in a network configured from wireless links that can use an adaptive modulation function, when using 1+1 protection, to maintain communication without dropping of data occurring even if there is a drop in the transmission rate as a result of adaptive modulation. The invention of the present application having: an investigation means that, for every communication method that can be used in each of a normal pathway and a backup pathway, investigates an available band that is a band that can be allocated when the transmission rate of the normal pathway and the backup pathway has decreased; and a control means that, on the basis of the investigated available band and a band that a flow is requesting, sets marking in a manner so that the packets of the same flow in the normal pathway and the backup pathway can complement each other. | 12-12-2013 |
