20140355988 | COMMUNICATION CONTROL DEVICES AND METHOD - There is provided a communication control device including a communication control processing portion that performs at least one type of communication control processing when a control signal that requests a response signal is received from a partner device, a transmission processing portion that transmits the response signal to the partner device after the processing that the communication control processing portion performs when the control signal is received from the partner device, a processing time measurement portion that measures time that is consumed by the processing by the communication control processing portion, and a processing content setting portion that, based on the measured processing time that has been measured by the processing time measurement portion and on a response processing time for the response to the control signal, sets content of processing that the communication control processing portion will be made to perform within the response processing time. | 12-04-2014 |
20120257894 | DYNAMIC COMMUNICATION BANDWIDTH ALLOCATION METHOD, COMPUTER-READABLE MEDIUM STORING DYNAMIC COMMUNICATION BANDWIDTH ALLOCATION PROGRAM, SEMICONDUCTOR CHIP, AND PON SYSTEM - The present invention provides a station-side terminal device including a control signals reading/generating section that receives a requested bandwidth which the subscriber-side terminal devices require for the communication, from each of the subscriber-side terminal devices, and an uplink band allocating section including a first calculation section that allocates a usable communication bandwidth to each of the subscriber-side terminal devices based on a ratio of a service level parameter predetermined for each of the subscriber-side terminal devices, and a second calculation section that obtains an updated usable communication bandwidth updated by subtracting a sum of the allocated bandwidths from the usable communication bandwidth, and obtains an updated requested bandwidth updated by subtracting the allocated bandwidth from the requested bandwidth, to allocate the updated usable communication bandwidth to each of the subscriber-side terminal devices based on a ratio of the updated requested bandwidth. | 10-11-2012 |
20110150482 | Transmission control system, subscriber-side communication device, and office-side communication device - Provided is a subscriber-side communication device including a subscriber-side processing unit that continuously performs signal processing regardless of computer restart and includes a transmission processing unit that performs a data transmission process according to transmission control information contained in a received signal from the office-side communication device. Also provided is an office-side communication device including an office-side processing unit that continuously performs signal processing regardless of computer restart, and a transmission control information computing unit that computes transmission control information for each subscriber-side communication device, the office-side processing unit including a transmission control information storing unit that stores transmission control information of each subscriber-side communication device computed by the transmission control information computing unit, and a transmission control processing unit that performs a transmission control process with each subscriber-side communication device by using the transmission control information of each subscriber-side communication device stored in the transmission control information storing unit. | 06-23-2011 |
20110076022 | Optical communications network, power supply controlling method, station-side equipment, subscriber-side equipment, and semiconductor chip - An optical communications network that is composed of one station-side equipment being connected to plural subscriber-side equipments. The station-side equipment refers to downstream data signals and prepares transmission plans, and generates downstream control signals that include the transmission plans, and converts downstream signals, that include the downstream data signals and the downstream control signals to which identifiers indicating the subscriber-side equipments that are addressees are assigned, into downstream optical signals, and sends the downstream optical signals out toward the subscriber-side equipments. The subscriber-side equipment converts downstream optical signals into downstream electric signals, and refers to identifiers and extracts downstream electric signals addressed to itself, and reads the transmission plans, and generates timer control signals including information of receiving start times and receiving stop times, and, on the basis of the timer control signals, opens and closes a path connecting a receiving section and an electricity supply section. | 03-31-2011 |
