To reduce processing load or processing time required for compression and encryption of data. Data to be compressed, such as image data, is divided into specified block sizes by am image divider (). A quantizer () references a quantization table () to quantize each of these blocks of data. The result of this quantization is entropy encoded by an entropy encoder () referencing a coding table () to acquire compressed data. An encryptor () encrypts the quantization table () and coding table () used in the quantization and encoding using a specified encryption method. A multiplexor () gathers together the encrypted data acquired as a result together with the compressed data in a specified format.

Device for compression and encryption, and device for decompression and decryption

When a movement detector section detects that a network device has been moved, a deletion section causes the deletion of pre-movement positional information stored in a positional information storage section. When an alert output section detects a state in which no positional information is set in the positional information storage section, the alert output section outputs an alert. A positional information setter section updates the positional information storage section with post-movement positional information of the network device which is input by an administrator in response to the alert so that the actual installation position matches the positional information set in the positional information storage section. In this manner, the network device avoids a situation in which positional information indicating an installation position before movement is still set even after the device has been moved.

A data transmission control information acquisition section generates data transmission control information based on control information exchanged between applications of a data transmitter and a data receiver before data transmission is started. A data transfer control section determines a bandwidth to be used by the data transmission, transmission start time, etc. in a shared transmission medium in a unified manner based on the data transmission control information and current bandwidth use conditions, and transmits the thus-determined information to the data transmitter. The data transmitter transmits data to the data receiver via the transmission medium under unified management.

A data transfer apparatus and method uses recovery-type congestion control and avoidance-type congestion control. A bandwidth determination unit determines a requested bandwidth for a congestion avoidance-type data transfer in accordance with control information communicated between applications prior to the congestion avoidance-type data transfer. A bandwidth estimation unit estimates a bandwidth having been used by a congestion recovery-type data transfer in accordance with the control information communicated between applications prior to the congestion recovery-type data transfer. A management information memory stores information data of all the congestion avoidance-type data transfers and congestion recovery-type data transfers that use the bandwidth at a particular moment (i.e., simultaneously). A bandwidth allocation unit determines whether a newly requested congestion avoidance-type data transfer can be performed in accordance with an unused bandwidth and a bandwidth requested by the new data transfer, and allocates a certain amount of bandwidth to the new congestion avoidance-type data transfer. A data transfer instruction unit instructs an application to perform new data transfer.

Data transmission apparatus and method

A data transmission apparatus in which the bandwidth necessary for an application is determined and is communicated to a transmission interval counting function. The transmission interval counting function determines a transmission interval according to the necessary bandwidth and effects transmit control on a transmission unit transmitting function with timing set at this transmission interval so as to transfer data in a desired bandwidth. Owing to the above construction, even when a plurality of types of applications for transmitting data at desired times exist and they perform data transmissions while sharing the use of a network, the contention between the data transmissions in the network can be prevented from occurring. This prevents data losses and delays in data transmission from increasing.

The present invention provides a data transmission system having a data sending unit, a data receiving unit and a data transmission medium for data transmission from the data sending unit to the data receiving unit, which comprises an element for generating feature information of data transmission from the data sending unit to the data receiving unit in advance of execution of the data transmission, an element for storing change of states of use of a bandwidth by data transmission now under execution, an element for predicting a time of completion of the data transmission now under execution based on the change of states of use of the bandwidth and the feature information of the data transmission now under execution, an element for determining a transmission rate for data transmission to be next executed at the time of completion of the data transmission now under execution based on the change of states of use of the bandwidth and the feature information of the data transmission to be next executed, and an element for executing the data transmission to be next executed from the data sending unit according to the transmission rate at the time of completion of the data transmission now under execution.

Data transmission system having feature for predicting time completion

A contention control system unitarily manages a plurality of data transmissions so as to avoid contention therebetween. Data transmission command sending equipment of a data receiver continuously sends data transmission commands to a data sender according to a data transmission request. Data transmission-command receive control equipment receives the first valid one of the continuously-delivered data transmission commands therein and delivers it to data transmission control equipment. Correspondingly, data sending equipment starts to transmit data. Data transmission monitoring equipment of the data receiver monitors the state of transmission of the data. When the data transmission corresponding to the data transmission commands is made, the data transmission monitoring equipment detects it and notifies the result of detection to data transmission-command transmit control equipment, which in turns terminates the notification of the data transmission commands in response to its notification delivered from the data transmission monitoring equipment. Thus, a reduction in the efficiency of bandwidth utilization at the time that transmission errors are produced in the notification of the above commands can be restrained.
