Document Type and Number:
Japanese Patent JP2001512930
Kind Code:
A
Abstract:
The present invention provides a system and method for transmitting and receiving data that can transmit data over a plurality of data paths simultaneously and that provides a plurality of transmission queues which enable data transmissions to be continuously prioritized and which do not cause bottlenecking of data. In the preferred embodiments, the present invention comprises a data transmission facility, at least one forward data path, at least one data reception facility, and at least one reverse data path. Data is transmitted in response to a request to transmit data which may be locally generated at the data transmission facility, or may be remotely generated at any of the data reception facilities and transmitted to the data transmission facility through the reverse data path. The requested data is then transmitted from the data transmission facility through at least one forward data path to at least one data reception facility. Data is transmitted in the form of at least one header packet and at least one data packet for each data file. In the event that errors are detected in this transmission of data, retransmissions of the corrupted data may then be requested by any of the data reception facilities through the reverse data path. The transmitted data is finally received by at least one data reception facility, where a copy of the requested data file is recovered and the data is used as desired.
