METHOD AND SYSTEM FOR DELIVERY OF LARGE CAPACITY DATA

摘要

PROBLEM TO BE SOLVED: To surely and stably deliver data of a large capacity to lots of terminal equipments by delivering the data of the large capacity with division through the use of a basic delivery protocol for a plurality of number of times and resending the data as to the data whose delivery is failed. SOLUTION: An AP processing section 403S of a server 400S divides data in an AP buffer 402S into blocks upon the receipt of an external delivery request and informs a delivery start notice to a terminal equipment 400R. An AP processing section 403 of the server 400S gives data to a delivery processing section 406S in the unit of blocks. Thus, the delivery processing section 406S has a block buffer 405S and delivers given blocks to the terminal equipment 400R by using a basic delivery protocol. AP processing sections 403S/R of the server 400S and the terminal equipment 400R record the success of delivery of each block. After the series of delivery of the data with a large capacity, the recording is referenced and the server 400S delivers the block whose delivery is failed to the terminal equipment 400R.
