Abstract
A data optimization unit divides data of a TCP application into chunks. Then, the data optimization unit calculates a hash value with respect to the chunk, and searches a hash information storage unit from the hash value and a data size of the chunk, and thus, determines duplication of the chunk. Then, in a case where there is no duplication of the chunk, the data optimization unit stores the chunk, and stores the hash value, the data size of the chunk, and the position of the chunk in a hash information storage unit. Then, the data optimization unit compresses the chunk, and transmits compressed data to a transport optimization unit.
