  • At least one first descriptor of-write first piece in the first register (3700), it is the information that each piece an of chunk indicates whether to comprise the first grouping block that each first descriptor comprises, each position of described first descriptor corresponds to and receives block, and its significance bit is;

    1 corresponds to described first grouping block;

    -determine to divide into groups based on the content of described first register in first piece, and in the 5th register (3710), record the identifier of described first piece;

    -at middle at least one second descriptor writing last block of the second register (3701), each second descriptor each piece of comprising for a described chunk indicates whether it is the information of last grouping block, each position of described second descriptor corresponds to and receives block, and its significance bit is;

    1 corresponds to described last grouping block;

    -determine to divide into groups based on the content of described second register in last block, and in the 6th register (3711), be recorded in the identifier of the last block in the grouping that will be transmitted;

    -in the 3rd register (3702), write at least one the 3rd descriptor (3311 to 333N), each 3rd descriptor comprises the information representing the state of each piece belonged in described chunk, the state of each piece indicates whether to store described piece thus, each position of described 3rd descriptor corresponds to and receives block, and its significance bit is;

    1 corresponds to the grouping block stored;

    Determine and in the 4th register (3712) state at least partially of record (97,98,911) described group, the storage of the block of described state representation in the described part of described group or do not store situation;

    -according to the state be recorded in described 4th register, set (43) comprises the grouping of described group described piece.
