ARQ PROTOCOL SUPPORT IN VARIABLE SIZE DATA TRANSMISSION ENVIRONMENT USING SEQUENCE NUMBER APPROACH OF HIERARCHICAL STRUCTURE |
摘要 |
PROBLEM TO BE SOLVED: To optimize the protocol balance and to secure the sequence numbering to optimize a PDU(protocol data unit) by transmitting a variable size PDU by means of a hierarchical sequence numbering space approach technique that can support an ARQ protocol in a variable transmission rate environment. SOLUTION: An HSNS(hierarchical sequence numbering space) approach necessary for management of a sequence number space can be managed in a very easy way and also can use a simple tree data structure since a buffer contained in a transmitter or receiver is managed to the retransmission. That is, if a very large PDU is transmitted in an environment of a high BER(bit error rate), an additional function is supplied in a communication environment. A highly reliable transmission protocol cab use three schemes to fractionize a PDU into small logical transmission units.
