METHOD AND SYSTEM FOR P2P DATA TRANSMISSION BASED ON UDP

摘要

PURPOSE: A P2P(Peer to Peer) data Transmission method based on a user datagram protocol and system thereof are provided to assure a transmission sequence and transmission results by defining P2P communication protocols based on an UDP(User Datagram Protocol). CONSTITUTION: A transmission peer(100) divides data as a packet unit. The transmission peer respectively creates plural packets including total code numbers, transaction codes, and division codes. The transmission peer transmits packets to a reception peer(200). The reception peer transmits response messages including the total code numbers, transaction codes, and division codes of the received packets to the transmission peer.
