STREAM CONTROLLING/TRANSMITTING DEVICE FOR TRANSMITTING VOICE DATA ON THE INTERNET, ENABLING USER TO RECEIVE VOICE OF THE OTHER PARTY WITHOUT DELAY IN INTERNET PHONE SYSTEM

摘要

Purpose: river control/transmitting device is arranged to the sound for allowing a user to receive other side at once in a kind of internet telephone system, a video conference system or a multimedia transmission service for transmitting voice data on the internet. Construction: an information authentication and allocation unit (180) verify SCTP (stream control transfer protocol) datagram and identify association base on verification result. One path management unit (120) monitors whether that the different transmitting addresses of a relevant other side reach. One binding unit (160) multiple received data and control peel off as a SCTP datagrams in an IP packets and transmission or debundles it. One flow control/reliable unit of transfer (150) tool flow control and it is crowded avoid, such as the TCP on a face-port buffers a transmitted message until if necessary relevant other side notifies about it and starts to transmit it again. One SCTP controller (110) controls an associated state. If necessary first-class cluster engine (140) determines an order of transmission of a user datagram relative to every stream and divides or assemble user datagram.
