With development of digital home appliances, the necessity of technology that guarantees low delay among digital devices in the LAN is increased. The
study presents a transmitting isochronous packet method for time-sensitive traffic applications. The proposed method includes an information module, a scheduling module, and a forwarding module. The
information module receives and records the media information of the plurality of multimedia streams.
The scheduling module calculates the guaranteed bit rate of each multimedia stream according to the media information provided by the information module. The scheduling module also rearranges isochronous packets of the multimedia streams in the first time slots of a plurality of clock cycles according
to the guaranteed bit rates so that the transmission of the isochronous packets satisfies the guaranteed bit rates. The lengths of the first time slot and a clock
cycle are in a predetermined ratio. The forwarding module transmits all the packets of a clock cycle to a network at a time interval of the predetermined length.
The simulation result of the proposed method can reduce 67% of the time-sensitive transmission delay for a 100% load.
