METHOD FOR TRANSFERRING DATA FRAME END-TO-END USING VIRTUAL SYNCHRONIZATION ON LOCAL AREA NETWORK AND NETWORK DEVICES APPLING THE SAME |
摘要 |
A method for transferring an end-to-end data frame using virtual synchronization on a local area network and a network constituting apparatus are provided to secure service quality in the local area network without changing an existing Ethernet switch. A method for transferring an end-to-end data frame using virtual synchronization on a local area network includes the steps of: loading a virtual synchronization frame shaper for transmitting a frame through virtual synchronization between end stations(300,301,302,303) at a frame transmitting layer structure provided at the end stations(300,301,302,303) of transmitting/receiving sides passing through a plurality of Ethernet switches(322,324,326,328) in the local area network; mutually exchanging slot counters counted through the virtual synchronization frame shaper between the end stations(300,301,302,303), and synchronizing the slot counters; allocating transmitting time slots by the synchronized slot counters for transmitting the data frame between the end stations; and transmitting the data frame based on the synchronized slot counters and the allocated transmitting time slots.
