摘要
Each deadline generator constituted by two counters is connected to each virtual channel, and based on the amplifier T flag signal EF from the independent FIFO queue and the virtual channel information sel_VC selected from the deadline comparator, (RT) for a head-of-line (HOL) cell of the asynchronous transfer mode communication network, the deadline comparator outputs a connection identifier (CID) for selecting a cell to be served based on the deadline The present invention relates to a real-time cue service apparatus using a virtual time algorithm using virtual time algorithms, in which data is input from a plurality of virtual channels (VC1 to VCn), and first to nth FIFO queues (10-n); (HOL) on the basis of the amplifier flag flags EF1 to EFn from the first to n-th FIFO queues 10 to n and the virtual channel information sel_VC selected by the deadline comparing means 40 First to n th dead time generating means (30 to n) for outputting dead time (RT1 to RTn) Compares the deadlines (RT1 to RTn) from the first to nth deadline generating means (30 to n) and outputs a virtual channel information (sel_VC) for connection of virtual channels having a minimum deadline Means (40); A multiplexer 20 for connecting a predetermined FIFO queue to be served among the first to the n-th FIFO queues 10 to n by using the virtual channel information sel_VC from the deadline comparing means 40,
