  2. LIST OF MODULES • Sender • Time Queue • Weight Queue • Routers • Receiver

  3. MULTICHANNEL SCHEDULER MODEL M= No of flows of input Traffic pi= Packets at position I in DOQ. li= Length of packet at position i. di= Deadline of packet at position i. Lmax= The total length of the packets concatenated in a single frame. Di= delayed channel models.

  4. SUPERFRAME ROUTER1 PACKET CONCATENATION AND CHANNEL SELECTION ROUTER2 DEADLINE ORDERED QUEUE p5 p4 p3 p2 p1 ROUTER3 DEADLINE REACHED

  5. DFD MSG DISP File name IP address RTR1 WeightQ Msg Display DEST RTR2 TimeQ • WEIGHT • TIME RTR3 MSG DISP SEND

  6. Level 0 Time Q Sender Weight Q Level 1 Sender Time or Weights packets

  7. Level 2 Sender Packet Time or Weight Concatenated Packets Routers Destination

  8. UML DIAGRAM sender Create Packets Select Queue Queue Send Concatenate Packets

  9. Router Set bandwidth Read Packets Forward Packets Receiver Receive Packets Save

  10. SENDER MODULE

  11. START SELECT Q AND BROWSE MSG IS TIME Q SELECTED TRUE FALSE FORWARD PACKETS TO TIME Q FORWARD PACKETS TO WEIGHT Q STOP Fig : Sender DFD

  12. TIME QUEUE MODULE

  13. START A CONCATENATE PACKETS START TIMER RECEIVE PACKETS CHECK STATUS AND BANDWIDTH OF ROUTER FALSE IS WAIT TIME== TIMER FORWARD PACKETS TO ROUTER STOP TRUE A

  14. SDO Algorithm

  15. WEIGHT QUEUE MODULE

  16. START A CONCATENATE PACKETS RECEIVE PACKETS FALSE CHECK STATUS AND BANDWIDTH OF ROUTER UPDATE QUEUE SIZE FORWARD PACKETS TO ROUTER IS QUEUE SIZE== WEIGHT STOP TRUE A

  17. LDO Algorithm

  18. ROUTERS MODULE

  19. START SET BANDWIDTH AND STATUS UPDATE RECEIVE CONCATENATED MESSAGE FORWARD TO DESTINATION STOP

  20. RECIEVER MODULE

  21. START RECEIVE CONCATENATED MESSAGE DISPLAY THE CONCATENATED MESSAGE STOP
