Preliminary
send until another packet is enqueued. For each missed transmit opportunity, a cell can be sent at the peak
interval, which is one. In the 15 timeslots after the first cell, five cells are sent for an SCR of 50 Mbps. The
burst size is three, which is less than MBS. The unfilled slots can be used by other connections.
Timeline Example of Scheduling
CSKED Initialization
Before packets are enqueued for transmission, in addition to initializing the above scheduling parameters in
the LCD, the following registers need to be set up.
