Time Scales for CL Service

• Assumptions of low queuing delay and little or no loss are given over long time scales

  • that is, over time scales larger than a “burst time” (time required for a flow’s max size data burst to be transmitted at the flow’s requested transmit rate)
  • over small time scales, occasional congestion may occur (normal)
  • over large time scales, problems are indicative of a failure of the CL service
