Packet drop versus delay trade-off
Applications have a tolerable value of network delay (e.g. voice ~200ms)
Packets seeing more delay than the tolerable value will be dropped
Plot shows percentage of packets dropped versus tolerable end-to-end delay
- For delay of 200ms, about 5% drop rate
- If tolerable delay is 150ms, 15-20% drop rate!
- Performance of application is going to depend on the choice made for this trade-off
