Bit errors and blocking
nReal-time
services for video and audio
nCan not tolerate
delays clearly observable by human (in order 200 ms or
larger)
nCan tolerate
relatively large error rates
nBlocking
probability depends on number of customers in a service area
nFixed rate
data services require much non-reusable capacity:
nFixed delay
ndemanding error
rate limit
nHigh-latency
data:
nLarge
flexibility in delay
ndemanding error
rate limit
