Table 1

Delay and QoS requirements of smart grid applications [11].

Application	Delay requirements (ms)	Priority (0: max to 100: min)
Teleprotection (for 60 Hz, 50 Hz)	8, 10	2
Breaker reclosers	16	15
Phasor measurement unit data + status (class A) for other than protection	60	10
Distributed automation periodic measurement + status, events, control	100	26
Dynamic Line Rating	200	28
AMI Priority	300	70
Transformer protection and control applications	500	80
Fault recorders	1000	90
Demand response applications	1000	90
Best effort traffic	2000	100
