Table 4

Proposed haptic class with DSCP marking scheme in addition to DiffServ service classes and DSCP marking scheme in [28].

Service class	Traffic characteristics	Tolerance to			Protocol	DSCP
		Loss	Delay	Jitter
Haptic	Fixed packets, real-time, inelastic and constant rate flows	Very low	Very low	Extreme low	UDP	EF
Telephony	Fixed size small packets, inelastic and low-rate flows	Very low	Very low	Very low	UDP	EF
Multimedia streaming	Variable size packets, elastic with variable rate	Low-meduim	Meduim	Yes	UDP	AF31 Af32 AF33
Low-priority data	Nonreal time and elastic	High	High	Yes	N/A	BE
