Quality of Service (QoS) Management
- Bandwidth - how much? - when? - to whom?
- Jitter (variation in delay)
Notes:
QoS management is about making sure the system meets the requirements of the users, customers
Particularly important for Mulitmedia systems which transfer video and sound
Bandwidth - diameter of an “pipe”
Talking on the telephone with long delays can be very off-putting
Variations of delay between voice and video streams can lead to incorrect lip synchronisation
These are example characteristics of QoS which must be managed
