Quality of service, Computer Networking

Networks are more frequently being prepared to allow specification of the quality of service needed by users.

For example: - a typical voice telephone call may give a QoS parameter for throughput of 64kbps and time delay less than 500msec. A user transmit video might need throughput of 2Mbps.


There are three kinds of QoS specifications, which are shown as follows:


It is defined for video and audio, since these have predefined maximum speed.


It is defined for compressed video and audio where the data rate relays on the level of compression that may be achieved.


It is used for typical data functions and allows need of whatever bandwidth is available at a required time.
