Internet Governance Glossary
Measure of overall network performance that reflects the quality and reliability of a connection commonly seen as the guaranteed minimum level of performance by the users of the network.
In packet-switched networks like the Internet with its abounding multimedia content and delay-sensitive applications, QoS is affected by various ‘human’ or ‘technical’ factors, resulting among others in the following problems as seen from the point of view of the sender and receiver:
- Low throughput,
- Dropped packets,
- Out-of-order delivery.
