12/26/11 Internet Protocol (IP).was designed to provide best-effort service. • VoIP • FTP QOS: Quality of Service (QoS) implies the ability to differentiate traffic streams and to define a level of performance for those traffic streams across a network. When heavily utilized networks are carrying various types of traffic for different users, QoS is a mean of offering better service Introduction to QoS: ,[object Object],[object Object]

Assured Forwarding (AFny) PHB. Expedited Forwarding (EF) PHB.

12/26/11 We have performed testing on 3 basic levels: 1. Marking: Testing if packets were marked according to specified classification. 2. ToS: Testing if the classification according to ToS and monitoring packets flow were mapped to the required PHB 3. PHB’s Implementation: Monitoring different rates assigned to each class 4.5 Testing procedure
