CPSC 601.43 Topics in Multimedia Networking
The Twelfth IEEE International Workshop on Quality of Service IWQoS, 2004.
The capability to provide resource assurance and service differentiation in a network is often referred to as quality of service (QoS).
Edge RouterDifferentiated Service (Diff-serv)
Uses a combination of edge policing, provisioning, and traffic prioritization to achieve service differentiation.
of the network.
- User can choose to pay more for a QoS requirement to increase the likelihood of receiving the better service.
- where, ci= cost function for agent I
C= revenue goal
(1) Quality of Service: For an agent with optimal allocation
, an allocation b of bandwidth is defined to achieve a QoS value of Q( , b) = b/
(2) Probability of allocation: Fraction of agents who receive at least , their minimum acceptable allocation ( ).
(3) Fairness rank, F(i) is proportional to
