Abstract
Differentiated Services is the most advanced method for traffic management which provides QoS. QoS is
essential for today’s internet. QoS represents set of techniques necessary to manage throughput, packet
loss and delay. Traffic Conditioners or Policers are the most important components of differentiated
services. In this research, different Traffic Conditioners or Policers are compared on the basis of QoS
parameters (Performance metrics) which are throughput, packet loss and delay to provide QoS on internet.
Traffic classification and traffic conditioning are important functions of differentiated services also known
as admission control which are governed by service level agreement (SLA). Traffic classification and traffic
conditioning is done by traffic conditioners at edge routers. Goal of this research is to choose the best
Traffic Conditioner to apply from source to destination pair because only one traffic conditioner can be
applied from source to destination so that QoS can be guaranteed.
