Best effort service data network, with First In First Out (FIFO) queuing discipline could not give guarantee for stable quality of service, because all traffics are treated equally, thus the given service will be depend on the traffic load exist in the network at the moment. For real-time traffic with strict requirement of delay, jitter, and packet loss, the best effort service is not suitable anymore. Because of this reason, best effort service need to be replaced with other mechanism that gives better quality of service.<p> <br /> <br /> The purpose of this final project is to give Quality of Service (QoS) by implementing Differentiated Service (DiffServ) in a testbed network, to measure and analyze the service quality of a DiffServ based network, and to find best queuing discipline to handle Expedited Forwarding (EF) dan Assured Forwarding (AF) traffic classes.<p> <br /> <br /> The DiffServ was implemented in a testbed network using Priority Queuing (PQ) and Hierarchy Token Bucket (HTB) queuing discipline. The testbed network connected the Digital Signal Processing (DSP) lab in Labtek VIII building, Bandung Institute of Technology (ITB) and Pusat Antar Universitas (PAU) building, ITB. The testbed network was built using Linux based router.<p> <br /> <br /> Experiments performed show that DiffServ is able to classify incoming traffic into appropriate traffic classes and gives different service for each class. The results showed that an Expedited Forwarding (EF) traffic class with strict delay, jitter, and packet loss requirements is best handled when given first priority queue using PQ discipline, while an Assured Forwarding (AF) traffic class is best handled using HTB queuing discipline to give guarantee of network capacity for each class.
