Abstract:
Today’s Internet only provides Best
Effort Service. Traffic is processed as quickly as
possible, but there is no guarantee of timelines or
actual delivery. With the rapid transformation of
the Internet into a commercial infrastructure,
demands for service quality have rapidly
developed. People of the modern world are very
much dependent on various network services like
VOIP, Videoconferencing and File Transfer.
Different types of Traffic Management systems
are used in those services. Queuing is one of the
very vital mechanisms in traffic management
system. Each router in the network must
implement some queuing discipline that governs
how packets are buffered while waiting to be
transmitted. This paper gives a comparative
analysis of three queuing systems FIFO, PQ and
WFQ. The study has been carried out on some
issues like: Traffic dropped Traffic Received and
packet end to end delay and the simulation results
shows that WFQ technique has a superior quality
than the other techniques.
