Executive Summary

It is a very vital factor to allocate the resources for improving the QoS (Quality of service) for any network carrying various types of traffic. Real-time applications, such as video conferences, are in the most important to get the benefit of QoS adaptation. Several scheduling disciplines are employed at the router to guarantee the QoS of the network. Each scheduling discipline has its pros and cons. DiffServ (Differentiated Services) is an IP based QoS support framework that differentiates between different classes of traffic. The function of the core router of the network is to forward packets as per the per-hop behavior associated with the DSCP (Differentiated services code point) value.
