Abstract

Basically Internet it’s a connection of small and large networks. From the beginning Internet used only for transferring some information between two computers but nowadays Internet are huge commercial communication network. As usual Internet used for communication between applications. The first Internet applications weren’t so sensitive for packets loss and delays. But in the modern Internet and networking applications requires more high level of connection quality, application become more sensitive for delays and packets loss and this is a reason to provide levels of quality (Quality of Service).The goal of experiment is studying applying QoS on network router (Access Router) to conform SLA (Service Layer Agreement). SLA includes End-To-End delay and Packet Delay Variation for Video Demonstration traffic. The approach to this paper is to use QoS functions to fulfill the specifications of the performance parameters in SLA between the operator and the customer. From the study it is found that using RSVP (Resource Reservation Protocol) gives better delay and delay variation results at the expense of more bandwidth.
