1.1 Overview

1.1.1 Introduction to QoS

Quality of Service (QoS) is a concept concerning service demand and supply. It reflects
the ability to meet customer needs. Generally, QoS does not focus on grading services
precisely, but on improving services under certain conditions.
In an internet, QoS refers to the ability of the network to forward packets. The
evaluation on QoS of a network can be based on different aspects because the network
may provide various services. Generally, QoS refers to the ability to provide improved
service by solving the core issues such as delay, jitter, and packet loss ratio in the
packet forwarding process.
