Abstract
The chapter discusses setting up an Internet operating system (IOS) to meet quality of service (QoS) requirements in a wireless local area network (WLAN) environment. QoS refers to the ability of a network to guarantee to meet application quality requirements for various services while transporting application traffic end-to-end. Achieving QoS is a fundamental requirement for any network that supports multiple services that have distinct quality requirements and traffic characteristics. For example, QoS helps manage time-sensitive voice and video application traffic to ensure that it receives higher priority, and less delay and packet loss than best effort data traffic. In practice, QoS commonly refers to a set of enforcement techniques that are used to cope with congestion and meet the service quality requirements of various applications in multiservice Internet Protocol (IP) networks. QoS provides enhanced and predictable network performance by managing and minimizing network congestion.
