\chapter[QoS]{Quality-of-Service}
|
||||
|
||||
\gls{qos} is used to guarantie a minimum of service level to select applications. Often this encompasses \gls{voip} applications and \gls{av} applications being allocated the highest priority. It\tsq{s} not uncommon to allocate \gls{nmt} to the high priority queue, too.
|
||||
|
||||
Different mechanisms of handling access to network ressorces is used.
|
||||
\begin{itemize}
|
||||
\item \itemhead{\gls{nac}}
|
||||
\begin{enumerate}
|
||||
\item Which applications has access to what level of network ressources.
|
||||
\end{enumerate}
|
||||
\item \itemhead{Traffic Control}
|
||||
\begin{enumerate}
|
||||
\item Scheduling of traffic,
|
||||
\item classifiying traffic,
|
||||
\item marking packets based upon priority,
|
||||
\item marking packets based upon shaping traffic.
|
||||
\end{enumerate}
|
||||
\end{itemize}
|
||||
|
||||
\section{Concepts}
|
||||
|
||||
\begin{enumerate}
|
||||
\item Bandwidth,
|
||||
\item latency,
|
||||
\item jitter,
|
||||
\item realiability.
|
||||
\end{enumerate}
|
||||
|
||||
\section[Congestion Mgmt]{Congestion Management}
|
||||
|
||||
There are different ways to do congestion management. Which is in it\tsq{s} essence sorting of packets when a link reaches full capacity usage in the outgoing direction.
|
||||
|
||||
\begin{enumerate}
|
||||
\item \gls{fifo}
|
||||
\item \gls{pq}
|
||||
\item \gls{cq}
|
||||
\item \gls{wfq}
|
||||
\begin{enumerate}
|
||||
\item Flow-based \gls{wfq},
|
||||
\item class-based \gls{wfq},
|
||||
\item distributed \gls{wfq}.
