I'm writing a small manual for our self-developed protocol.

To show the packet structure we like to include a table like it's shown on this Wikipedia page:

Is there any prebuilt library for this purpose or should it be implemented by myself?

You might have a look to the bytefield package. – Claudio Fiandrino Jan 26 '13 at 9:33

You can use the bytefield package, developed exactly with the purpose of drawing protocol packet structures.

An example taken from the manual:



\bitheader{0-31} \\
\begin{rightwordgroup}{RTP \\ Header}
\bitbox{2}{V=2} & \bitbox{1}{P} & \bitbox{1}{X}
& \bitbox{4}{CC} & \bitbox{1}{M} & \bitbox{7}{PT}
& \bitbox{16}{sequence number} \\
\end{rightwordgroup} \\
\bitbox{32}{synchronization source (SSRC) identifier} \\
\wordbox[tlr]{1}{contributing source (CSRC) identifiers} \\
\wordbox[blr]{1}{$\cdots$} \\
\begin{rightwordgroup}{RTP \\ Payload}
\wordbox[tlr]{3}{MPEG-4 Visual stream (byte aligned)} \\
& \bitbox{16}{\dots\emph{optional} RTP padding}


The result:
