I am looking for a tool to draw a sequence of packets sent for a sliding window protocol. There are many tools for drawing message sequence charts with horizontal lines, but I want to be able to draw the lines diagonally, like the the bottom part of this image:
Please suggest suitable tools. I am most likely only interested in free ones, but if you have a really good suggestion for a commercial you can include that as well.

Lucidchart. A sequence diagram can also be made with Lucidchart. Users can draw various visual illustrations, from simple to technical diagrams. And like GitMind, this sequence diagram tool can improve the creation process with its collaboration feature.

SequenceDiagram.org is an online tool / software for creating uml sequence diagrams. All processing of parsing and painting the diagram is done client side in the user's web browser. This not only makes it snappy to work with, but it also means that your data isn't transferred over the Internet by the tool like in many other sequence diagram tools.

Create your own sequence diagram using a professional sequence diagramming tool called StarUML. This program was developed specifically to create UML diagrams like sequence diagrams. It offers standardized UML shapes including arrows and labels.
mscgen can do this, using the arcgradient option. This snippet wil render the second part of your example exactly:
msc { arcgradient=20; client, server; client => server [label="SYN"]; server => client [label="SYN + ACK"]; client => server [label="ACK"]; } If you copy paste this snippet in the mscgen_js on line demo, you'll see.

I've been using websequencediagrams. Essentially a webapp version of mscgen with a few different fancy renderers.
Websequencediagrams also exposes their diagram rendering as a script API. Now I store my diagrams as HTML files, commit them to git, show nice diffs, etc. I.e.,
<html> <body> <div class="wsd" wsd_style="rose"><pre> App->set_state PAUSE <!-- your wsd diagram commands, etc... --> </pre></div> <script type="text/javascript" src="http://www.websequencediagrams.com/service.js"></script> </body> </html> If you love us?
