I have just returned from my first scientific conference. It was PPAM 2007 held in Gdansk, Poland. The most important thing is that I went there not only as a “viewer”, but as an active participant, presenting my first paper — End to End QoS Measurements of TCP Connections. The article will be published in upcoming LNCS (Lecture Notes in Computer Science) by Springer. The article will also be published on my website after the print is complete. Here is the abstract:
This paper presents selected issues on quality measurements of TCP connections, seen from the end user’s perspective and not from the service provider’s point of view. The main focus is put on selection of parameters, which values are worth gathering, and can be gathered without disturbing end user applications. To verify the presented ideas, a measuring tool — QMP (QoS Measurement Plug In) was developed. QMP is placed inside the kernel of Linux 2.6 operating system as an extension to the packet ï¬lter. The paper shortly describes the tool and some experiments performed with it.
Nice. Did you write the tool yourself? What about the code?
Or is it closed source :)?
Regards
Yes, I have written it myself. It’s basically a simple Linux kernel module, so it wasn’t hard. The code… well… when the paper is published I will probably publish the code as well, but it’s not what I’d call mature, so I have to think if it’s worth publishing. It’s just a proof of concept that the method works.
