I spent the last few minutes to think about the topic of the first post on "IDR issues". For sure, the best I could do is to use this opportunity to introduce myself and explain the basic idea behind this blog.
So, let's start with the latter: "IDR issues": what is this blog about? A brief look at wikipedia is not really helpful at this point: "Indonesian Rupiah" or "Inner Distribution Road" is not what I have really in mind with IDR. IDR stands for "Inter-Domain Routing", which - simply speaking - terms routing of global addresses in the Internet. Today, the Border Gateway Protocol (BGP) is used for that purposes.
Even if the Border Gateway Protocol works fine in principle, BGP in its current state seems not to be the answer to everything. For example, by applying common (Autonomous System-)internal BGP schemes like BGP Route Reflection and AS Confederations, routing may end up in sub-optimal or inconsistent states. Routing processes may behave non-deterministic or even non-convergent. Besides operational problems, also security problems are present: In principle, it is really easy to hijack IP address space or eavesdrop on someones global network traffic. Obviously, all these possibilities are highly unwanted and problematic. Discussing these - for many, many people highly important but yet unknown - aspects and potential problem solutions is what I want to do in this blog. So, this is another technical geek blog ;-).
After sketching the basic idea behind this blog, its a good idea to introduce myself. My name is Uli Bornhauser. I am a computer scientist at the University of Bonn, Germany, and researching in the area of the correctness and security of the Border Gateway Protocol. If you are interested in more details, you can have a look at my website.
Finally, I want to say a few words about the "comment policy". If you have any remarks or suggestions, I'm very happy to hear about them! For that purpose, you can use the "post a comment" function you usually find at the end of each post or directly send me an email. You find my email address on my website.
For the future, I plan to write new posts every few weeks. Looking forward to see you again...
