RE: YouTube outage underscores big Internet problem

We place a lot of inter-personal trust in the way the Internet is managed. Most BGP router owners are judicious about their work but this shows the flaws in the process. Are we supposed to inspect every packet, every router table?

RE: 'Radical rethinking' of Internet routing under way

Maybe the BGP implemntations should be re-written to be more effective. BGP in Cisco must have parts that are quite old and can be done more effectively today. Just take a look at OpenBGPD which is an example that a BGP implementation can save more memory.

There are a tremendous number of amazingly intelligent, diligent, committed people striving to make the Internet better.

Because of these efforts, BGP best practices change faster than those of other routing protocols. If you aren’t paying attention, you can get left behind.
