I am looking for statistics about packet loss in the internet, with references to the sources of information.
1. What is average packet loss on Internet? (http://mpls-experts.com/blog/?p=18
says 4% but how do they know?)
2. I understand packet loss may occur because of a) excessive volume of traffic; b) bit errors or full link failure; c) bgp route convergence. How long does it takes for the routers to notice a problem and reroute the traffic?
3. If for whatever reason Internet route changes (planned maintenance) what kind of packet loss it incurrs?
Separate statistics globally/per region and for hosted severs/broadband subscribers will be greatly appreciated.
