Oliver,
1. Basically, you can implement any matrix as a list. You can even implemented it
as a one dimensional array.
Note: In our case, the matrix represents a graph.
2. The overhead with the matrix approach is very limited.
3. I'd rather have a structured general purpose solution as opposed to a restrictive one.
The objectives here are to provide a solution that works as opposed to limiting the
CDN peering concept due to the limitations of the DNS based method.
4. Do we know from content providers if the one or two levels compromise is ok or not???
PS: I am not promoting the matrix approach for any personal reasons, I just want a flexible
general purpose solution.
