Dear Sirs,

excuse me please for bothering you with the following information, but I 
thought it could be of use for you as well.

Increasing Internet traffic and the transfer of delay and loss critical 
traffic may lead to congested interconnection links and dropping of the 
"wrong" packets as a result.
This is particularly regrettable, if the interconnected partners both use 
traffic differentiation in their networks and are cut back to best effort 
interconnection (p2p or through IXPs).

I have proposed a concept for simple Inter-AS Class of Service 
interconnection that allows for consistent traffic separation even across 
interconnection points.

By means of this email, I would like to receive your feedback, whether the 
described situation is currently seen or expected in the next months.
Furthermore, I would be interested to hear, whether there have already 
been set up class of service based interconnections, which could make us 
of such an automated CoS signalling concept.

Background information about the proposed and implemented concept can be 
found at:

and

Thank you in advance,
Thomas Knoll
