Peter, congratulations again. - Could anybody help me a bit with SONET/SDH technology: what is the present state of - say STM4c vs STM4 etc.- standardization. At Stuttgart we run some 20km dark fibre driven by FORE`s ATM/STM4c boards (NEC SX4 32 - Cray T3E 512) - would we buy e.g. NORTEL SDH equipment if this would be - say 100km - and what about public European SDH? How is vBNS going to upgrade to 622Mbit/s ? What does the the below "Cisco's Native IP over SDH/VC4" exactly say? Paul ---- p.s.: ... if not the telephone system itself- would Christian prepare an analysis saying "a 600Mio participants Internet of `appropriate` capacity with RSVP and IPng would allow for concurrent AUDIO (as Jon said) of phone quality for everybody ..." :-) ------------------------------------------- On Dec 2, 2:28pm, Peter Lothberg wrote:
Subject: Re: Very fast IP, no ATM...
p.s.: have you any measures of IP-level throughput over this link?
Almost 2 moths of operation, 4h downtime and we have been running upto 120Mbit/s user traffic.
(Traffic generated by traffic generators does not count, but it's possible to fill it up to theoretical max.)
It's just a releif to see this first link that have enough buffer memory to deal with the network burstiness and allow TCP to do it's job..

Was the worlds first transatlantic 155Mbit native IP service brought into operation by Sprint/USA and Tele2/Sweden.
The circiut wich is part of Sprintlink and ICMnet runs between the NY-Nap in Pennsauken, NJ, USA and Tele2 in Sweden and uses cisco packet-over-sonet/sdh technology. (Native IP over SDH/VC4) -- End of excerpt from Peter Lothberg
