[e2e] internet architecture in Europe

[Jon Crowcroft]

around 10 years back we did internet synchronised juggling
between london and Amsterdam over the mbone - this was accompanied b
various pieces of cod jazz folk and classical guitar by an obscure UCL
researcher called crowcroft...
i believe the jugglers included stuart clayman and atanu ghosh...

more recently, there was a n internet handshake between people in
immersive VR caves in london and the US....


the seminal music session in the internet early multicast days was a 3
way between east and west coast in USA (eve schooler and martha
steenstroup and a metronome)....

if you want to do rallentando (or any serious interaction of tempo
between real players - especially jazz and classical) then yo uare
probably hit by speed of light limit on RTT at around
50-100km..(sorry, but i've tried it way back when even with crips QoS
enabled audio on a 155Mbps dedicated ATM CBR VC with the old
fore/nemesys AVA/AVD hardware, and if it didnt work then, it aint
gonna work on IP:-)

of course, the sort of sound (I wont glorify it with the word "music")
you eget in the eurovision song contest could probably be played by
robots from Tau Ceti and Aldeberan without anyone in the judges
noticing (and i am happy to include the Nul Points english entry in
this category:-)
