IP traffic growing exponentially!

Traffic increasing (but not due to voice)

• IP traffic between US and Sweden greater than 10 times the total voice+FAX traffic

Fixed Links - arbitarily fast:

• LANs: 10Mbits/s, 100Mbits/s, ...
• Backbones: 45 Mbits/s or 34 Mbits/s fi 155 Mbit/s, 662 Mbit/s, and Gigabits/s
  Transoceanic fibers between continents ==> Gbit/s
• Major sites link to backbones: T1 (1.5 Mbits/sec) or E1 rate links (2 Mbits/sec)
  fi increasingly 34 Mbits/s or 45 Mbits/s - even 155 Mbit/s in some metropolitan areas
• Individual users links: 28.8 Kbits/s and ISDN (128Kbits/s)
  ==> xSDL (Mbits/s .. ~51 Mbits/s in the fast direction)

Points of Presence (PoPs) + CIX and GIX ==> GigaPoPs
