Background
• Internet usage grew 189% from 2000-2005
• Video and IP Rich Media Drive Growth
Household Bandwidth Needs in 2010:1x HDTV + 1x SDTV +2x PVRs + 1x VoIP Phone + 1x HSD = Overwhelming Capacity Requirements.
Twenty such homes would generate more traffic than traveled the entire Internet backbone in 1995.
• Impact of Video and IP Rich Media on SP networks
Worldwide SPs are enhancing their service offering (VoIP,HSD, Video, VPNs, etc…).
High bandwidth flows reduce the number of active flows that can be supported per 10Gig link.
Next-generation core routers provide > 10G ( 40G ) bandwidth per slot.
2 options for addressing core bandwidth needs:
•Native 40G interfaces.
•Multiple parallel 10G links.
Both options are NOT equivalent when considering available bandwidth.
