Video is more than one-quarter of all
consumer IP traffic
Non p2p Internet video will account
for 50 percent of all consumer IP traffic
in 2012.
Non-Internet IP video will increase more
rapidly than consumer Internet

Youtube and other statistics
Youtube BW cost $1M per day (March 2008): Almost $0 today
Youtube traffic is 10% of internet traffic
> 6B videos in January 2009 vs. 2B per day in June 2010
BBC iplayer 7-10% of UK internet traffic
P2P from 60/70% to 35% but triple from 2006
IP Video 35% of internet traffic in 2009

What if Traffic Patterns change?
Network Architecture is optimal today, but will it be optimal in 2 years?
Traffic patterns’ evolution is uncertain.
What if the access technology changes?
Huge volumes of traffic can move
What if the local University blocks peer-to-peer?
What if Google/YT or likes enter/leave the country?
What if multiple peering points are introduced internationally/locally

Carrier Class
© 2007 Cisco Systems, Inc. All rights reserved. Cisco Confidential 15
Four Primary Causes for Packet Loss
Excess Delay
Packets delayed beyond an acceptable bound are effectively lost
Can be prevented with appropriate QoS (i.e., Diffserv)
Congestion
Considered a catastrophic case, i.e., a fundamental failure of service
Must be prevented with appropriate QoS and admission control
PHY-Layer Errors (in the Core)
Can apply in both core and access – although occurrence in core generally insignificant compared to losses due to network failures
Network Reconvergence Events
Network level approaches can be used to reduce any loss experienced
Application or transport level approaches can be used to recover from loss experienced

Traffic Type and Linecard Profiles
Initial assumptions are that core/uplink were the most alike and edge needs to be a separate card
Wholesale Edge/Peering feature set does not need the same level of scale as retail edge and may fit better with core/peering
