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


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


Network Level Resiliency

NSF Awareness

IP Event Dampening

Bi-Directional Forwarding Detection (BFD)

Fast Convergence

iSPF Optimization (OSPF, IS-IS)

BGP Convergence Optimization (PIC)

Multicast Subsecond Convergence

Fast Rerouting (IP and MPLS)

System Level Resiliency

Control/Data Plane Resiliency:

HSA, RPR, RPR+, Stateful NAT/IPSec/FW,

NSF /w SSO including MPLS

BGP Nonstop Routing

Control Plane Policing, GLBP, HSRP,

Warm Reload

Planned Outages: ISSU, Warm Upgrade

Link Resiliency:

Line Card Redundancy with Y-Cable

Link Bundeling (Etherchannel/POS-Channel)

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
