• Pandemic Analysis- Methodology similar to NANOG / SIGCOMM 2010 “Internet Inter-domain Traffic”
- Partnership with more than 50 providers around globe
• Data- Real-time streaming telemetry from most CSP backbone and aggregation routers
- Includes significant portion large NA, EU, Asia CSP as well as global transit
- Traffic volumes, applications, geographies as well as capacity and security

Pandemic Impact on Global Internet
• Unprecedent growth in global Internet traffic- Most network see 30-45% growth over one year
- Now seeing 30-60% peak (usually evening) growth over last four weeks in impacted regions
- Networks met demand and maintained QoE through “peak Internet”
• Industry response- Acceleration of port turn-ups (especially AWS, Netflix, Google) adding multi Tbps capacity
- Significant migration to cloud (e.g. Zoom moving to AWS, Oracle)
- Netflix, YouTube and Zoom reduction in video streaming rates
- Open / settlement-free peering (e.g. Telefonica)

Data Normalized Across US, EU and LATAM ProvidersDaily and weekly traffic patterns changed dramatically
45% traffic increase
schools closure
‘normal’ weekday Day 1 Weekend 1’normal’
weekend
Networks experienced typical yearly growths (40-50%) in just a few weeks (or days!)
Lockdown measures had a significant impact on network traffic:
- Increase of daily traffic
- Longer ‘hold’ hours
- Earlier start of video streaming hours
- Rise of videoconferencing
- Tremendous increase in weekend peak traffic

Application usage changes after one week of lockdown
Big changes in application usage, but how do they affect the network?
Anatomy of a “jagged mountain” (curve outlining daily traffic peaks)

Disney+ launched in several European countries on March 24
While still in the early days after the launch, Disney+ created unique challenges:
Disney+ launch
All content is sourced from peering since there is no dedicated caching infrastructure within the service providers’ networks
Disney+ now represents 8%of total video traffic…
…but 18% of video peeringtraffic
Disney+ leverages 6 different CDNs to source content and has the potential to cause traffic shifts (as traffic is dynamically balanced amongst CDN providers)

…and over 700% in some networksVideoconferencing growing 300%-400% initially
• Dramatic growth in conferencing applications
• Zoom has experienced growth over 700% since February 1 (select networks in the US)
Cloud coming to the rescue:
• Significant uptake of Zoom traffic by additional CDN domains (Amazon)for multi-CDN delivery of Zoom services
