Unprecedented growth (in a very short time) in global Internet traffic
- Most networks see 30-45% growth over a year
- We have seen 20-40% peak increase (usually in evenings) in
impacted regions, over the last four weeks (and in a few days)
- So far - networks appear to be meeting demand, but they were designed
to grow that much in a year (not in days)
- Content Delivery Networks (CDN) edge and peering links seem to have
enough headroom
- Stress is mostly on the aggregation networks and service edge routers
where demand may be reaching capacity maximums
• Big questions are what are the new ‘day-to-day and ‘weekend-toweekend’
slopes?
• Busy hour capacity was designed to address Sunday 9 pm online
streaming, but even weekend OTT streaming peaks are now
significantly higher
• We are also seeing unprecedented growth in latency-sensitive
applications during business hours:
- 300% growth in teleconferencing apps in the US (e.g., Zoom, Skype)
- 400% growth in gaming
