AT&T's challenge is to deliver more bandwidth in more places while scaling rapidly, said John Donovan, Chief Technology Officer (CTO), AT&T, speaking at the Goldman Sachs Communacopia XVII Conference. There are two key drivers for AT&T's network: Mobility and Video.
As recently as three years ago, video was a negligible factor of overall traffic. Last month, video exceeded 40% of total traffic across the AT&T IP backbone.
The proliferation of devices access in the AT&T network has also been dramatic, said Donovan. After 100 yeas of operating networks, AT&T recently surpassed 1 billion devices on the network. Donovan expects it will take less than 10 years to add the next billion devices.
Traffic growth is also huge. Industry-wide, backbone traffic is up dramatically, with growth at 50% year over year.
The company is now handling 15 petabytes of traffic daily.
Donovan said AT&T is uniquely positioned for 3 reasons:
- 1. Scale and Scope
- 2. Access network includes both wired and wireless
- 3. Building an all-IP network
In conclusion, he sees promising times for the business both from a market and technology perspective.
