PTC 2014 Presentation The dynamic Asia-Pacific region needs a single, integrated subsea-terrestrial network powered by OTN switching, GMPLS, and intelligent protection. This architecture provides the flexibility and agility necessary to provide services and operational speed that will be the “New Normal” for service providers.

Why Unified Network Architecture?
Globalization of traffic
Cloud. Big Data. Big Science.
High bandwidth flows. Ultra Long Distances
Growing complexity
DWDM. OXC. Routers
Metro. LH. Submarine
Cost of Disruptions
Reliance on Fiber Infrastructure
Significance of Survivability
