Stars aligning for IP and optical transport convergence, and wide-scale IPoDWDM
Reducing the expense of expanding and operating IP and optical networks has been challenging in IP network evolution because operators needed to accommodate multipurpose network architectures. However, this is set to change as rapid and accelerating IP network traffic growth is forcing network operators to rethink how to build IP networks. Achieving higher margins requires blending efficient transport of IP traffic with creative, new multimedia services, and there are new signs that the time is right to optimize optical transport for IP networks. Improved IP service capabilities, network capacity, and performance with a lower cost per bit are now in reach.
Executive summary
In a nutshell
Ovum view
Accelerate IP network evolution, not revolution
It is a matter of perspective
The migration path from a multipurpose to a multimedia architecture
Video is the architectural tipping point
The legacy of voice-to-data transition: too many boxes, connections, and management systems
IP routers and ROADMs
Cornerstones of the IP NGN roadmap, but where are core Ethernet switching and aggregation/grooming?
Next step – IP over DWDM or IP over OTN?
Switching versus transport network operations center
Bits, frames, packets, and capex – the road ahead
Vendor strategies
Hybrid router/optical vendor approach
Router-focused, vendor-based IP-optical solutions
Optical transport vendor-focused IP-optical solutions
A key phase of service providers’ strategic IP transformation is at hand
The consolidation of IP and optical will have implications for vendors
