Studie - 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
