Part 3: New Answers for Bringing Scale to the Carrier Ethernet Metro Edge

Sep 23, 2013 by Brian Van Voorhis

Overture's Product Manager, Brian Van VoorhisService providers want to scale up service capacity and accelerate service delivery as they transition their edge network away from a legacy non-MEF compliant Metro Edge.  In the first part of this article series (Problems? What Problems?) we looked at the intrinsic problems in a legacy, non-MEF Metro Edge that providers are trying to solve.  In the second part (Options to Scaling the Metro Edge) we discussed the cost and complexity tradeoffs associated with extending MPLS from the core to the edge of the network. 

So is there another option?

Yes. New CE2.0 switching and aggregation solutions, like the Overture 6500, coupled with software control and orchestration solutions, like Overture’s Ensemble OSA™

How do you define an optimized architecture vision that enables service providers to scale up their service capacity and speed of delivery and migrate from a non-MEF edge/aggregation network to a MEF-compliant network? 

In Part 1 of this series, Problem?  What Problems? we looked at the challenges facing service providers at the network’s metro edge.  In this article we consider options for a potential solution, focusing on the merits of extending MPLS from the core to the edge versus building CE 2.0 on-ramps from the edge to the core.  In the third segment series we will explore an optimized solution that addresses the problems.

Brian Van Voorhis of OvertureMany service providers are searching for new ways to scale up their service capacity and speed service delivery as they transition their edge and aggregation network from a legacy non-MEF network to one that is Carrier Ethernet CE 2.0 compliant. In this blog series we outline an optimized architecture vision that helps service providers migrate from a non-MEF edge/aggregation network to a MEF-compliant network.   The factors we consider are a) the embedded base of bridging elements in the edge /aggregation network b) the establishment of MPLS in the core and c) how software defined networking (SDN) and network functions virtualization (NFV) concepts potentially alter the landscape in planning a solution.

Even as total capex budgets remain flat today, service providers continue to grow their Carrier Ethernet investment and make it a larger portion of their budget each year.
