Metro Edge

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™

Thinking Differently

Apr 22, 2013 by Prayson Pate

I recently started watching the “Downton Abbey” series, which takes place in the second decade of the twentieth century.  The characters are facing massive changes in their lives due to the rapid evolution of technology, including the growing presence of cars, phones and electricity.  Very quickly the characters will go from viewing these inventions as alien intrusions to being necessary parts of the infrastructure of daily life.  They will change how they think.

In previous blog entries I have covered some of the aspects of applying the cloud to the problem of telecom services.  In this segment I close the loop and talk about how we can apply the concepts previously discussed.  As with the characters in Downton Abbey, making this transition will require us to change how we think.

The Value of Open

In previous blog entries I discussed the value of cloud principles and tools.  A critical aspect of cloud development is the use of applications developed using open interfaces and standard protocols.

Services, Services, Services

Apr 8, 2013 by Prayson Pate

In previous blog entries I have talked about applying cloud and NFV (Network Function Virtualization) principles to the edge of the network.  In this entry I will talk about why these principles are important and how they can benefit the service provider.  These benefits fall into three categories related to services:

  • Service creation – The process of defining, implementing, and marketing new services
  • Service activation – The enabling of a service instance when ordered by a customer
  • Service assurance – The measurement and reporting of compliance with the Service Level Agreement (SLA).

Network Function Virtualization (NFV) for Access

Mar 25, 2013 by Prayson Pate

Network Function Virtualization (NFV) is an initiative being driven by an international group of large service providers to lower costs and simplify their networks.  The NFV white paper goes on to enumerate a number of candidate applications that currently reside in the edge but most of the focus has been on applications nearer the core of the network.  How can these principles be applied tot he metro edge?

Virtualizing the Edge

Mar 18, 2013 by Prayson Pate

In a previous blog entry I discussed some of the technology enablers that led to the success of the cloud, and how they could be applied to other domains such as the metro edge portion of the network.  One key enabler is the use of virtualization and Virtual Machines (VMs) to build the infrastructure of the cloud, which leads to the question, “Can virtualization be applied to the metro edge of the network?” Before digging in further, let’s step back and understand some of the key points of virtualization: abstraction and separation/layering.

The Cloud is a Mindset, Not a Destination

Mar 11, 2013 by Prayson Pate

People talk about the cloud as if it were a specific destination or set of destinations (“My music is in the cloud.”).  In fact, the answer to the question “Where is the cloud?” is “everywhere”.  The cloud is no longer limited to virtualized storage and services in a datacenter.  It is now a metaphor and model for distributed applications built on low cost hardware using Virtual Machines (VMs).
