Have You Checked Out Elastic Access at Cisco Live San Francisco Yet?

May 21, 2014 at 8:49 am PST

Written By Ram Haridasa, Senior Marketing Manager, Ciscoramharidasa

We talked about Elastic Access last week – how we’ve introduced new Carrier Ethernet innovations that will extend Cisco’s Evolved Programmable Network capabilities to the access with specific focus on automating the provisioning process and reducing operational costs for our carrier customers.

It’s one thing to read about it – quite another to see it. Join us this week at Cisco Live San Francisco and you can see Read More »

Cisco Introduces Elastic Access

May 12, 2014 at 7:50 am PST

With operational costs rising at a rate of 13% a year, carriers need to simplify their networks while leveraging virtualization and automation technologies to reduce the costs involved in bringing on new customers. What’s more, as bandwidth demands increase for video, mobile, and cloud services, network access can’t be a bottleneck for the customer experience.

At Cisco, we’ve now announced new Carrier Ethernet innovations that will extend Cisco’s Evolved Programmable Network capabilities to the access with specific focus on automating the provisioning process and reducing operational costs for our carrier customers.

First of all, with virtualization technology we’re bringing elasticity to access networks.  By leveraging Read More »

GPON in the Campus Network – A Misuse of Perfectly Good Technology?

March 21, 2012 at 1:11 pm PST

What’s wrong with running my campus network on Gigabit Passive Optical Network (GPON) technology you ask?

Let me count the ways!

I was just reading a White Paper by Nick Lippis of the Lippis Report entitled, “GPON vs Gigabit Ethernet in Campus Networking” that lays out the issues pretty well in my opinion, and concludes up front that GPON is “suited to niche applications” and that “many GPON assertions and claims are overstated.”

Nick does a nice job of contrasting the two approaches, a last mile SP technology (GPON) that might be a good choice for the home & kids, with a Highly Available Ethernet Design that should be used to run a real business.

I’ll leave it to you to read the details, but he covers facts on all the key areas from power consumption and cabling costs to network scaling, single points of failure, and troubleshooting capabilites.

All this adds up to GPON being a poor choice in the Campus when you look at the Total Cost of Ownership (TCO) even though the initial acquisition costs might be lower for the hardware itself.  When you look under the covers, the real price is quite high for GPON in terms of a “lack of flexibility, greater power consumption (certainly not green), limited network capacity, upgrades are system-wide events, troubleshooting tools and skilled technicians are limited and lacking, and multiple single points of failure exist.”

He goes on to say, with the Ethernet market being tens of billions of dollars, research and development is assured while competition privdes the motivation for innovation and feature enhancement.  An Ethernet campus network is a safe investment.

Caveat emptor!
