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!

Video and Telepresence Integral to Supporting a Mobile Workforce

March 19, 2012 at 3:00 pm PST

Whether you work for a government agency, a hospital, or a school (or you attend school as a student) the verdict is in--you needn’t spend all day in your office, classroom, or examination room to productively do your job or complete your assignments.

Consider these examples: In San Antonio, Texas, detectives obtain search warrants via in-vehicle laptop telepresence connections to judges; doctors in a California hospital use tablets to videoconference with their colleagues; and, thanks to a telepresence-equipped mobile robot, Lyndon Baty, a 16-year old with kidney disease who cannot attend regular high school, interacts from home with his teachers and peers and participates in lessons as if he were sitting in the classroom.

In-Orbit Upgrades Enhance Security, Introduce IPv6 Support for IRIS

Cisco’s Internet Routing In Space (IRIS), the first solution to bring the networking capabilities of Cisco IOS Software to space, is continuing to transform the satellite communication industry.

The testing and deployment of IRIS has been full of industry firsts. In the most recent milestone, TeleCommunication Systems (TCS), Cisco’s partner in deploying IRIS services, this week announced that it has completed production integration testing and roll-out of a software upgrade to OS-IRIS, adding enhanced encryption and additional IPv6 support to the platform.

According to Michael Bristol, general manager and senior vice president of government solutions for TCS, “Cisco IRIS technology is transforming how government agencies and commercial organizations use IP-based network services to accomplish their objectives. This is another milestone in the long-term satellite industry collaboration between TCS and Cisco, and we look forward to increasing opportunities for both government and commercial markets to deploy more flexible and cost-efficient solutions.”

TCS OS-IRIS allows organizations to directly connect sites on multiple continents without the need for double satellite hops or the traditional connection to a commercial teleport. This converged solution enables voice, data and video traffic over a single IP network to increase efficiency and flexibility, compared with more fragmented, traditional satellite communication networks. Customers benefit from increased bandwidth availability, reduced latency, optimization tools and application flexibility delivered by TCS through an end-to-end Cisco secure IP network.

Telework Set to Go Mobile: One Year Into the Telework Enhancement Act

March 18, 2012 at 2:18 pm PST

The end of 2011 marked the one-year anniversary of the implementation of the Telework Enhancement Act of 2010. At the end of last year, Cisco partnered with the Telework Exchange to help convene a panel of telework experts, including federal agency leaders who have pioneered telework programs in their divisions, to hear the outcomes of these initial efforts and share insights into what the future of telework holds.

Reports from participating sections of the Library of Congress and the Treasury Department revealed workers experienced increased flexibility and job satisfaction as a result of having more opportunities to telework. The Treasury Department in particular saw higher productivity, improved emergency preparedness, and cost savings from reduced office space needs. Technology like telepresence has kept workers in disparate locations connected and allowed business to maintain—even enhance—its fluidity and efficiency.
