The Bring Your Own Device (BYOD) movement is taking hold in workplaces around the world, but some of my recent reading has led me to explore more deeply the impact of this trend on communication and security in the public sector.
An article in Forbes summed it up well: people rely more and more on smaller, mobile gadgets, and they’re using these devices to support telepresence and other collaboration tools to conduct work-related business. Though this embrace of BYOD (also called consumerization) means more flexibility to work from anywhere, more accessibility to coworkers and supervisors, and more opportunities for collaboration, it raises security concerns.
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.”
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.
