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.”
After, chatting with other cohorts in the industry (namely Greg Ferro aka Ethereal Mind and of PacketPushers fame, Stephen Foskett of Tech Field Day fame and also writer of his own blog, and Ivan Pepelnjak who, amongst other things, writes an excellent blog on networking topics), its clear that trying to stay up to speed with all the various happenings in going on in the data center is pretty near impossible because of the sheer volume of information and the signal-to-noise radio that sometimes gets out of hand. While all of us, in our own little ways are doing our piece to help address this through blogging, white papers, seminars and the like, we wanted to try something a little different to really dig into some of the more complex topics and came up with the concept of Virtual Symposiums:
Focused discussion on a single topic
Panel discussion with industry experts (or at least folks that believe themselves to be experts)
Focus on helping attendees understand the “how” and “why” of different technologies as opposed to advocating a particular perspective
Interactive, open to audience interaction--the goal is to get your questions answered
Our first symposium, next Tuesday, is going to cover storage convergence. Joining our panel for this discussion, we are lucky to have J Metz (@drjmetz) joining us to lend his FCoE and storage expertise. We will also get joined by special guest Stu Miniman (@stu), Principal Analyst from Wikibon who also brings perspectives shaped by over a decade in the storage market. We are going to spend approxiamtely the first half of the symposium discussing the storage options out their: FC, FCoE, and iSCSI and when we think each one makes sense (or not). As I noted above, the goal is to not push a particular technology agenda, but to educate you, and let you make your own decisions. The balance of the session is open for Q&A--we will cove some of the common questions that we see all the time, but we expect you, the audience, to drive a lot of the discussion.
So, mark you calendar and join us--if you are familiar with this crew, you know it will be both educational and entertaining.
What do you think of when you hear the word “innovation”? For me, it conjures up images of space flight, the wonder of the first distance communication, and the dizzying array of ways we’ve learned to use the network in the past 10 years. We’ve seen so much change, it’s sometimes hard to imagine what could come next. That’s why I’m excited that Cisco is delivering EG Everywhere—virtual access to the EG Conference series, which has been called “the premier gathering of innovators in art and science, media and technology, entertainment and education.” The bottom line: three days of unadulterated innovation and inspiration from April 12-14. Talk about finding new ways to recharge and reset.
To hear about the power of EG, click on the video below and listen to Cisco Senior Vice President Carlos Dominguez describe how last year’s EG conference impacted him.
CIOs around the world are at the center of technology trends such as cloud, social media, consumerization of IT, and mobility. This is the third blog in a four-part series (Read Part I)(Read Part II) exploring and sharing how CIOs around the world are responding to these trends and creating new ways to innovate, grow, and deliver superior customer experience.
Back in 2006, Gartner Research predicted that no company would be able to build or sustain a competitive advantage over the next few years unless it capitalized on the combined power of individualized workers and social dynamics. The “Future Worker of 2015,” Gartner said, would collaborate more, work alone less in order to be successful. Read More »
