Who Will Benefit from NFV and SDN?

Cross fertilization creates innovation. As technologies mature and are successfully applied in one domain, there is frequently potential for using those technologies favorably in other markets as well. However, native technologies in one market might be foreign technologies in a different market. Assimilation is a complex process and outcome is difficult to predict.

IP and Ethernet were initially developed for enterprise networks. As those technologies promised significant simplification with operator networks, the cross fertilization journey started. Today we can conclude that most of the expected savings and efficiency improvements have been achieved. However, some deviances need to be noted. Read the full post

The Gigabit Conundrum

So far, 2014 has given us the XXII Winter Olympics, FIFA World Cup (congrats to Germany!) and Gigabit Broadband. And while the excitement from the two major sporting events has already waned, the excitement over Gigabit Broadband is just getting started.

Over the past year, the number of proposed and live gigabit networks has accelerated. The question is whether these proposed networks are setting customer expectations too high – especially in markets where they are “investigating” the opportunity, but may never actually build.

Imagine you live in a city that is being considered for gigabit broadband and then is not selected. That is a significant let down – especially if you are unhappy with your current provider. But even if your town is selected – there is no guarantee that your particular community and/or street will get this service. And for those that do – the wait for actual service could be years.

4K Video Highlights the Need for On Going Network Improvements

Over the past six months, there’s been a lot of talk about building a new, faster, better stronger Internet. A chunk of the discussion is driven by the proliferation of 4K video, the next new Big Thing being pushed by the broadcast industry since 3D video up and died. I think we all need to take a deep breath and get a reality check on the headaches that exist trying to tweak the status quo.

The current Internet core is fiber-based with some links ranging as high as 100 Gbps with more typical speeds in the 10 Gbps to 40 Gbps range. Moving out of the core into the edge is a mishmash of copper, coax cable and fiber connectivity, with speeds from sub megabit to gigabit or faster, depending on the technology available. Add in mobile connectivity and climbing wireless speeds in the megabit to tens of megabits, with promises of speeds up to near gigabit wireless. Read the full post

Big Data, Big Privacy Issues

In the world of Big Data – privacy and security have two very distinct meanings and functions, but they are inter-related. Security is related to the enforcement of policies related to computer use and electronic communications. These would include identity and authentication; authorization; availability; confidentiality; integrity and auditability. A failure in security becomes a threat to privacy, but violations of privacy can exist without a failure in security.

The promise of Big Data collection and its analysis is that the derived data can be used for purposes that benefit individuals, the economy, national security, medical research and urban planning – to name only a few. However, it is the amount of data being collected as well as the unexpected uses of data that are causing concerns related to privacy. Read the full post

The Era of Big Data

It never ceases to amaze me how while everyone is looking for the next big thing, it quietly sneaks up unnoticed all around us. I remember when after the cellphone revolution everyone was looking for the next killer app, predicting amazing things, and then it turned out to be teenager driven SMS texting. And who really saw the coming social networks revolution until we were immersed within it. Not me. And now it is happening again with Big Data.

“Big Data” refers to the mining of the truly massive data sets that now exist in the cloud to come up with new insights. An example frequently used is Google’s Flu Trends map. By mining internet searches, and where and when they occur, the internet search provider is able to map out flu prevalence even before doctors report the cases and the CDC analyzes the resulting data. But this is just an early foreshadowing of what will be possible in the future. Read the full post
