Every network operations center (NOC) manager dreams of the day when he or she can relax on the beach without worrying about monitoring or maintaining their network. Or, more realistically, NOC managers are waiting for the day that they can put the network on autopilot, freeing up their time and resources for more ‘meaningful’ tasks.

As apparent in the OPNFV summit held a couple months ago, network functions virtualization (NFV) is taking off in terms of popularity. While, the growing interest hasn’t quite been translated into widespread deployment, the underlying concept is obviously building a very wide and diverse fan base. Along with the interest, the list of potential and real inhibitors also keeps growing.
The current state of the mobile network isn’t as clean as you might hope, as marketers push the benefits of the latest and greatest 4G LTE technology and upcoming 5G capabilities. In fact, adapting to the mobile network evolution is a messy proposition that even the most advanced service providers can struggle with.
Despite the flashy promises of advanced 4G LTE and 5G networks, service providers must find more effective ways to improve service quality across multi-generation mobile networks.

The first Big Communications Event related blog focused on Virtualization and Security. In this entry, the focus is on the other hot topics at the show, specifically Automation and Disaggregation.

In my last blog post, I considered two questions: what does a control plane really do, and what does a forwarding device really look like? Before continuing to our final destination—a better understanding of what an SDN is, and what the fuss is all about—we need to back up to the first post in this series, and reexamine the question of centralization and decentralization.
Until recently, open source has had a relatively modest impact on networking. One of the many indications that open source is now having more of an impact on networking occurred at the 2016 Open Networking Summit in Santa Clara, CA. In past years, the focus on the ONS was SDN and NFV. While those were important topics at this year’s conference, the tag line for the conference was “A New Era of Open Source Networking”. The fact that this year’s ONS had such a strong focus on open source shouldn’t be surprising because in November 2015 the ONS became a Linux Foundation event.
The LightReading Big Communications Event (BCE) for 2017 was held May 24th and 25th in Austin, Texas. The attendees list was strong and the presentations were certainly worth the cost of admission. The show presented a microcosm of the significant issues and themes confronting the telecommunications industry as a whole, with a significant focus on virtualization of network functionality. Other major themes of the show included security, automation, and disaggregation. All of these topics showed up throughout vendor and service provider presentations alike.

“Think specifically about the OTT (over the top) Cloud applications that run on the infrastructure you provide: Facebook, WhatsApp, Skype, Google Maps and more. You provide the infrastructure, the satellite links, the entire spectrum of network services (security, backup, bandwidth and more) . . . and OTT apps use it all to siphon revenue from you with lower-quality and often-free apps—from messaging to navigation to telephone.”
When the Shannon Limit was set forth in the mid-1900s governing the theoretical limit of information carrying capacity of a communications channel, it was impossible to imagine that this would someday be applied to fiber optics communications that was not even conceived of at that time.

Up until the late 2000s, implementing carrier-grade security solutions involved a great deal of struggle and multiple appliances were installed all over the network. Ordinary servers weren’t built to handle the resource-intensive software that would monitor and protect your network. In the modern day, COTS servers have greatly increased their capabilities, allowing complex applications to run on general-purpose computing machines. The next obvious step is to run network security applications using NFV.
