Welcome back! We take things to the street in this episode of Engineers Unplugged. Ronald Beck (@tallnetninja) and Mark Gonsalves (Cisco) discuss real world two-way communications when there are radio interoperability challenges. Enter IPICS server and the policy engine. Because you really want comms in the field to work. This is a great episode full of real-world examples, let’s watch:

Welcome to Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:
Episodes will publish weekly (or as close to it as we can manage)
The “We’re Listening” blog keeps you in the loop about what Cisco is hearing from our customers and partners, and what we’re doing to address your top pain points. Teams across Cisco work together to fix these areas of concerns, and in this blog, you’ve heard from some of the experts who lead the improvement efforts. At the center of their efforts is Cisco’s Ease of Doing Business program, which looks at all the customer and partner feedback from surveys, individual meetings and conferences to determine the biggest pain points, and then pulls in the right people from across Cisco to make change happen.
The Ease of Doing Business team recently returned from Cisco Live, where they captured valuable feedback from our customer and partner attendees. I’ve asked Steve Morrisey, who leads the program, to summarize his top moments from Cisco Live, and to give us a hint at the changes we have in the works.
With the emergence of the Internet of Things (IoT), technology has become an integral part of our daily lives and promises to become even more prevalent in the near future. While this is normally a good thing – making our lives easier and more comfortable, any technology can be just as easily turned against us if it hasn’t been properly secured. In fact, there seems to be a direct correlation between the value of a connected object in our daily lives and the degree of pain inflicted if that object falls prey to hackers. Two recent articles in well-known publications highlight this fact.
Because IoT puts technology closer to home than ever before, much more is at stake than with prior networks. As a result, the need for proper security can’t be emphasized enough.
Despite all the buzz about software-defined networking (SDN), many organizations don’t yet have a clear idea of how it will benefit them. In this blog, I’ll tackle the what and why of SDN, and explain the different approaches you can consider.
What: A Disruptive Approach to Network Control
For the last quarter century, network devices have performed two types of processing:
The data plane looks at a routing table to decide where to forward packets. This processing takes place in dedicated hardware ASICs.
The control plane takes care of everything else, such as spanning tree, AAA, exporting NetFlow statistics, SNMP, and more. The control plane is implemented in software, and you can think of it as the brains of the network element.
So, if your network includes 200, 2000, or 20,000 network devices, that means you’re managing 200, 2000, or 20,000 control planes and keeping all of them up to date. Read More »
