Tell me what you want, what you really, really want: Intent-Based Networks and the rise of Domain Specific Languages in Networking

IEEE CTN Issue: July 2017

This month we take a quick look at the role of domain specific languages in future telecoms networks, prodded into this topic by Cisco's recent promotion of intent based networks, which we argue are just another example of DSL.

Is the future of network management as simple as high-level policy statements? Where else do we see domain specific languages popping up in telecoms? We take a crack at answering these questions but your insights are always welcome in the comments section.

Where is 5G now?

IEEE CTN Issue: June 2017

We thought it was about time for an update on the 5G standard progress. 5G is getting close to prime time which will occur perhaps as early as 2019 with the US leading the charge with fixed wireless to the home being a big initial application for 5G. In this article we give a brief summary of the features that have settled in to the 5G standard and also present a few demo and trial results. All the 5G nerds out there are welcome to write in and tell us what we missed.

Close Enough to Correct: Approximate Computing

IEEE CTN Issue: May 2017

With the release of the Google Tensor Processing Unit paper we discovered that the cloud services folks were seriously thinking about fixed point computation. This is interesting because the DSP world, including the part that serves the wireless space, has made a significant effort to move towards floating point over the last decade. We could discuss the reasons for this switch at length but it is clear that it mostly comes down to ease of programming and a desire to minimize the power and area of computation. So this month I wanted to examine other ways of being approximately correct and saving some power and area in the process, aka approximate computing. In this article Prof. Ben Schaefer of UT Dallas will give us a quick look at how things work and the risks involved in ripping out gates and wires in an attempt to save some power. Your comments and questions are, as always, welcome.
