Software automation and data analytics are changing the face of computer networks. They are radically transforming how networks are built and operated. We are rapidly moving away from a world where a network operator manages tenths of network devices. Instead, one individual can deploy and manage hundreds, thousands and tenths of thousands of complex network devices with the help of software and data analytics (what is your current ratio?). This transformation is quickly spreading from its birthplace, the data center, to all places in the network. To help accelerate these changes, we introduced significant software innovations for cloud Scale networking in Cisco IOS XR last year. A main component of those innovations is model-driven programmability.
The new programmability capabilities in Cisco IOS XR provide a rich and flexible infrastructure for network automation. What makes them rich and flexible? Read More »

Back in 2011, web pioneer Marc Andreessen wrote an op-ed in the Wall Street Journal, entitled “Why software is eating the world”. I couldn’t agree more!
First, let’s have a look at what’s going on in the industry at large. Every company in every vertical industry is facing unprecedented competitive pressure from new players making innovative usage of software and data analytics. It forces companies to embark on a digitization journey, which ends up having profound consequences on network infrastructure.
Great, so what does it mean to the network and to you?
The network infrastructure is Read More »

Carl Moberg from Tail-f covers NSO on TechWiseTV
This is the first in a new series of Service Provider focused topics. We had a lot of choices on where to start but this jumped out as my favorite. Tail-f brought us some incredibly successful work that dovetails nicely into our SP strategy.
Tedious CLI and home-spun scripts continue to characterize a boom of network growth that is now struggling under its own weight. SP networks, and many enterprises in fact, just can’t keep up with the demand for services. This now affects their ability to compete and thrive.
It has been impossible to implement network management and/or automation from the outside in. Even if our networks were all from one single vendor, the number of updates, traffic characteristics and unique configurations would still make it an uphill battle. SP networks are multivendor and full of legacy equipment that continues to have value. Cisco’s NSO is now offering a way to work this problem from the inside out. Standards and protocols that have been grown and tested over the last decade are now ready to turn this into one of those great ‘why didn’t we do this before’ situations.

The “P” in EPN stands for “Programmable,” as in “Evolved Programmable Network” and Cisco has just made the “P” easier to achieve to help drive services to the cloud. We’ve now contributed Basic ConfD, a free version of our powerful ConfD by Tail-f management agent software to the networking industry. Tail-f joined Cisco last summer and this announcement demonstrates Cisco’s commitment to not only embrace but also drive open standards in the best interest of the entire ecosystem. Read More »

As the IETF (Internet Engineering Task Force) meets in Hawaii (IETF 91), the unavoidable question for both participants and observers is whether a Standards Development Organization (SDO) like the IETF is relevant in a rapidly expanding environment of Open Source Software (OSS) projects.
For those new to the conversation, the open question is NOT whether SDOs should exist. They are a political reality inexorably tied to trade policies and international relationships. The fundamental reason behind their existence is to avoid a communications Tower of Babel (with the resulting economic consequences) and establish governance over the use of global commercial and information infrastructure (not just acceptable behavior, but the management of resources like addressing as well). Rather, the question is about their role going forward in enabling innovation.
SDOs (like the IETF) have to evolve their processes Read More »
