VIRL Saves the Day!

One of the themes of my posts is that the overall ONE strategy, including virtualisation, would create an environment for network systems development that would meet the expectations of systems developers accustomed to the “enterprise” style of software development. An enterprise systems developer expects the required systems resources for software development to be readily available […]

Simplifying Multi-Provider WAN Designs

This week, at Cisco Live Orlando, we are introducing a brand new EIGRP feature called Over-the-Top (OTP). EIGRP OTP is focused on simplifying the deployment of branch networks utilizing an EIGRP end-to-end solution over public and private networks. This simplicity is further enhanced with EIGRP use of Over-the-Top (OTP) to support multiple service provider IP networks. […]

The “Business” of Software Defined Networking

I admit it. I’ve grown weary of the debate about whether SDN includes network programmability or whether or not SDN can only be accomplished through NfV, or the relative merits of control plane / dataplane separation. I will leave those debates to others more focused on the technology itself.  Personally, I have been more fascinated […]

Blogging Journey from Cisco Live from Cisco ONE: Intelligent Programmable Network

Cisco Live is here! It’s a great opportunity for you to discover some really exciting technology solutions at our Cisco ONE: Cisco Intelligent Programmable Network booth featuring a few of our latest innovations. Onsite you will be able to see and ask your questions at live demos featuring applications and services developed with One Programmable […]

OpenDaylight: Understanding the Value Propositions

The announcement today of OpenDaylight is big news.  Industry leading companies are partnering via Open Source to serve an emerging set of market needs: Operators: want affordable real-time orchestration and operation of integrated virtual compute, application, and network. Application Developers: want a single simple interface to the network.  Underlying details such as “router”, or “switch”, or “topology” can be a distraction they desire […]

Infrastructure Software: SDN makes network management a first class citizen

Back in May 2012 Mike Fratto predicted in his blog that SDN will be “Reborn in Network Management”. There is a lot of truth to his statement. The words “software defined” in “Software Defined Networking (SDN)” inspired people to rethink the overall control plane architecture of the network making the case for infrastructure software that […]

SDM: Software Defined Manageability

Much has been made of the emergence of Software Defined Networking and the programmable network.  At its core, SDN involves opening up network interfaces in order to make the network programmable and allow for the development of applications.  While some of those applications interact directly with the data plane, determining how individual packets are treated, […]

Cisco Opens Up EIGRP

What’s new and exciting with EIGRP (Enhanced Interior Gateway Routing Protocol)? Actually, lots…  First a bit a background on EIGRP. EIGRP is an advanced distance vector routing protocol used extensively by enterprise customers.  It is very popular because it is simple to deploy and support. Some major attributes are: EIGRP does not mandate many network design […]

A week in my life at Cisco Live London

It is not often you get a peek in the behind scenes of the Cisco Employees who put their personal lives on hold to support a major event like Cisco Live.  I am very sure this blog will not do justice to sharing one person’s perspective, but lets give it a try shall we?
