OpenContrail and Kubernetes

September 24th, 2018
Written by Curtis Collicutt

OPENCONTRAIL AND KUBERNETES Editors note: After this article was written the OpenContrail project changed its name to Tungsten Fabric. Software Defined Networking (SDN) exploded onto the scene in and around 2008, in part due to the creation and popularization of OpenFlow. While OpenFlow did not specifically cause the development of SDN, it was certainly a…

NFV MANO – OpenBaton

September 17th, 2018
Written by Curtis Collicutt

NFV MANO – OpenBaton   Certainly in the last few months the Open Network Automation Platform (ONAP) has taken the lion’s share of publicity. But there are other MANO solutions, some commercial, some open source MANO. OpenBaton is an open source MANO that has most, if not all of the required features of a MANO…

One of the things we do at IDX is help organizations onboard Virtual Network Functions (VNFs). VNF Onboarding is an involved and complex process with many steps. One of the activities in our onboarding process involves the performance testing, verification, and dimensioning of a VNF. In this particular example we discuss testing a Domain Name…

What I Took Away from the 2018 Openstack Vancouver Summit

September 7th, 2018
Written by Curtis Collicutt

From May 21st to 24th of 2018 the OpenStack Summit was held at the beautiful, world class Vancouver Conference Center. Several IDX colleagues and I attended the conference, not only to take in talks by others but also to present research of our own. We were also fortunate to participate in the Edge mini-keynote on…

Blurred Lines: Containers and Virtual Machines

August 6th, 2018
Written by Curtis Collicutt

We know that containers are an important new technology (well, at least Linux containers are, there have been similar technologies in existence for some time). Docker based containers, still heavily utilized even in Kubernetes, build on Linux technologies such as cgroups and network namespaces to achieve isolation. However, other technologies can be “plugged in.” We…

It’s All About Dependencies

July 30th, 2018
Written by Curtis Collicutt

I have a pet theory that it’s all about dependencies. I work in an area, Network Function Virtualization, NFV for short, that is made up of many complex systems. The most obvious example is OpenStack, which is notoriously considered complicated. To be fair, there are many more high level systems like it that are also…

An Introduction to 5G Network Slicing

July 23rd, 2018
Written by Curtis Collicutt

A colleague and I gave a presentation entitled “5G Network Slicing and OpenStack” at the 2018 Vancouver OpenStack summit. We did a lot of research, reading 70 to 100 papers (whitepapers, standards body papers, academic papers, you name it–so many we published a bibliography) to try to determine what network slicing is and how OpenStack can…

Faking Service Chains at Layer 3

June 18th, 2018
Written by Curtis Collicutt

Faking Service Chains at Layer 3 In the last post we introduced the concept of Service Function Chaining (SFC). In that post we suggested that SFC occurs at the virtual port layer, somewhere around layer 1 of the OSI model. We can debate whether it is truly layer 1 or not, in part because SFC…

Introduction to Service Function Chaining

May 14th, 2018
Written by Curtis Collicutt

Introduction to Service Function Chaining Service Function Chaining (SFC), which I will describe in this post, is an important feature that arises out of Software Defined Networking (SDN) and Network Function Virtualization (NFV). SFC is most applicable to telecommunications companies or in security applications, but also has broader application. Currently the networking space is an…
