Video: SPB Deep Dive

24 March 2017

During the Leaf-and-Spine Fabric Designs webinar Roger Lapuh from Avaya explained how Avaya uses SPB technology to build a L2+L3 fabric.

Video: Out-of-Band SDN Management Network

10 March 2017

One of the challenges of designing a controller-based solution is the transport network used to exchange information between controller and controlled devices. Can you do that in-band or is it better to have an out-of-band network (built with traditional components)? Terry Slattery explained some of the pros and cons in the Monitoring SDN Networks webinar.

Newer Docker Networking Options

23 February 2017

In the last part of the free Docker Networking Fundamentals webinar Dinesh Dutt described the newer high-performance networking options (Macvlan and Ipvlan) introduced in Docker version 1.12.

Video: Simplify BGP Configurations

10 February 2017

Running BGP instead of an IGP in your leaf-and-spine fabric sounds like an interesting idea (particularly if your fabric is large). Configuring a zillion BGP knobs on every box doesn’t.

However, BGP doesn’t have to be complex. In the Simplify BGP Configurations video (part of leaf-and-spine fabric designs webinar) Dinesh Dutt explains how you can make BGP configurations simple and easy-to-understand.

Multi-Host Container Networking

20 January 2017

Running Linux containers on a single host is relatively easy. Building private multi-tenant networks across multiple hosts immediately creates the usual networking mess.

Fortunately the Socketplane team did a pretty good job; for more details watch the video from Docker Networking Fundamentals webinar or listen to the podcast I did with them a year ago.

Video: SDN Controller Running in a Virtual Machine

15 December 2016

During the Monitoring Software-Defined Networks webinar Terry Slattery addressed an interesting question: what happens if you run an SDN controller in a virtual machine and the virtual network crashes?

Want to know his take on the problem? Watch this free video on ipSpace.net content site.

Building a L3-Only Data Center with Cumulus Linux

2 December 2016

Dinesh Dutt was the guest speaker in the second Leaf-and-Spine Fabric Design session. After I explained how you can use ARP/ND information to build a layer-3-only data center fabric that still support IP address mobility Dinesh described the details of Cumulus Linux redistribute ARP functionality and demoed how it works in a live data center.

Video: Docker Networking Options

18 November 2016

After introducing the fundamentals of Docker networking, Dinesh Dutt focused on various Docker networking options, including multi-host networking with overlays.

Basic Docker Networking

21 October 2016

After explaining the basics of Linux containers, Dinesh Dutt moved on to the basics of Docker networking, starting with an in-depth explanation of how a container communicates with other containers on the same host, with containers residing on other hosts, and the outside world.
