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.

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.
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?
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.

Optimize Your Data Center: How Far Did We Get?
4 November 2016
Our Data Center optimization journey has finished. We virtualized the workload, got rid of legacy technologies, reduced the number of server uplinks, replaced storage arrays with distributed file system and replaced physical firewalls and load balancers with virtual appliances.
Let’s see what’s left: it turns out you really don’t need more than two switches in most data centers.
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.
