Title: Freestyle 104 - Cisco SD-WAN (aka Viptela) Design



Episode video: https://youtu.be/qL4rwAmG-dI

Published: 24th January 2019

Hosts: Malcolm Booden, Daren Fulwell

Guests: None

In this episode Malcolm and Daren discuss the design principles, building blocks and behaviour of Cisco's SD-WAN product.  Formerly Viptela, Cisco acquired the product in mid 2017 in order to develop their software-defined networking capabilities.

Cisco SD-WAN is a fully-featured integrated software-defined networking product, which uses many concepts which will be familiar to the viewer, and others that are less so.  We bring the practical experience of designing such networks to the video and discuss some of the pitfalls and gotchas experienced along the way.

In this episode Malcolm and Daren discuss data centre design, covering the key building blocks required to deliver a modular and scalable solution.

The design topics covered throughout the discussion include the trusted, semi-trusted and untrusted zones of the data centre, design drivers and some scenarios relating to traffic flows to / from applications and services from the WAN and internet.  

Consequences of stateful devices in the failover path are also covered with some suggestions on how issues can be alleviated to avoid application outages.
