Presentation Abstract:

Highly Available, Performant, VXLAN Service Node

VXLAN is a point-to-point, UDP-based "tunneling" protocol, which enables L2 encapsulation over an L3 "undernet", while also allowing up to 16 million Virtual Networks. One challenge with deploying VXLAN is that, by default, VXLAN requires multicast support for Broadcast, Unknown, and Multi-cast packets. Often this is not possible in customer networks. An alternative approach is to use the Service Node concept where dedicated node(s)/process(es) are responsible for flooding Broadcast, Unknown, and Multicast packets throughout a network.

This removes the need for multi-cast and greatly simplifies network configuration. However, it does require a scalable and highly available implementation.

In this presentation, join David Lapsley, Engineering Manager, Cisco/Metacloud, as he:

• Briefly reviews the VXLAN protocol and architecture

• Describes the (short) journey from a software-based proof-of-concept to HA and performant implementation utilizing open source technologies that implement VXLAN processing and highly available, replicated distributed caching

• Offers a cool demo!

Speaker Bio:

David Lapsley leads the Metacloud Engineering team within Cisco Advanced Services. David’s background is in networking, cloud computing, data visualization, software as a service, and user experience. David has been using Python for over 10 years and Django for 5 years. His first commercial Python project was writing a Spread Spectrum Software Defined Radio application for NASA. His first commercial Django project was the front end for a CyberSecurity product developed for Carrier-grade VoIP networks. David's career has taken him from graduate school in Melbourne Australia, where he studied advanced congestion control algorithms in packet switched networks, via the networking and telecommunications industry, advanced network research for NASA, DHS, DARPA and other government agencies, and finally on to OpenStack. David's work on OpenStack has been primarily on Horizon and Neutron, but he enjoys working on all aspects of OpenStack.
