It’s Our Time Down Here– “Underlays”

Joe Onisick (@JoeOnisick), July 14, 2013May 18, 2020

Recently while winding down from a long day I flipped the channel and “The Goonies” was on.  I left it there thinking an old movie I’d seen a dozen times would put me to sleep quickly.  As it turns out I quickly got back into it.  By the time the…

Focus on the Ball: The Application

Joe Onisick (@JoeOnisick), July 1, 2013May 18, 2020

With the industry talking about Software Defined Networking (SDN) at full hype levels, there is one thing missing from many discussions: the application. SDN promises to reign in the complexity of network infrastructure and provide better tools for deploying services at scale. What often seems to be forgotten are the…

Network Abstraction and Virtualization: Where to Start?

Joe Onisick (@JoeOnisick), June 19, 2013May 18, 2020

Network Abstraction and Virtualization: Where to Start? With the growth of server virtualization network designs and the associated network management constructs have been stretched beyond their intended uses. This has brought about data center networks that are unmanageable and slow to adapt to change. While servers and storage can be…

What Network Virtualization Isn’t

Joe Onisick (@JoeOnisick), June 8, 2013May 18, 2020

Brad Hedlund recently posted an excellent blog on Network Virtualization.  Network Virtualization is the label used by Brad’s employer VMware/Nicira for their implementation of SDN.  Brad’s article does a great job of outlining the need for changes in networking in order to support current and evolving application deployment models.  He…

I’m feeling Seussish again and looking to tackle SDN this time.  If you missed my first go it was on Hadoop: Horton Hears Hadoop.  Here’s another run:   The app could not flow Net was too slow to change. It sat on the server Waiting on admin for change.  …

Network Overlays: An Introduction

Joe Onisick (@JoeOnisick), December 13, 2012May 18, 2020

While network overlays are not a new concept, they have come back into the limelight, thanks to drivers brought on by large-scale virtualization. Several standards have been proposed to enable virtual networks to be layered over a physical network infrastructure: VXLAN, NVGRE, and SST. While each proposed standard uses different…

Why We Need Network Abstraction

Joe Onisick (@JoeOnisick), November 27, 2012May 18, 2020

The move to highly virtualized data centers and cloud models is straining the network. While traditional data center networks were not designed to support the dynamic nature of today’s workloads, the fact is, the emergence of highly virtualized environments is merely exposing issues that have always existed within network constructs….
