The SDN Impact on Net Neutrality
Over the next 10 years the networking industry is going to transform much more than it has in the previous ten year. The catalyst as we know it today is called SDN. What SDN really means is, the time has come to bring networking into the same decade conceptually, as the rest of the computing world. Networking will move away …
OpenStack Multi-Node DevStack Nova Network Tutorial
DevStack is a scripted OpenStack installer maintained for developers to prototype and debug. It is also handy for operators to proof concepts and test new services and configurations. This is a good starter for folks new to OpenStack to help understand how to install and operate OpenStack. Some folks have been asking about multi-node DevStack deployment using nova network, so …
OpenFlow: SDN Hybrid Deployment Strategies
This series of posts, has been focused on reviewing some practical OpenFlow SDN deployment strategies. Early SDN, will be hybrid networks and early niche applications to begin understanding how to integrate pockets of SDN, mitigate risks and most importantly understand the technology to properly scale solutions. If you try and put 5,000,000 access-lists into a kit that can only do 2,000 …
OpenFlow: Coarse vs. Fine Flows
OpenFlow: Coarse vs. Fine Flows – This series of posts, is to shed light on some illogicalities surrounding the SDN discussion. I will highlight what I propose, will achieve performance and scale when implementing flow based forwarding designs. Soon these debates, will no longer be conceptual or limited deployments in only the hyper-scale networks, as more of us begin real-life implementations. …
OpenFlow: Proactive vs Reactive Flows
As more people begin entering the Software Defined Networking conversation, there is still only one wire protocol that has a reasonably good chance at becoming the de-facto open SDN southbound messaging standard, OpenFlow. There is quite a bit of debate around whether or not OpenFlow can scale. Most claims that OpenFlow does not scale are probably grounded in misconception. That …
SDN OpenFlow Policy Abstractions
SDN OpenFlow Policy Abstractions : Abstraction layers are a fundamental principle in computer science. It is a core pillar in creating efficiencies through layered, modular scale. Proper abstraction layers are also where the networking train came off the tracks. Network operators program network devices using proprietary APIs one device at a time. In today’s networks, when we push policy to …
Plexxi Capacity Planning Done Right
I try and get a daily dose of at least a few minutes of a PacketPushers podcast to keep up with latest networking products and trends. In Show 126 Plexxi & Affinity Networking With Marten Terpstra Greg and Ethan meet with Marten Terpstra of Plexxi and dug into the new GA product offering from Plexxi. Plexxi defines “affinitized traffic” as traffic …
Best Cat Videos of 2012
took a rare, but important intermission from technology related posts to write about the one and only thing cooler than computing, programming and networking, that is videos of cute cats and kittens! These are the best cat videos of 2012 that I remember watching this year. Pets love us unconditionally that can only come from pure innocence. As they depend …
