[fancy_header3 variation=”orange”]SDN, OpenFlow and OpenDaylight Updates and Recordings[/fancy_header3] It’s been a busy few weeks in the SDN debate. I am posting some SDN updates from April along with some recordings from various events. The Open Networking Summit held its event. Only a few of the videos have posted so far. The keynotes and presentations that… Continue reading SDN, OpenFlow and OpenDaylight Updates and Recordings

Putting Together Provider Bridging, Provider Backbone Bridging, S-Tags and C-Tags
[fancy_header3 variation=”orange”]Putting Together Provider Bridging, Provider Backbone Bridging, S-Tags and C-Tags[/fancy_header3] Putting Together Provider Bridging, Provider Backbone Bridging, S-Tags and C-Tags: Understanding carrier bridging techniques is important, not just for provider operators, but also for engineers on the customer edge. When turning up or troubleshooting a circuit, carrier operators will ramble off C-tag and S-tag… Continue reading Putting Together Provider Bridging, Provider Backbone Bridging, S-Tags and C-Tags
OpenFlow: SDN Hybrid Deployment Strategies
[fancy_header3 variation=”orange”]OpenFlow: SDN Hybrid Deployment Strategies[/fancy_header3] 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… Continue reading OpenFlow: SDN Hybrid Deployment Strategies
OpenFlow: Coarse vs. Fine Flows
[fancy_header3 variation=”orange”]OpenFlow: Coarse vs. Fine Flows[/fancy_header3] 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… Continue reading OpenFlow: Coarse vs. Fine Flows
SDN OpenFlow Policy Abstractions
[fancy_header3 variation=”orange”]SDN OpenFlow Policy Abstractions : Frenetic Netcore Procera[/fancy_header3] 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… Continue reading SDN OpenFlow Policy Abstractions
The Control Plane, Data Plane and Forwarding Plane in Networks
[fancy_header3 variation=”orange”]The Control Plane, Data Plane and Forwarding Plane in Networks[/fancy_header3] The Control Plane, Data Plane and Forwarding Plane in Networks is the heart core DNA in today’s networking hardware to move IP packets from A to Z. The Management plane is another vital component but also widely excepted as user to hardware interaction. These… Continue reading The Control Plane, Data Plane and Forwarding Plane in Networks
The Best MPLS Lecture on the Net
[fancy_header3 variation=”orange”]The Best MPLS Lecture on the Net[/fancy_header3] The Best MPLS Lecture on the Net: The title says it all. Professor Karandikar gives two amazing lectures on MPLS and MPLS-TE that most engineers should hope to know cold. I watch it probably once every few months. Not saying much for my memory these days. It is… Continue reading The Best MPLS Lecture on the Net
Ethernet Switch Fabric Cards
I was working with a buddy today about ethernet switch fabric cards in the nexus 7000 and not doing a very good job at explaining it, so I figured I would draw some pictures. The conversation was around how adding more fabric cards increases the bandwidth. I think some, myself included growing up on Catalyst… Continue reading Ethernet Switch Fabric Cards
