The Cisco ONE SDN Controller
Cisco announced the ONE controller at Cisco Live last summer. The ONE has been in Beta for a few months now. There is still plenty of fragmentation around what SDN is and what it should solve. One generally accepted concept is the way we operate networks today, is showing signs of age. The announcement of OpenDaylight this week, pretty much …
Installing OpenStack Grizzly with DevStack
Installing OpenStack Grizzly with DevStack is pretty painless. Grizzly will be officially released at the OpenStack Summit in a couple of weeks. There are some really impressive new network functions coupled with the OpenStack Grizzly release. DevStack is a handy tool for developers and people brand new to OpenStack. Keep in mind, the OpenStack install that DevStack performs is not …
SDN Dominates NFD#5
SDN was the soup dajoure at Networking Field Day #5 and rightfully so. My friends are not only talented bloggers, but also some of the best architects, engineers and operators in the networking field. The networking industry has gone without significant innovation since at least MPLS and arguably Ethernet. Our network architectures are snapshots of the cold war. Every device …
Big Switch Introduces Switch Light
Big Switch took a step towards rounding out their portfolio with introducing plans to release a software switching software to integrate into ODM (Original Design Manufacturer) and vendor hardware switches. The “thin switching” software is made up using the FOSS (Free and Open Source Software) Indigo project from Stanford University and Project Floodlight. Just as various vendors have used Open …
Be The Steamroller Not The Road
I always chuckle when I hear SDN or OpenFlow “bigots”. I find that it is normally vendors being flippant towards SDN in general are from a handful of camps: When people spend time to understand that OpenFlow is merely an open messaging protocol to instantiate flow based forwarding. Flow based forwarding integrates L4 into forwarding decisions. L4 adds rudimentary application …
The Good and Bad of Wireless
The Good and Bad of Wireless :A while back, I posted some numbers on campus 802.11 growth. Wether cellular or 802.11, the numbers are big. The numbers show in the 802.11 campus which reflects smart phones, tablets, laptops and soon to be glasses and watches painted all over people. In networking, customer growth typically linearly correlates into the need for …
Hybrid OpenFlow Using The Normal Action
Hybrid OpenFlow Using The Normal Action: When a new technology is introduced in networking, it is not uncommon for most to transition that new technology into their network for test/dev or production by starting with small chunks at a time. Hybrid OpenFlow deployments will used by many of us as a place to start with SDN with fairly low risk …
More Vendors Define Their SDN Strategy
It was a busy week in SDN. Some pretty significant revelations gave us good directional indications for SDN in 2013. Most significantly is SDN is getting enough traction to drive significant investment and tough decisions to be made by the networking incumbents. As more vendors define their SDN strategy, we will see an increasing amount of commercial products, rather than …
More Details About The Cisco ONE Controller Announced
Cisco has begun further unveiling more details about the Cisco ONE controller, currently in early beta. The announcement, specifies new SDN applications and hardware support for a select few existing products and new ones like the Catalyst 3850. Also recently announced, is the new Nexus 6000 switching product, along with a NAM module for the Nexus 7000. The Nexus 6000 is 96-ports …
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 …
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 …
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 …
Google Data Center Pictures: Year in Review
Google Data Center Pictures: Year in Review :In 2012 Google opened the doors up to some of it’s data centers in the typical colorful fashion we expect from Google. Hyper-scale content and cloud providers are ultra secretive about their trade secrets. Facebook’s Opencompute project is probably the most notable transparent architectures with regard to how they build their compute and …
