The Future of F5 Networks: SDN, iRules & Node.js
Unlike some others in the network industry (until lately at least), those dealing with F5 Networks’ products are probably well accustomed to change – significant and fast paced change at that. F5 are not a company to shy away from rapid change and replacing old technology and tools with newer, better ones. The change from the […]

Show 142 – Huawei – End to End SDN Strategy – Sponsored
SDN innovation has been primarily focused on the data center where centralized network programmability has been shown to be capable of providing many benefits to the complex and dynamic (on-demand) data center environment. Service provider networks will also benefit from SDN. Traversing a service provider network involves crossing different network types, technologies, layers and administrative domains. SDN solutions, including OpenFlow’s programmatic control, will provide capabilities unique to these service provider technologies. Huawei presents an architecture that expands SDN into multiple, task specific, controllers and domains and extends networking control across all of the service provider network dimensions.

A Small Yellow Wooden Door: Thinking Practically About SDN
As I do most days, I took a walk in the woods at the back of my garden after a hearty dinner. I was quite surprised to come across a small wooden yellow door I’d never seen before, set into the trunk of a tree I’d never noticed until today. I opened the door and squeezed […]

Handling Tech Support Interaction Effectively
Network engineers deal with technical support frequently. That’s the nature of the networking business: the products often don’t work as advertised or break down under their own complexity. Throw in some ambiguous documentation that leaves you scratching your head, and you’ll finally resort to opening a case with the vendor to resolve the issue. In […]

The Man in the White Suit
I know this is a technical blog, but I’ve always agreed with those that believe the best way to deliver a message is through a story. As imaginative and creative as I feel I can sometimes be, writing fiction just isn’t one of my strong points. So, rather than tell you an original story of my own I’m going to relate […]

When Am I Going to Use This?
I imagine that prior to the industrial revolution, people didn’t struggle with niche skillsets that didn’t transfer. They didn’t need to wonder if they were spending countless hours learning something with no particular use outside their current job, listen to well-meaning friends and spouses assure them they’re worrying about nothing, only to face a layoff […]

Firewalls: Expensive, Broken Routers
In a previous post on IPS, I made a fairly negative comment on the value that you get from enterprise firewalls in the modern environment. At the time, I said that I was just going leave that comment hanging and see what happened. Well, precisely no one challenged me on it, which means either everybody […]

Using IP SLA Delay Feature to Safely Monitor Lossy Links
IP SLA is a great feature if you want to add some automation and intelligence into the network. SLA is no SDN/OpenFlow, but it can be very useful. It can also take down a network. Let’s say you are using DMVPN for a number of spoke locations in your network. You have a primary Internet […]

Surprised by Spam
I attended my first in person meeting of the ISOC Advisory Council this last week — I’m a newly minted co-chair, and already haven’t been participating as much as I should (just like I don’t blog here as much as I should, a situation I’m undertaking to resolve!). We had a long discussion on the […]

Six Things About F5 BIGIP v11 iApps
F5 Networks’ Local Traffic Manager (LTM) is my load balancer – okay, Application Delivery Controller, if you insist – of choice. The LTM platform is as feature-rich and well-supported as they come, with all sorts of customizability as well as the iRule scripting language (a superset of TCL) that lets you do fancy transaction manipulation. […]

Show 140 – Introduction OpenStack and Quantum Projects
OpenStack is progressively developing into a product that networking needs to be a part of. One way to describe OpenStack is to say it’s an API for infrastructure. OpenStack is a combination of open source plus a significant number of hardware vendors who see contributions to OpenStack as a way of growing or maintaining their own markets and customers.
Customers want OpenStack as an alternative to VMware or other commercial software - not all applications and service need to have expensive software licenses and maintenance. We need to be able to build a core of functional services that can deliver services.
In the future, it seems likely that OpenStack Quantum API will be important. We discuss Open Vswitch and how it’s changing from being a “switch” to including routing, firewall and load balancing features. If you don’t like that, you could consider using Quantum API as a way to consume load balancers from your preferred vendor - the API exists to simplify the consumption of network resources.

What’s Next for OpenFlow and Open Source?
One year ago, the Open Networking Foundation was setting a blistering pace of standards development. Though their process is closed to outsiders, word had leaked out that not only were they on track to produce version 1.3 of the OpenFlow standard, but 1.4 would follow before the end of 2012. At some point that plan […]
