Intel announced the FM6700 chipset at the Intel Developers Forum in Sept and I missed this particularly interesting piece of information that will upset the OpenFlow haters: For the SDN networks, the FlexPipe frame processor can be used to parse and process SDN packets. The switch also supports 4,000 complete OpenFlow 12-tuple table entries that […]
In a recent discussion someone asked the relatively simple question “What does Programmable Networking even mean ?” and, after I stumbled around trying to explain, agreed to write something that attempted to explain what I see as the basic requirement that networking has not met. Here are some ideas just jotted down to open the discussion a bit wider.
Response: Three Bits of Advice From Discussing the Impact of VMware’s NSX at VMworld | IT Connection Blogs
This article from Mike Fratto at Current Analysis is great observation. Here is my view on the core topic: Networking vendors need to embrace homogeneity—that’s my first bit of advice—and present the most homogenous network to the virtual environment they can. By being homogenous, enterprises can swap out networking with far less disruption than having […]
VMware NSX got it’s official launch this week at VMworld. As a measure of how important VMware regards NSX, the first keynote on the first day is Martin Casado doing the official presentation.
My general view is the NSX is the real deal. I have been talking and writing about OpenFlow since May 2011 and many have complained that SDN isn’t important and I should focus on real network issues. Well, it should now be clear that SDN is a serious strategy issue and we might have been ahead of the market.
I wrote a white paper for Nuage Networks that is the first Packet Pushers White Paper. Nuage Networks have announced their version of SDN and I think it’s solid vision of what Software Defined Networking will become over the next couple of years – tunnel fabrics, software network agents in the server with load balancing and routing capabilities and controller/application software that can manage multiple data centres and their WAN networks.
Jump in and take a read.
I’ve been very busy lately with several large analyst/research writing projects so less links than usual this week. It will be sometime before I return to a more regular blogging schedule. You should check out Packet Pushers in the next few days where we will be launching a new feature – we are writing our own […]
Looking at using SDN & OpenFlow to perform a firewall migration on a rule by rule basis instead of using any of the other nasty, crufty hacks. Very useful when you want to find an easier and low risk way to get rid of those pesky CheckPoint firewall products.
Nicira is attempting to explain why they have chosen to use Open vSwitch Database protocol to configure network devices. By network devices, I mean virtual switches because I read this article as “we are making our own standars & API for configuring devices”. My question is why? There is a requirement to configure network device itself, […]
Here is an example of an SDN Application using the Big Switch OpenFlow controller to provide flow monitoring of your network. Stace Hipperson from Real Status has linked their HyperGlance 3D visualisation tool to capture flow data and display it in an quite useful way. Watch the video and consider what this means for troubleshooting a path […]
Over the weekend I published the latest Packet Pushers show about Software Defined Networking in the Priority Queue feed which focussed on Cisco and how you can implement SDN in an EXISTING network with some of key people from Cisco.
As I was editing the show I realised that the first time we discussed OpenFlow was in May 2011 on Show 40 – Openflow – Upending the Network Industry – a show where we identified that the future of networking was going to change. I can remember clearly during the discussion with Matt Davey from Indiana University being struck by how obvious the idea was. It was obvious to me that once you grasped the technical concepts behind OpenFlow , any decent engineer can perceive the impact on networking. While OpenFlow makes sense, it took another six months before Software Defined Networking became a thing.
Strap yourself in, SDN is just starting and it’s going to be a fun ride.
