I collect data from three different research . This is much higher and sooner than my previous survey data in December 2013 and more recently for InformationWeek. Clearly, SDN demand is much greater than almost anyone predicts. Are people talking to the wrong sources about the future of networking ?
Big Switch Networks (BSN) launches Version 4.0 of Big Cloud Fabric for hardware-centric SDN data centre fabric. The Data Centre Fabric solution clearly shows the maturity gained from 5 years of shipping products while adding innovation in switch hardware through Switch Light operating system. At the same time, they have completed the transition from platform to product. A product that really has what you need in a hardware-centric SDN platform and addresses nearly all of the issues the competitors have not addressed. And it is shipping now.
I’ve been working on Mellanox S-Series switches lately in a largish network with several hundred 10GbE server ports. On the whole, the product has performed beyond my cynically low expectations and the product has good capabilities overall but the command line interface (CLI) is a really poor user experience. How about this gem for configuring […]
With the vast marketing budgets from big vendors and their well paid “evangelists”, the startups vying to introduce new methods and the clamour of engineers trying to understand new technology it might be time to pause and remember that Software Defined Networking was a customer-driven initiative. Vendors had to be forced to accept that SDN was a necessary change.
IETF RFC on the Standards Tracks that talks about the problem of chaining headers in IPv6. I’m getting a sense of deja-vu since this was also has issue with IPv4 and, ultimately, use of chained IPv4 headers died away. If they encounter an unrecognised extension header type, some firewalls treat the packet as suspect and drop it. Unfortunately, […]
The IP PBX business is shrinking as mobile phones replace desk phones. More importantly, voice calls are replaced with chat applications like Skype, FaceTime, SnapChat. Modern companies are using messaging platforms like Slack to replace time wasting telephone calls – we run the Packet Pushers business zero telephone calls. I’ve been predicting this for a year […]
Extreme Network now charges a license fee for ports that have 40G/100G OEM or third party SFPs installed. If you don’t purchase a license within 90 days, it will limit bandwidth to 25%. How crappy is that ? Hiding the full price of the switch in SFP pricing strategies is a dumb idea that all the vendors have, what about simply being honest and calling it what it is – a per-port licensing fee designed to extract more revenue from a shrinking market.
