No. When compared to the operation of existing networks, SDN is much more secure.
When using Open Daylight (ODL), two open standards for configuration are OpenFlow & NETCONF. Which is the better choice ? Is there an option for both ? A use case on when to use OpenFlow and NETCONF protocols in the Enterprise by using the best features of each protocol.
I’ve been reading the Cisco Application Centric Infrastructure Design Guide. Sometimes I see a product of genius and wondrous use of technology, other times I’m like ‘did they do it the hard way or what’ ?
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.
There are many algorithms that can be used to for flow-based hashing to provide the best load balancing method over multiple IP or Ethernet connections but I recently learned that Cuckoo Hashing the preferred method.
Here is a block diagram showing the functional areas in private & public cloud that I use when working with clients. I’m often explaining the full picture of cloud building especially in relation to how the network can be orchestrated to fully accelerate the cloud process. I hope you find it useful.
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.
Lots of people claiming that scripting works for automation and, for a few scripts or tasks, you can get a lot done for not much effort. My experiences with scripting have left me bitter and jaded. Here is why.
