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 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.
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.
I doubt that anyone bought a Vblock because it was a market leading networking strategy. I’ve been a supporter of VCE but today I’m doubtful that choosing Cisco ACI is good strategy for their customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a services package of fully supported storage, compute and networking that removes customer risk around VMware deployments while reselling EMC & Cisco hardware.
