Overlay Networking and Coarse Flow Table are two ways to scale up the flow networking for SDN.
A constant refrain from vendors and software makers is that OpenFlow technology doesn’t scale, is too complex, and doesn’t work in hardware. Startups like Corsa are proving them wrong.
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’ ?
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.
Facebook has telling people more about it’s in-house designed and developed whitebox Ethernet switching based on Broadcom silicon (not sure if it’s Trident2 or Arad), their own Linux distribution and OpenCompute standards.
An explanation of the difference between SDN, Automation and Orchestration.
