OpenFlow Supports IPv6 Flows

OpenFlow is a Software-Defined Networking (SDN) protocol used for southbound communications from an SDN controller to and from a network device. OpenFlow is the protocol used to inform the topology of network switches on which flows should be added to their flow tables and advise switches how they should handle traffic flows that are not in the current flow tables. Initially, OpenFlow did not have any definition for handling IPv6 communications. Now, newer OpenFlow versions have IPv6 capabilities and more vendors are deploying products that use the newer OpenFlow versions. This article goes over the IPv6 functions within the OpenFlow protocol and describes how these are being used.

Migrating email from Exchange (on-premises) to Office 365 (in the cloud) would seem to be a pretty simple and straight forward process, and when you know what you are doing, it is a methodical process. However in the past 2-3 years that we've been doing Office 365 migrations, it's amazing the number of times we get called in to "fix something" that some other migration specialist did that has us shaking our heads wondering what they were thinking...

Facebook's icky psychology experiment is actually business as usual

Unless you've been living under a rock for the last couple weeks, you've no doubt heard about Facebook's creepy, secret, psychological experiment designed to see if negative newsfeed posts inspire more negativity -- and vice versa. I don't want to excuse Facebook's behavior, which has prompted a (sort-of) apology from Facebook COO Sheryl Sandberg, as well as an ongoing stream of condemnation and outrage from legitimate psychologists and Internet commentators. I too was weirded out by the revelations, feeling manipulated and that somehow my privacy had been unfairly invaded without my permission.
