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.

How to effectively manage the integration of IT/OT in the hyper-connected enterprise

There has been a lot of discussion lately about the Internet of Things (IoT) and how connected endpoints can help revolutionize the way businesses collect and process information from Operational Technology (OT) systems, but there are huge challenges in accessing the information and making it accessible to your other business systems, employees and business partners.

Promise Theory

The way we have created IT systems over the years has been very linear with each individual component being statically configured. If a human makes an error in any one of the many configurations, then the whole system breaks down. Over the years, IT systems have become increasingly complex with multiple layers of abstraction and virtualization making it difficult to enforce stability and gain scalability. Promise theory provides a new way to think about how IT systems rely on each other to form an entire system that businesses can depend. This article will cover the foundation concept of promise theory and give examples of how it is used.

And there's something else wrong with Comcast's Xfinity customer-based Wi-Fi hotspot plan ...

I have, in previous Gearhead articles (first in Comcast's latest bad idea turns your Wi-Fi into everybody's Wi-Fi and then in Revisiting Comcast's Xfinity public hotspot strategy), discussed Comcast's strategy for implementing opt-out Wi-Fi hotspots on their customers' Xfinity gateways. In the latter post I questioned the security of the service and noted that access to the Comcast service isn't as tightly controlled as the company might think.

The PSTN transition to VoIP: Going green

We've discussed some of the advantages of transitioning the PSTN to IP, but there we haven't yet covered the environmental implications of the pending transition. At their annual partner conference Perspectives14, GENBAND hosted a discussion which addressed the power costs behind the PSTN, pointing out the benefits an IP transition.

Hungry ants knock out FiOS service ... again

Everyone keeps asking if the ants actually ate their way through the fiber optic cable and I do not know the answer. What is certain is that they chewed through the outer casing and caused enough damage to knock out TV, phone and Internet service to my house: the Verizon triple no-play.

Microsoft introduces Interflow: Sharing cybersecurity threats in near real-time

Microsoft announced Interflow, a new platform for sharing cybersecurity threats in near real-time. Although it's currently available only in "private preview" for Microsoft Active Protections Program (MAPP) members, security threat information will be shared faster, creating a "collectively stronger cybersecurity ecosystem." In the long run that means protecting people better and more quickly.

Why Facebook's SDN switch won't affect Cisco's customers

Last week, Facebook announced a new product that's supposed to have the networking industry trembling. There were many news stories about Facebook's new homegrown SDN switch, known by the codename "Wedge" that's supposed to be the next big threat to Cisco and the traditional networking vendors. The operating system on the product runs Facebook's proprietary version of Linux called FBOSS.
