New Ethernet technologies address evolving enterprise needs, including WLAN support.
During Cisco Live Europe (huge thanks to Tech Field Day crew for bringing me there) I had a chat with Jeff McLaughlin about NETCONF support on Cisco IOS XE, in particular on the campus switches.
We started with the obvious question “why would someone want to have NETCONF on a campus switch”, continued with “why would you use NETCONF and not REST API”, and diverted into “who loves regular expressions”. Teasing aside, we discussed:
Read more ...Our friend Cisco made a big announcement this week – “Cisco has built a new networking operating system that will allow users to run its most sophisticated networking features on older and lower cost Cisco routers and switches”.
We welcome and are in fact quite excited about this change. This validates the inevitable paradigm shift of the segregation of network hardware and software, and even a big titan like Cisco cannot stop the change.
If you can recall Cisco’s then-CEO John Chambers’ talk in 2015, Chambers dismissed SDN and white box makers, saying “We are seeing no unusual competition in the market, no unusual competition with white-label or white box [vendors], nor will we in the future.” Even in mid 2016, the new Cisco CEO, Chuck Robbins, still maintained the same tough position, stating “There’s a misconception that’s driving the belief that all customers want to buy white box switches”. That was less than a year ago, and the world has completely changed.
So Cisco has changed their opinion. The market is going through a paradigm shift, and I actually admire Cisco’s courage to embrace the changes instead of fighting them. Cisco has been leading the networking industry Continue reading
It’s easy when talking about the ongoing push toward exascale computing to focus on the hardware architecture that will form the foundation of the upcoming supercomputers. Big systems packed with the latest chips and server nodes and storage units still hold a lot of fascination, and the names of those vendors involved – like Intel, IBM and Nvidia – still resonate broadly across the population. And that interest will continue to hold as exascale systems move from being objects of discussion now to deployed machines over the next several years.
However, the development and planning of these systems is a …

Today, databases are the primary system of record, and organizations are required to keep an accurate picture of all the facts, as they occur. Unfortunately, traditional databases are only temporal and cannot provide a truly accurate picture of your business at different points-in-time.
What organizations need today, particularly in regulated industries, is support for bitemporal data. With a bitemporal database, you can store and query data along two timelines with timestamps for both valid times—when a fact occurred in the real world (“what you knew”), and also system time—when that fact was recorded to the database (“when you knew it”).
