So What Exactly Is SDN?

Five years after the SDN hype exploded, it remains as meaningless as Cloud, and it seems that all we’re left with is a plethora of vendors engaged in SDN-washing their products.

Even when a group of highly intelligent engineers considering these topics on a daily basis gets together they don’t get very far apart from a great question: “what business problem is it supposed to solve?” (or maybe they got distracted by irrelevant hot-air opinions).

Is it still worth trying to find a useful definition of SDN? It seems it’s easier to list what SDN is not like I’ll be doing in the free Introduction to SDN webinar on February 10th. Let’s see:

Protecting IP or Market Share?

Protecting IP or Market Share?

It's tough times on Tasman Drive.  Struggling to apply old technology to the new world of cloud computing, Cisco is potentially facing the largest loss of data center market share in its history.  We can understand why Cisco would take the battle from the marketplace to the courtroom.  What surprises us is the length that Cisco has gone to misrepresent our actions and the nature of the litigation in order to justify their assault.

Q&A: As prices fall, flash memory is eating the world

Western Digital in October announced plans to acquire SanDisk for some $19 billion in a deal that -- once finalized -- will marry leaders in the traditional hard drive and the emerging flash memory markets. Sumit Sadana, SanDisk's chief strategy officer and general manager of its Enterprise Solutions unit, spoke recently with IDG Chief Content Officer John Gallant to share insights on the merger and to explore the evolving role of flash in corporate data centers. What continues to hold enterprise back with flash? Just the price perception issue?Is the cloud a threat to your consumer device business? More and more, consumers use the cloud for photos or other things that they're saving. Is it such that the better the cloud opportunities get, the weaker the consumer opportunity gets?To read this article in full or to leave a comment, please click here(Insider Story)

IDG Contributor Network: Next frontier: Aquatic IoT

Underwater communications networks are excruciatingly slow, and that's hampering oil and gas exploration and scuba communications, among other businesses.The communications technology needs upgrading to more closely match high-speed, through-air radio networks, say experts.One answer may be to adapt software-defined radios and couple them with special underwater acoustic modems, according to electrical engineers at the University of Buffalo.Radio too slow Sound-waves—like those used by whales and dolphins—as opposed to radio-waves, are the best media for communicating underwater, the scientists say.Traditional radio methods don't work properly. The problem is that radio doesn't function well underwater. Commercial underwater modems are slow, and voice solutions are limited by distance and clarity, the scientists say.To read this article in full or to leave a comment, please click here

Worth Reading: Disaggregation at LinkedIn

Disaggregation has been on the top of my mind a good bit recently, partially because of our work at LinkedIn around this topic. Zaid has just posted a piece on the LinkedIn Engineering Blog about Project Falco, which is our internal disaggregation project for our data centers. Just a little taste to convince you to jump over there and read this one, because I think this sort of thing will have a major impact in the networking industry over the next three to five years.

Pigeon is a 3.2Tbps switching platform that can be used as a leaf or spine switch. Pigeon is our first foray into active switch software development. We are not venturing into developing our own switch because we aspire to become experts in the switching and routing space, but because we want control of our destiny. We continue to be supportive of our commercial vendors and work with them in a decoupling model.

Comcast targets first markets it will offer gigabit over copper cable service

Comcast announced today that Atlanta and Nashville would be its first two markets to offer DOCSIS 3.1 technology, in “early 2016,” and that Chicago, Detroit and Miami would join them in the second half of the year.DOCSIS 3.1 is a new wired cable Internet standard, which gives Comcast the ability to offer gigabit speeds over existing copper cable. The latest version of the standard uses smaller subcarrier channels that use considerably less bandwidth than those of DOCSIS 3.0, bonding those subchannels together for greater efficiency. The company said that it tested the technology last month in its home market of Philadelphia.+ALSO ON NETWORK WORLD: 'Big bets' cost Google parent Alphabet $3.6 billion in losses last year + Microsoft starts recommended update roll-out for Windows 10To read this article in full or to leave a comment, please click here
