Aruba OS8 lands, with APIs so non-NetAdmins can do NetAdmin jobs

First they came for the DBAs. Then they came for the storage admins. Now the software-defined networking (SDN) shock troops are coming for network administrators.

Software-defined networking is dangerously sniffable

Software-defined networking (SDN) controllers respond to network conditions by pushing new flow rules to switches. And that, say Italian researchers, creates an unexpected security problem. The researchers were able to persuade their SDN environment to leak information that sysadmins probably don't want out in public, …

VMware/Cisco software-defined spat thaws as ACI comes to vSphere

When VMware acquired Nicira and released its NSX product, it looked like Virtzilla and Cisco were on a collision course. But now Cisco has added a vCenter plug-in to the new version of its own software-defined networking (SDN) software, one of several signs that the two companies are working together while also competing to …

VMware quietly sneaks out NSX 6.2 update and/or bug-blast

VMware has quietly let NSX 6.2 out the door, so those of you hoping for a big software-defined networking (SDN) announcement at VMworld next week can probably resign yourself to a dull keynote. The biggest change is that you'll need more memory and CPU cycles to get NSX working. VMware says you'll now need at least 16GB of …

Telcos' revenge is coming as SDN brings a way to build smart pipes

Telcos, terrified of being consigned to eternal status as ‘dumb pipes’, keep coming up with crazy ideas for over-the-top (OTT) high-value services.

Juniper gives itself an uppercut, plans white box switch running Junos OS

Analyst calls it: we've got a software-defined networking BUBBLE

Forrester analyst Andre Kindness has used two very significant words - “irrational exuberance” - to describe the white box networking market. “Irrational exuberance” was famously used by former US Federal Reserve chair Alan Greenspan in a 1996 speech bemoaning over-valued assets.
