Tidbits: Oracle-Arista Rumor, Controller Complexity, More Cisco SDN

This Week’s Rumor

Rumors that Oracle is considering an acquisition of Arista Networks have circulated this week. They’re likely nothing more than idle chatter. Arista has rejected takeover overtures previously, and it seems determined to go the IPO route.

Controller Complexity

Lori MacVittie provides consistently excellent blogging at F5 Networks’ DevCentral. In a post earlier this week, she examined the challenges and opportunities facing OpenFlow-based SDN controllers. Commenting on the code complexity of controllers, she writes the following:

This likely means unless there are some guarantees regarding the quality and thoroughness of testing (and thus reliability) of OpenFlow controllers, network operators are likely to put up a fight at the suggestion said controllers be put into the network. Which may mean that the actual use of OpenFlow will be limited to an ecosystem of partners offering “certified” (aka guaranteed by the vendor) controllers.

It’s a thought-provoking read, raising valid questions, especially in the context of enterprise customers.

Cisco SDN

Last week, Cisco and Morgan Stanley hosted a conference call on Cisco’s SDN strategy. (To the best of my knowledge, Morgan Stanley doesn’t have one — yet.)  Cisco was represented on the call by David Ward, VP and chief architect of the company’s Service Provider Division; and by Shashi Kiran, senior director of market management for Data Center/Virtualization and Enterprise Switching Group.

The presentation is available online. It doesn’t contain any startling revelations, and it functions partly as a teaser for forthcoming product announcements at CiscoLive in San Diego. Still, it’s worth a perusal for those of you seeking clues on where Cisco is going with its SDN plans. If you do check it out, you’ll notice on side three that a number of headlines are featured attesting to the industry buzz surrounding SDN.  Two bloggers are cited in that slide: Greg Ferro (EtherealMind) and, yes, yours truly, who gets cited for a recent interpretation of Cisco’s SDN maneuverings.
