LAS VEGAS -- Interop -- OK, maybe there wasn't exactly a "frenzy" over software-defined networking (SDN), especially considering the first and last keynotes Wednesday morning neatly avoided the topic. It was a good morning of discussion regarding the future of the network, though, with SDN overshadowing even the non-SDN parts. Some audience members grumbled about the product-heavy nature of keynotes from Cisco Systems Inc. and Juniper Networks Inc., but an SDN panel and a surprise announcement from the Open Compute Project seemed to go over well. And judging by this line, there's still a hunger to sit in a dark room after breakfast and listen to relative strangers talk into microphones. Click forward for more (of the keynotes, not the line).
