“ SDN in WAN: There were three transport focused companies at the conference: CIEN, Cyan and Vello. Ever since the Google OpenFlow WAN presentation at2012 ONS, there has been a lot of interest in how SDN fits in the WAN. The VP of Engineering for Vello commented that transport is complex, resources (i.e. fiber?) are scarce and cited the Google OF WAN. They are focused on DC to DC interconnects. The CTO of Ciena (an old colleague from my CIEN days) commented that the problem SPs have is how to get a lot of capacity to many locations cheaply. He describes this decade as the M2M decade coming off the mobility and internet booms from the prior decades. He also made some other comments that I would agree with: (i) if SPs can separate compute of topology from path calculation that could become very powerful for carriers and (ii) the SDN proposition for the carrier is the ability to have levers that change the underlying wires of the network more than once every 3-7 years. Imagine if they could change them many times a day! That last sentence was a veiled Plexxi comment by me. „
