100%.

New boxes from Juniper that have shipped with a minimum of 10Gbps when 
we still have 1Gbps use-cases has meant we've put orders off. 12 months 
later, they have new iterations of the boxes now allowing for all the 
way down to 1Gbps.

CloudyWorld is giving OEM's the impression that NetworkWorld also have 
the same requirements. It's good to see some OEM's are getting back to 
their roots, but it's not easy work.

DWDM vendors are the worst, because they look at all orders with DCI eye 
glasses.

Mark.
