What IS a wave (if you’re a carrier)?
• Looks a lot like a circuit:
– QWave™ is an economical private line service option for
customers who want greater control and visibility of their
broadband services. This service is an optical wavelength
product offering that utilizes Dense Wave Division
Multiplexing (DWDM) technology. QWave is available in
capacity bandwidths of Optical Carrier (OC)-48 and OC-192.
It is a linear routed, unprotected, point-to-point, non-switched
transport service.
• Specific bit-rate
• Typically longer term that traditional circuits
What could a wave be?
• We want
– an allocation of spectrum within the fiber
– to be able to modify the bit-rate for
minimum cost
– To be able to change protocol
Given a ‘wave’ what are people
using them for?
• Building traditional IP networks
• Bypass or overlays of traditional IP networks
– E-science application specific topologies (static
now -> dynamic?)
– Disaster recovery
• Data center replication
• Offloading of storage
