[It is exciting to see that the concept of "virtualization" and
"Infrastructure as a Service (IaaS)" is starting to take hold in the
telecommunications world.  Virtualization of computers and networks will
also go a long way to addressing the challenges of CO2 emissions by the ICT
industry.  Companies like Inocybe (www.inocbye.ca) have also extended and
generalized the concept of network virtualization to all types of networks
and services. Excerpts from www.convergedigest.com--BSA]

Infinera Offers Bandwidth Virtualization over Optical Transport Infinera is
promoting the concept of "Bandwidth Virtualization" over optical transport
networks based on its digital circuit technology as a means to meet the
needs for a faster, more responsive Internet.

In a traditional optical network using Wavelength Division Multiplexing
(WDM), each service that a service provider sells is typically linked to a
specific wavelength, which is installed and turned up after a customer
commits to purchase that service. Each service to be sold typically requires
pre-planning, engineering activities and testing at time of installation,
and there is often a significant delay between customer commitment to
purchase and turn-up of the corresponding service. Service providers
introducing new services, such as 40 Gbps and 100 Gbps services, must
frequently re-engineer or overbuild their WDM networks to support the new
services, creating long cycles between end-user service requests and service
delivery, as well as inefficient network utilization, operational
complexity, and the need for additional capital outlays.

Infinera said Bandwidth Virtualization overcomes these challenges and
accelerates operators' speed of service provisioning by decoupling the
service layer in the network from the underlying optical transmission layer.

Bandwidth Virtualization is enabled by an Infinera Digital Optical Network
using high-capacity photonic integrated circuit technology on every route in
the optical network, and integrates sub-wavelength digital switching with
end-to-end software intelligence. This provides operators with a readily
available pool of WDM bandwidth to meet immediate service requests, and
allows new services to be deployed over the same infrastructure. The
transmission layer can be configured to support any service simply by
installing a service interface module at each of the two service endpoints
and activating new end-to-end services using software rather than via
hardware-based re-engineering of network resources.

Bandwidth Virtualization also yields significant operational benefits for
service providers. By deploying hundreds of Gigabits of capacity at initial
installation and being able to turn up additional services with digital
plug-and-play ease, service providers can operate their network with smaller
skilled engineering teams and at lower cost than on traditional WDM
networks.
