Topic: “How Bandwidth Virtualization Enables a
Services-oriented Optical Network Architecture”
Speaker: Mr Leigh Wade, Global Technical
Director, Infinera
Abstract
Bandwidth Virtualization is the use of digital
technology to decouple the service layer from
the underlying optical transmission
infrastructure, thereby enabling the
implementation of a programmable optical
network. It allows any transport service (e.g.
GbE, 2.5G, 10G, 40G, etc) to be immediately
provisioned to any network location without
regard to optical engineering and without
hardware modification inside the network.
Bandwidth Virtualization enables a common pool
of service-ready optical bandwidth to be used
for mix of service types and service data rates.
Bandwidth Virtualization also enables new
service offerings such as Layer1 Optical VPNs
and true on-demand IP capacity as well as new
carrier business models based on service
activation speed as a competitive
differentiator.
This case study will discuss
the following examples of the service
flexibility enabled by bandwidth virtualization,
and discuss how a leading network operator has
used bandwidth virtualization to gain a strong
advantage in offering differentiated transport
services. (i) Seamless
migration from 10G services to 40G services -
Highlights the business case for introducing 40G
services on a network that is carrying
predominantly 10G services, without any changes
to the optical transmission network.
(ii) Layer 1 Optical VPNs as a new service
offering - L1 Optical VPNs offer the
end-customer control, security, and flexibility
of a customer managed network, while allowing
the service provider customer retention and a
new source of revenue.
(iii) Service ready in less
than 10 days - Bandwidth virtualization enables
a just-in-time service activation model as the
network is pre-engineered with service-ready
bandwidth that is activated by simply inserting
service cards at the end-points.
