How Bandwidth Virtualization Enables a Services-oriented Optical Network Architecture and Optimizing IP over WDM Core Networks

Time 04/22/08 03:00PM-04:00PM

Session Abstract

Bandwidth Virtualization is the use of digital technology to decouple the service layer from the underlying optical transmission infrastructure. 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 presentation will discuss the following examples of the service flexibility enabled by bandwidth virtualization. (i) Seamless migration from 10G services to 40G services - Highlights a simple evolution path 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) Rapid service provisioning and reconfiguration - 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. /

As bandwidth intensive research and experimental applications proliferate in R&E networks, scaling IP router trunk capacity while optimizing IP and optical transport network architecture is becoming very important. This talk will review key IP over Optical network architecture options that can affect the network operators? ability to cost-effectively scale network capacity. This talk will highlight methods of cost reduction of core IP/Optical networks by optimizing the overall IP and optical network architecture rather than designing independent IP and optical networks. Key topics to be discussed include migration to 40G and 100G router trunks, increasing IP router bypass, implementing reconfigurable digital optical networks (ROADMs), implementing UNI-based IP-optical inter-working using GMPLS and exploring optimal system architectures for integrating packet bandwidth management with reconfigurable multi-wavelength optical transport.
