Path Routing in Mesh Optical Networks (PDF)

Transport networks evolved from DCS (Digital Cross-connect
Systems)-based mesh architectures, to SONET/SDH (Synchronous
Optical Networking/Synchronous Digital Hierarchy) ring
architectures in the 1990's. In the past few years,
technological advancements in optical transport switches have
allowed service providers to support the same fast recovery in mesh
networks previously available in ring networks while achieving
better capacity efficiency and resulting in lower capital cost.

Optical transport networks today not only provide trunking
capacity to higher-layer networks, such as inter-router
connectivity in an IP-centric infrastructure, but also support
efficient routing and fast failure recovery of high-bandwidth
services. This is possible due to the emergence of optical network
elements that have the intelligence required to efficiently control
the network. Optical mesh networks will enable a variety of dynamic
services such as bandwidth-on-demand, Just-In-Time bandwidth,
bandwidth scheduling, bandwidth brokering, and optical virtual
private networks that open up new opportunities for service
providers and their customers alike.

Path Routing in Mesh Optical Networks combines both
theoretical as well as practical aspects of routing and
dimensioning for mesh optical networks. All authors have worked as
technical leaders for the equipment vendor Tellium who implemented
such capabilities in its product, and whose product was deployed in
service provider networks.

Path Routing in Mesh Optical Networks

* Presents an in-depth treatment of a specific class of optical
networks, i.e. path-oriented mesh optical networks.

* Focuses on routing and recovery, dimensioning, performance
analysis and availability in mesh optical networks.

* Explains and analyses routing specifically associated with
Dedicated Backup Path Protection (DBPP) and Shared Backup Path
Protection (SBPP) recovery architectures.

As most of the core backbone networks evolve to mesh topologies
utilizing intelligent network elements for provisioning and
recovery of services, Path Routing in Mesh Optical Networks
will be an invaluable tool for both researchers and engineers
in the industry who are responsible for designing, developing,
deploying and maintaining mesh optical networks. It will also be a
useful reference book for graduate students and university
professors who are interested in optical networks or
telecommunications networking.
