Path Routing in Mesh Optical Networks (Hardcover)
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. With a foreword by Professor
Wayne D. Grover, author of the book Mesh-Based Survivable Networks.
