SONET-based Metro Area Networks

* Shows how to achieve new-generation features with enhanced SONET and other optical architectures
* Compares SONET's features and services with rival Ethernet-based offerings
* Offers design approaches and business models for real-world deployments
* Covers GMPLS generalized MPLS), a red-hot switching technology for wavelength services

In 2001 the telecom industry spent money on solving the Metro Area bandwidth bottleneck. SONET appeals to the telcos because it is widely deployed, reliable, robust, and scalable. But it will need multiple changes and enhancements to compete against the emerging rivil--Ethernet.
