Title : Architectural Framework for Automatic Protection
Provisioning In Dynamic Optical Rings

Given the large installed base of ring fiber-plants and the extensive
experience operators have gained in operating SONET (SDH) ring networks,
optical rings are becoming increasingly important. As such, optical
rings will play a crucial role in the migration from existing TDM-based
SONET (SDH) architectures to more dynamic lightpath provisioning
paradigms. To date, various optical ring concepts have been tabled,
proposing multi-services support and mirroring the fast protection
switching capabilities of existing SONET (SDH) rings. Nevertheless,
the emerging IP-based MPL(ambda)S framework for optical networks is
largely based upon (optical) mesh routing concepts.

how to manipulate these messages.
