    ABSTRACT: We discuss the generic framing procedure (GFP) in the context of emerging nontraditional data over transport applications. Coupled with complementary efforts to define virtual concatenation, automatic link capacity adjustment schemes, and distributed control planes for transport networks, we contend that GFP serves as the catalyst for efficient and standard data over transport service offerings

    ABSTRACT: This article describes the 2005 Worldwide Interoperability Demonstration held by the Optical Internetworking Forum and showcased during SUPERCOMM 2005, The event highlighted Ethernet services transported over intelligent optical networks, using equipment from 13 of the industry's leading vendors located in seven carrier laboratory facilities around the world. The demonstration utilized a distributed optical control plane based on OIF Implementation Agreements to control a multilayer network providing Ethernet over SONET/SDH adaptation and transport. The article describes the global test network, services, architecture, and overall test approach. It also describes innovations made to the optical control plane to handle multilayer signaling and lists further refinements needed to make these services operational.

    ABSTRACT: This paper addresses the issue of reliable transport of emerging data services in Ethernet over SONET (EoS) networks that require protection guarantees beyond standard best effort delivery. We argue that the current consensus of using Ethernet spanning tree and a SONET 1+1 protection, while providing reliability, is an inefficient use of resources. Instead, we claim that EoS opens novel opportunities for protection heretofore unavailable in other environments. In particular, the deployment of virtual concatenation and LCAS protocols enables "route splitting", creating a fundamentally new routing paradigm for circuit-switched environments. We propose a scheme called PESO, appropriate for EoS, with innovative routing, failure notification and switching components. More importantly, it is competitive with SONET protection without its 100% bandwidth overhead. We also suggest a enhancement in LCAS that can further improve PESO'S switching time. PESO leverages the underlying protocols, making it extremely attractive to implement and use in practice.
