Abstract
Tremendous growth in storage needs for large and medium enterprises, coupled with a need to ensure business continuity, created new service opportunity for carriers: to provide transport of storage protocols such as Fibre Channel and ESCON in Metro, regional and national networks. A key method that is now in development uses GFP mapping of transport storage protocols over SONET/SDH. Current offerings of Fibre Channel transport over SONET/SDH are based on one of the following methods: GFP-T, FC-BB_SONET and FC-BB_GFPT. The paper discusses the main features of each method. The main topics that are analyzed: Rate limit, Performance over long distances, Transparency, Utilization of the SONET/SDH network, A-Z management of a fiber channel service including performance monitoring, fault recovery and network demarcation issues. Finally – The benefits to service providers are outlined.
