Method to protect RPR networks of extended topology, in particular RPR ring-to-ring and meshed backbone networks, and relating RPR network |
摘要 |
A method for protecting RPR networks of extended topology, in particular RPR Ring-to-Ring and Meshed Backbone networks having a number of RPR rings interconnected according to one or more hierarchical tree structures, in which the protection is carried out at two levels: Intra-Ring Protection, reacting to failures on a single RPR ring; Inter-Ring Protection, reacting to failures that occur between two different RPR rings by using at least two RPR Gateways at the interface between two RPR rings.
