OSRP (Optical Signaling & Routing Protocol)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
OSRP is an optical routing protocol similar to PNNI (Private Network-to-Network Interface) and MPLS (Multiprotocol Label Switching), which was developed for ATM networks. Through OSRP, switches can exchange information about the network and the status of switches and links. OSRP works in an environment of switches that handles multiple wavelengths of light as circuits, automatically provisioning entire wavelengths or fractions of wavelengths available on a fast-switched basis. An alternative optical routing protocol is FSPF (Fabric Shortest Path First), which was developed by Brocade.
