The Optical Internetworking Forum (OIF) is concerned, among other things, with the continuity of services in optical networks.
To this end, the OIF has developed a specification for the UNI interface, User Network Interface (UNI), the OIF UNI Signalling 1.0 for signalling. A further step is with Generalized Multiprotocol Label Switching (GMPLS), label switching in optical systems. OIF UNI Signalling allows, among other things, the activation of additional colors in an optical add/drop multiplexer for the purpose of dynamic bandwidth adjustment.
In addition, the OIF Forum has developed the specifications for Infiniband, which was established in 2005 with a Double Data Rate (DDR) of 5 Gbit/s.
