Inclusion of Technology-Specific Parameters

The previous sections discussed the enhancements to signaling that allow GMPLS to control the different types of packet and nonpacket networks. GMPLS also allows the inclusion of technology-specific parameters that are carried in the signaling protocol in traffic parameter–specific objects. This section looks at how this applies to SONET/SDH. A description of parameters that are specific to optical transport network (OTN) technology is not included in this book.

The SONET/SDH traffic parameters specify a set for SONET (ANSI T1.105) and a set for SDH (ITU-T G.707), such as concatenation and transparency. Other capabilities can be defined and standardized as well. These traffic parameters must be used ...
