The WSON RWA information model in this document is grouped into four The WSON RWA information model in this document comprises four
categories regardless of whether they stem from a switching categories of information. The categories are independent of whether

a line subsystem refers to devices such as WDM or Optical Amplifier: ROADM or Optical Add/Drop Multiplexer (OADM), and a line subsystem
refers to devices such as WDM or Optical Amplifier. The categories
are these:
