The architecture, applications, and experimental verification of a simple neighbor discovery method are presented. The method follows the recent International Telecommunication Union—Telecommunication Standardization Sector (ITU-T) and Internet Engineering Task Force (IETF) standardization, automatically switched optical network (ASON)/generalized multiprotocol label switching (GMPLS), on automatically switched optical networks. The method needs no specific hardware components but claims to be so simple that virtually any equipment with common optical ports can support it. It eliminates the need for costly and complex synchronous optical network/synchronous digital hierarchy/optical transport network (SONET/SDH/OTN) overhead read–write functionality in optical elements such as optical cross connects (OXCs). The method thus offers a fast track to automated optical networks.
