Abstract
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.
