Abstract
A method of managing a telecommunication subnetwork system composed of a number of network elements coupled together through an optical medium to form a Synchronous Optical NETwork (SONET) ring. Each of the network elements receives upon initiation or reconfiguration and then stores an identical ring table or knowledge database that is composed of data in a predetermined format and structure. The ring table defines the ring type and ring identification, number of nodes, ring status, node identification, sequence, and status, and provides ring provisioning tables and embedded SONET ring path identification/status information. The ring table is utilized in each of the network elements for provisioning and other management type functions common within a SONET ring environment.
