Abstract
A method of and system for managing a SONET ring computes an optimally balanced demand loading for the SONET ring and generates an updated time slot assignment map for each node of the SONET ring based upon the optimally balanced demand loading. The method causes each node of the SONET ring to switch substantially simultaneously to its updated time slot assignment map, thereby reconfiguring the SONET ring.
Claims20
A method of managing a SONET ring, which comprises the steps of:
- (a) computing an optimally balanced demand loading for said SONET ring, wherein each link of said SONET ring carries substantially the same demand as every other link of said SONET ring;
- (b) generating an updated time slot assignment map for each node of said SONET ring based upon said optimally balanced demand loading;
- and,
- (c) causing each node of said SONET ring to switch substantially simultaneously to said updated time slot assignment map generated for said each node.
The method as claimed in 1, including the step of determining if any element of said SONET ring is in protection mode prior to performing step (c).
A system for managing a SONET ring, which comprises:
- means for computing an optimally balanced demand loading for said SONET ring wherein each link of said SONET ring carries substantially the same demand as every other link of said SONET ring;
- means for generating an updated time slot assignment map for each node of said SONET ring based upon said optimally balanced demand loading;
- and,
- means for causing each node of said SONET ring to switch substantially simultaneously to said updated time slot assignment map generated for said each node.
A SONET ring system, which comprises:
- a plurality of nodes interconnected by links in a ring topology, each of said nodes including means for storing an active time slot assignment map and a secondary time slot assignment map, and each of said nodes including means for substituting a secondary time slot assignment map for an active time slot allocation map at a designated time;
- and,
- a ring management system in communication with each node of said SONET ring, said ring management system including:
- means for computing an optimally balanced demand loading for said SONET ring;
- means for generating a secondary time slot assignment map for each node of said SONET ring based upon said optimally balanced demand loading;
- and,
- means for downloading to each node of said SONET ring a secondary time slot assignment map generated for said each node and a designated time for said each node to swap substitute said downloaded secondary time slot assignment map.
