Abstract
This paper focuses on the definition and allocation of management information for ATM broadband networks that adopt the virtual path protection mechanism. The definition of management information is proposed to represent, in accordance with international standards, a virtual path with the protection mechanism. To achieve accurate representation, the proposed method features the two distinct managed object classes derived from the "trail" concept, which has been specified in ITU-T recommendations. The allocation of management information is optimized by using computer simulations. The criterion for the optimization is the rapidity of tracking the change-over/back and setting up a virtual path. The system that exchanges messages and updates management information is modeled as a queueing system to evaluate the rapidity. Several alternative allocation methods are compared, and the best method is determined.
