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.
