| Summary: | 碩士 === 國立交通大學 === 資訊工程研究所 === 82 === A Service Control Point (SCP) is the "Heart" of Intelligent
Network (IN), it acts as a database within a computer network,
and performs IN service call processing function. The main
difference between them is that the SCP service call handling
is time sensitive, and it uses the Transaction Capabilities
Application Part (TCAP) protocol service that provides reliable
transaction associations between SCPs and Service Switching
Points (SSPs). Performance is an important factor that affects
the quality of IN service. The estimation of the SCP
performance and the detail system design requirements are the
most important problem to solved. Message Generator and Traffic
Simulator (MGTS) is often used in the Intelligent Network to
measure the system performance, the essential feature of MGTS
on performance evaluation is to measure the response time of a
signaling point (SP) under various message traffic rate, quite
limited information can be obtained from the measurement. In
this thesis, we propose a generic queuing model, which uses
simulation technique to simulate and observe the behavior of
SCP call processing function under various traffic conditions.
Some important factors, that have to be considered in
designning a reliable and a predicatable SCP system, may be
obtained from the analysis of simulation results. This method
will reduce the time spent for performance evaluation, and
obtain more information related to the requirements of SCP
system detail design.
