This thesis is to develop an accounting system architecture
based upon the multilayer responsibility model of TMN. The
design of this system meets the TMN requirements, such as
flexibility, reusability, and scalability. So, the proposed
architecture can be used as a platform for developing an
integrated accounting management system. This thesis also
suggests a data collection algorithm to solve the real-time
requirement of future accounting systems. The X.400 message
handling system（MHS） service accounting system is developed
to show the feasibility of the proposed accounting system
architecture.
