A PERFORMANCE MANAGEMENT MODEL AND IMPLEMENTATION USED FOR NETWORK MANAGEMENT
Mu Li · Chinese Journal of Computers · 1999
High speed telecommunication network's (e.g. asynchronous transfer mode) technology promises a flexible, multiservice network that will support the broadband future. It will need to be robust and efficient in delivering quality of service, which will not be achieved by network protocols alone. A network performance management will be needed. If future networks are to be flexible allowing new services to be added easily, then their management systems will need to be equally flexible. Approaches derived from the developing technologies of distributed object oriented computing (common object request broker architecture, CORBA), transportable computation, virtual machine and proactive network management technology could allow management systems to be implemented as sets of small grain, cooperating distributed objects. Such systems should be more flexible, more robust, and easier to modify. On the other side, in order to provide efficient resource utilization and QoS guarantee in high speed networks, the performance and dependability analysis model used for performance management with three primary goals is proposed in this paper. First, use Stochastic Reward Models (SRM) to evaluate combined performance and dependability of network. Second, compute and forecast real timely end to end performance reliability (e.g. PR s0 (t) ), performance availability(e.g. PA s0 (t) ), mean time to failure (MTTF) and dependability(e.g. DT s [T] ) for the overall network. Third, due to the arising complexity of exact SRMs, a complexity reduction approach is given. For highly reliable network's management, an approximation of model, its numerical approach and implementation are also presented in this paper.
