Communication reliability of network management system under the environment of software bus
Zhen Guo Wu, Luoming Meng · China-Ireland International Conference on Information and Communications Technologies (CIICT 2007) · 2007
A new method for analyzing communication reliability of network management system(NMS) under the environment of software bus is proposed to resolve the problem existed in the current NMS reliability evaluation. Firstly, message transmission process under software bus is summarized from the viewpoints of environment factors and queue behavior; secondly, this process is modeled using time based Petri nets; Finally, the model is analyzed by reduction technologies and matrix geometric method. Some important reliability indices, such as success probability of message transmission, is concluded by applying the models. Numerical examples show that communication reliability of NMS using software bus depend on both environment factors and service capability of queue. This model can be applied to search for bottleneck of communication reliability, which is favor of improving reliability design of NMS.
