A metric-based approach for quality evaluation in distributed networking systems

The distributed networking system is a dominant paradigm in the industry. In today’s network industry, security and Quality of service (QoS) are two key services. The distributed network deals with an entire range of parameters coming from different applications. Therefore, it is of great significance to determine a set of key parameters and draw meaningful evaluation outcomes. On the other hand, security mechanisms provide user identification, authentication, consistency and information protection over the distributed environment. This research presents some analyses which draw connections between QoS and security of distributed networks. Then, a metric-based quantifying methodology is presented which quantifies network quality using QoS and security metrics. The QoS quantifying method is then further elaborated. The efficiency of this method is investigated using a range of simulation studies. The simulation analysis and results indicate that the proposed approach facilitates better QoS management and monitoring of the distributed networking systems.
