A Method to Increase Services Availability on Web-based Inter-Enterprise Service Delivery Platforms

摘要

With wide deployment of distributed interenterprise Service Delivery Platforms (SDPs) by the majority of enterprises, there is an urgent need to understand and solve service traffic issues of this evolving architectures. Thus, this paper discusses a mathematical model for the performance analysis of services availability at the inter-enterprise SDPs. The SDP is presented as an analytical model with the total number of customers fixed, thus forming a closed queuing network. The SDP’ distributed architecture is modeled as a finite source queuing model. The expected response time for that model is analyzed and computed. The numerical results and the corresponding curves are provided. And, related to open questions, future work is summarized.
