Improved Models of Internet Charging Scheme of Single Bottleneck Link in Multi QoS Networks

Abstract

This paper will seek new proposed pricing plans to develop new pricing scheme that serve both customers and maximize the supplier profit as nowadays Internet Service Providers (ISPs) deal with high demand to promote good quality information but only a few pricing plans involve QoS networks. We are going to solve multi bottleneck links in multi QoS Network scheme as an optimization model by comparing two models in multi QoS networks by taking into consideration decision whether to set up base price to be fixed to recover the cost or to be varied to compete in the market and quality premium to be fixed to enable user to choose classes according to their preferences and budget or to be varied to enable ISP to promote certain service. The results were obtained by aid of LINGO 13.0 software application. The results show that our two modified models slightly yield better solution rather than in original problem but with advantages that ISP has options to choose which of two models to be adopted depending on ISP goals in achieving the profit maximization.
