Research On The Application Adaptability Evaluation Methods Of Internet Architecture

With the increasing complexity of environment, category, and composition of ap-plications on the Internet, it has become a consensus among academia and industry todevelop the next generation of Internet architecture to meet the diverse application needs.However, there is no systematic research evaluating the application adaptation capabilityof proposed architectures in current literature. Most of existing evaluation focused on thefunctionality and performance of the Internet architecture but lack of evaluation frame-works and models that accommodates the change of application. This is partly due tothe complexity of the Internet architecture. We fill the gap in the literature by (a) ana-lyzing the scalability, deployability, and economic demands of the Internet architecturein supporting application services,(b) proposing the concept of the Internet architectureapplication adaptability and its evaluation methods, and (c) studying the development ofthe Internet architecture with the changing of applications. Our main reserach works andconclusions are as follows:1. We provide a comprehensive review of existing research on the developmentof Internet architecture and its evaluation. We analyze the development trends of theInternet applications and their impact on future Internet data distribution architectures.We also review the related works and challenges for the Internet architecture evaluationresearch from the perspectives of models, mechanisms, and methods. Such review helpsus identify the direction for further study.2. We propose the concept of Internet architecture application adaptability and de-sign an evaluation framework according to the challenges and opportunities brought bythe application changes. This framework is based on the service scalability and economicadaptation of the architecture. It reflects the impact of technical and economic factorson Internet architecture application adaptability, measured by the utility and multidisci-plinary. It provides a theoretical basis to build the architecture application adaptabilityevaluation models from multiple perspectives.3. We propose an Internet architecture application adaptability evaluation modelbased on service capacity. This model can evaluate the application adaptability of theInternet architecture under different compositions of and types of applications. We apply this evaluation model to various types of content distribution mechanisms. Our resultsprovide valuable insights to ISPs.4. We propose a tri-network convergence evaluation model based on user utilitytheory. This model takes into consideration of both supply-side factors and demand-side factors including initial network market share, application composition, investment,economic cost and social relationships. It can be used to analyze the development trendsof architectures under the cooperation and competition among ISPs. The findings of thetri-network convergence evolution based on the model and differential equations provideguidance for ISPs’ decision.5. We design a utility-maximizing adaptive in-network caching system. This systemis based on the status quo of application demands and the existing content distributionmechanisms. It employs the multicast and in-network caching in the edge ASes afterconsidering the utility factors such as the cache placement, the data access hotspots, thedata size and the economic cost. This system achieves efficient data distribution undercertain economic cost.
