| Outline of Research at the Start |
The pricing of network bandwidth and caches plays important roles in monetizing system resources of Internet service providers (ISPs), and thus incentivizes them to provide quality of service (QoS) for users, especially for the future Internet architectures such as information-centric networks (ICN). In this project, we research on 1) practical contract designs under which ISPs can better monetize and manage caches, and 2) the premium peering between ISP and contents provider (CP), under which ISP allocates bandwidth based on CP’s paymen

| Outline of Final Research Achievements |
The pricing of network bandwidth and caches plays important roles in monetizing system resources of Internet service providers (ISPs), and thus incentivizes them to provide quality of service (QoS) for users, especially for the future Internet architectures such as information-centric networks (ICN). The research results of this project are two folds: 1) We have designed practical contract under which ISPs can better monetize and manage caches, and 2) We have developed the premium peering between ISP and CP, under which ISP allocates bandwidth based on CP’s payment. The time-based caching contracts and the corresponding pricing schemes for ICN has been studied, and the premium peering mechanisms between multiple competing ISPs and CPs where ISPs set price have been studied for allocating bandwidth to achieve QoS. Several academic papers have been published.

| Academic Significance and Societal Importance of the Research Achievements |
The findings of this research project offer practical solutions for improving the monetization and management of network resources, while also fostering a more efficient and user-oriented internet service ecosystem. They could also influence both academic research and industry practices.
