研究開始時の研究の概要 |
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
|
研究実績の概要 |
We have studied the Interdependency between ISP’s pricing for cache and bandwidth: Because CPs can choose to cache contents and/or use premium peering, their utilities depend on the ISP’s prices of cache and bandwidth. Therefore, How CPs choose the provided services by ISPs under different cache and bandwidth prices, and to understand the impact of the prices on CPs’ utilities is important. And we have some research results on premium peering between multiple ISPs and CPs.

理由
In the proccess of our proposed reseearch, we found that the Interdependency between ISP’s pricing for cache and bandwidth is much more tricky, and we have some new ideas to deal with it, which is out of the initial research plan. In order to get the new research result, we need more time. Furthermore, the research process has also been affected by COVID-19, and the research fee for travelling is not used up for research presentation.

今後の研究の推進方策 |
In this year, we will design and implement a testbed and to evaluate the cache and premium peering mechanisms on the testbed. Some research results will be summarized to publish on international journals and international conferences.
