Summary:
To distribute contents through Information-centric networks (ICN) was proposed as an important future Internet architecture, in which contents was considered as the main part. In ICN, contents name are the routing locator for efficient contents distribution. Contents are dynamically cached in network routers of Internet service providers (ISPs), which is different from traditional content distribution networks that still use IP address as routing locator. Caching has been identified as a critical component. Many cache mechanisms determine contents' cache time by the popularity of the contents, i.e., popular contents can be kept in cache for much longer time. Instead, our previous work has proposed a time-to-live based caching mechanism for ISPs to monetize their cache resource, in which the contents' cache time is determined by contents provider's (CP's) payment, and the CP was charged by an affine price function of contents cache time in ISPs' cache. In this paper, a concave pricing mechanism is considered, and CP is charged by an concave price function of contents cache time in ISPs' cache. We theoretically analyze the proposed concave pricing mechanism and provide solution for CP to optimally choose the time length stay in ISP's cache.
