英文摘要： This project will create new knowledge and understanding on a novel time-varying combination circuit-switching network, with the ultimate goal of addressing the demands of future Internet applications. The intellectual merit of this project lies in the introduction of storage equipment and cross-layer control unit into the traditional circuit-switching networks. This project seeks to solve the problem of resource inefficiency in traditional circuit-switching networks, created by the end-to-end circuit provisioning mechanism, bandwidth over-provisioning, and multi-layer control and management. The time-varying combination circuit-switching network differs from the traditional circuit- and packet- switching networks, because it is leveraged by optimal traffic aggregation and combination of circuits and storage equipment in time dimension. This technique will not only substantially improve network bandwidth efficiency, but also guarantee provisioned bandwidth and quality of service (QoS). This project will study three key problems under time-varying combination circuit-switching networks: (1) architecture, control and management schemes; (2) routing algorithms and resource allocation schemes under time-varying resources; and (3) data-transmission protocols for interruptible circuit connections. Based on the studies proposed above, an experimental testbed will be built to verify the effectiveness of the proposed architecture and schemes in (1), and to evaluate the performance of the algorithms in (2). We seek to have a broader impact for future Internet architecture and novel applications, by creating a set of theoretical knowledge and techniques, and generating supporting experimental data.
