PROJECT TITLE :
SERvICE: A Software Defined Framework for Integrated Space-Terrestrial Satellite Communication - 2018
The existing satellite communication systems suffer from ancient design, such as slow configuration, inflexible traffic engineering, and coarse-grained Quality of Service (QoS) guarantee. To address these issues, during this Project, we propose SERvICE, a Software dEfined fRamework for Integrated house-tErrestrial satellite Communication, based on Software Defined Network (SDN) and Network Function Virtualization (NFV). We have a tendency to first introduce the 3 planes of SERvICE, Management Plane, Management Plane, and Forwarding Plane. The framework is intended to realize versatile satellite network traffic engineering and fine-grained QoS guarantee. We analyze the agility of the house element of SERvICE. Then, we tend to offer an outline of the implementation of the prototype with the help of the Delay Tolerant Network (DTN) and OpenFlow. We tend to conduct two experiments to validate the feasibility of SERvICE and also the functionality of the prototype. In addition, we propose 2 heuristic algorithms, namely the QoS-oriented Satellite Routing (QSR) algorithm and also the QoS-oriented Bandwidth Allocation (QBA) algorithm, to guarantee the QoS demand of multiple users. The algorithms are evaluated within the prototype. The experimental results show the efficiency of the proposed algorithms in terms of file transmission delay and transmission rate.
