  • A research platform for software defined Satellite Networks
    2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017
    Co-Authors: Changjiang Fei, Baokang Zhao, Jinzhen Bao
    Abstract:

    Software Defined Satellite Networking (SDSN) provides an innovative perspective to manage Satellite Network through logically centralized Network view and standard interfaces between the control and data plane. Significant advantages of SDSN include enabling integration of space and terrestrial Network, flexible and efficient resource management, rapid and economical Network function updating, etc. However, at present, there is not an experiment platform specially for SDSN, restricting the in-depth study of SDSN. Therefore, in this paper, we propose OpenSatNet, a platform for software defined Satellite Networking research. OpenSatNet uses lightweight OS-level virtualization, including Network namespaces and virtual Network devices, can emulate a realistic Satellite Network and has a user-friendly graphical user interface (GUI). Through OpenSatNet, researchers can easily conduct a realistic experiment for SDSN on their PCs. The snapshot routing for SDSN is implemented to demonstrate the operation of our platform.

  • opensan a software defined Satellite Network architecture
    ACM Special Interest Group on Data Communication, 2015
    Co-Authors: Jinzhen Bao, Baokang Zhao, Zhenqian Feng, Zhenghu Gong
    Abstract:

    In recent years, with the rapid development of Satellite technology including On Board Processing (OBP) and Inter Satellite Link (ISL), Satellite Network devices such as space IP routers have been experimentally carried in space. However, there are many difficulties to build a future Satellite Network with current terrestrial Internet technologies due to the distinguished space features, such as the severely limited resources, remote hardware/software upgrade in space. In this paper, we propose OpenSAN, a novel architecture of software-defined Satellite Network. By decoupling the data plane and control plane, OpenSAN provides Satellite Network with high efficiency, fine-grained control, as well as flexibility to support future advanced Network technology. Moreover, we also discuss some practical challenges in the deployment of OpenSAN.

  • Networking in Space Terrestrial Integrated Networks
    2019 18th International Conference on Optical Communications and Networks (ICOCN), 2019
    Co-Authors: Baokang Zhao, Changjiang Fei, Xilong Mao, Wanrong Yu, Chunqing Wu
    Abstract:

    The space terrestrial integrated Network connects the Internet, mobile communication Network and other terrestrial Networks through a space-based Network, which is an important way to achieve global Network coverage. However, different technologies, standards, and protocols make it difficult to interconnect space-based Networks and terrestrial Networks. Therefore, in this paper, we propose IPSN, an IP-based hierarchical Space terrestrial integrated Network architecture. In IPSN, the space-based Network is divided into three levels: intra-Satellite Network, inter-Satellite Network and Satellite-ground Network, each of which uses the mature IP protocol of terrestrial Network. We also designed space routers and launched them into space, conducted Networking experiments in space. IPSN can effectively integrate space-based Networks with terrestrial Networks and promote the application of mature and state-of-the-art technologies in terrestrial Networks to space-based Networks.

  • Virtual Strategy QoS routing in Satellite Networks
    Science in China Series F: Information Sciences, 2016
    Co-Authors: Heyu Liu, Fu-chun Sun, Shaoqing Wang
    Abstract:

    Satellite Network users want to unify different Satellites to enhance the quality-of-service (QoS) stability of the Satellite Networks and select feasible paths through different Networks to feed different applications. Unfortunately, the state of affairs is that different applications need to use several different application programming interfaces and to design different protocols on how and when to use a specific Network. This is troublesome and error-prone as the application programming interfaces vary a lot. In this paper, we design a Virtual Strategy in Satellite Network based on which a QoS routing service scheme is then proposed. We analyze why applications should use and benefit from Virtual Strategy. This Virtual Strategy is a middleware solution that enables seamless usage of services from different Satellite Network parts. And then, the supporting QoS routing solution enables the committed QoS services over Virtual Strategy. Finally, we provide a comparison between the previous Satellite Networks and our work. The simulation results show that our Virtual Strategy QoS routing scheme demonstrates dominated performances under complex architecture.

  • A QoS-Oriented Congestion Control Mechanism for Satellite Networks
    Mathematical Problems in Engineering, 2014
    Co-Authors: Heyu Liu, Fu-chun Sun
    Abstract:

    The sharply increasing amount of data, which are transferred by the Satellite Network, requires the Satellite Network to provide quality-of-service (QoS). However, the upsurge in the data flow leads to the Network congestion, impeding its ability to offer QoS. Congestion control mechanisms, deployed in the ground Networks, have been thoroughly studied. But those deployed in the Satellite Networks have not been studied yet. As Satellite Networks are now important supplements to the ground backbone Networks, this paper carefully analyzes the current challenges of developing the QoS-oriented congestion control mechanism for Satellite Networks. On this basis, a consequent mechanism QMCC (QoS-oriented mechanism of congestion control for Satellite Networks) is described in detail. Under that QMCC, the source nodes utilize an equation to compute the sending rate for each data flow; meanwhile, the intermediate nodes keep detecting real-time package-loss rates for timely adjustments. Simulation results indicate QMCC can provide superior congestion control performance, and raise Network throughputs without reducing the QoS effects.

  • A Novel Routing Algorithm Based on Multi-Objective Optimization for Satellite Networks
    Journal of Networks, 2011
    Co-Authors: Fei Long, Fu-chun Sun, Zhian Yang
    Abstract:

    Routing algorithm plays a critical role in determining the performance and reliability of a Satellite Network. Since the resources in Satellite Networks are constrained, it is a big c hallenge to find paths that satisfy all QoS requirements in a low cost for Satellite Network users. In this paper, a novel routing scheme together with two multi objective optimization routing algorithms-prior order algorithm and beehive algorithm are proposed to solve this problem in hierarchical Satellite Networks. Simulation results show that the proposed routing method can achieve efficient optimized in all preset QoS parameters and performs well in hierarchical Satellite Network.

    Co-Authors: Fei Long, Fu-chun Sun, Zhian Yang
    Abstract:

    Routing scheme plays a critical role in determining the performance and reliability of a Satellite Network. Since the resources in Satellite Networks are constrained, a major challenge in Satellite Network routing is how to find paths that satisfy all user QoS requirements in a low cost. In this paper, a multi-QoS optimization routing scheme is proposed to solve this problem in hierarchical Satellite Networks. Simulation results show that this scheme can achieve efficient routing optimized in all preset QoS parameters and performs well in hierarchical Satellite Network.

  • Benchmarkinng of Routing Protocols for Layered Satellite Networks
    The Proceedings of the Multiconference on "Computational Engineering in Systems Applications", 2006
    Co-Authors: Junfeng Wang, Fu-chun Sun
    Abstract:

    As a key part of Next Generation Network (NGN) infrastructure, next generation broadband Satellite Networks are expected to support a variety of applications with diverse performance requirements. Research on the onboard routing protocols is the primary step to meet the various QoS related requirements, which becomes feasible with the rapid development of onboard processing capacity of Satellite. In the paper, we evaluate the more fundamental metric of convergence rate of RIP, OSPF, DRDT and MLSR routing protocols under various Satellite Network scenarioes based on simulation. Though many literatures have argued that the routing protocols running in terrestrial Networks do not fit well for Satellite Networks, this paper presents the simulation-based evaluation of typical terrestrial routing protocols in Satellite settings quantitatively and serves as a benchmark for Satellite Network routing protocol development and performance evaluation.
