    • 摘要: Software-Defined Networking(SDN)enables flexibility in developing security tools that can effectively and efficiently analyze and detect malicious network traffic for detecting intrusions.Recently Machine Learning(ML)techniques have attracted lots of attention from researchers and industry for developing intrusion detection systems(IDSs)considering logically centralized control and global view of the network provided by SDN.Many IDSs have developed using advances in machine learning and deep learning.This study presents a comprehensive review of recent work ofML-based IDS in context to SDN.It presents a comprehensive study of the existing review papers in the field.It is followed by introducing intrusion detection,ML techniques and their types.Specifically,we present a systematic study of recent works,discuss ongoing research challenges for effective implementation of ML-based intrusion detection in SDN,and promising future works in this field.

    • 摘要: 在软件定义网络(SDN)中,各类网络应用的独立开发以及多用户的网络管理可能导致下发至交换设备的流规则发生冲突,而控制平面与转发平面的分离使得交换设备缺乏策略分析能力,无法独立检测内部的流规则冲突。针对这一问题,提出一种流规则冲突检测系统和检测算法。首先,通过监听、捕获控制平面与转发平面之间的OpenFlow报文,获取即将下发的流规则的信息。然后,使用冲突检测算法判定流规则的冲突类型。该算法根据流规则的匹配协议选择对应的规则集合,从而缩小了检测规模;而且在检测时优先对无冲突(NC)规则的特征进行检测,使得对NC规则的检测效率要高于其他类型的冲突规则。最后,根据冲突类型对流规则进行冲突消解。实验结果表明,所提冲突检测算法的检测准确率可以达到100%,与动态冲突检测模型相比该算法在同等规模的规则集合下的检测时间缩短约47%。且检测时间随NC规则占比的提高而缩短。

    • 摘要: 未来的网络对泛在访问性、高带宽和自治管理都提出了更高的要求。传统的基于手工配置和管理网络设备的方法既笨拙又容易出错,并且难以充分利用网络基础设施的物理资源和服务能力。针对上述问题,业界提出了一种崭新的富有前途的未来网络管理模式——软件定义网络(SDN)。SDN不仅可以解耦控制平面和数据平面,而且具有强大的网络可编程性,从而提供了更高效的网络配置、更好的网络服务和更灵活的网络管理能力。首先,概述SDN的提出背景和相关研究工作;然后,介绍了SDN的基本概念、特点优势及面临的挑战。接下来,针对SDN典型参考模型,对其网络架构进行了说明;最后,探讨了SDN可能实现和应用的方式。

    • 摘要: Time and space complexity is themost critical problemof the current routing optimization algorithms for Software Defined Networking(SDN).To overcome this complexity,researchers use meta-heuristic techniques inside the routing optimization algorithms in the OpenFlow(OF)based large scale SDNs.This paper proposes a hybrid meta-heuristic algorithm to optimize the dynamic routing problem for the large scale SDNs.Due to the dynamic nature of SDNs,the proposed algorithm uses amutation operator to overcome the memory-based problem of the ant colony algorithm.Besides,it uses the box-covering method and the k-means clustering method to divide the SDN network to overcome the problemof time and space complexity.The results of the proposed algorithm compared with the results of other similar algorithms and it shows that the proposed algorithm can handle the dynamic network changing,reduce the network congestion,the delay and running times and the packet loss rates.

    • 摘要: Although the Software-Defined Network(SDN)is a well-controlled and efficient network but the complexity of open flow switches in SDN causes multiple issues.Many solutions have been proposed so far for the prevention of errors and mistakes in it but yet,there is still no smooth transmission of pockets from source to destination specifically when irregular movements follow the destination host in SDN,the errors include packet loss,data compromise etc.The accuracy of packets received at their desired destination is possible if networks for pockets and hosts are monitored instead of analysis of network snapshot statistically for the state,as these approaches with open flow switches,discover bugs after their occurrence.This article proposes a design to achieve the said objective by defining the Intelligent Transmission Control Layer(ITCL)layer.It monitors all the connections of end hosts at their specific locations and performs necessary settlements when the connection state changes for one or multiple hosts.The layer informs the controller regarding any state change at one period and controller collects information of end nodes reported via ITCL.Then,updates flow tables accordingly to accommodate a location-change scenario with a routechange policy.ICTL is organized on prototype-based implementation using the popular POX platform.In this paper,it has been discovered that ITCL produces efficient performance in the trafficking of packets and controlling different states of SDN for errors and packet loss.

    • 摘要: In this paper,we developed a new customizable low energy Software Defined Networking(SDN)based Internet of Things(IoT)platform that can be reconfigured according to the requirements of the target IoT applications.Technically,the platform consists of a set of low cost and energy efficient single-board computers,which are interconnected within a network with the software defined configuration.The proposed SDN switch is deployed on Raspberry Pi 3 board usingOpen vSwitch(OvS)software,while theFloodlight controller is deployed on the Orange Pi Prime board.We firstly presented and implemented the method formeasuring a delay introduced by each component of the IoT infrastructure,ranging from the sensor,the core of SDN,the IoT broker,to an IoT subscriber.Thus,we presented the approach for estimating energy efficiency for SDN based IoT platform proportional to the traffic.The experiments carried out on a real SDN topology based on single-board computers show that our approach not only saves up to 53.56%of energy at low traffic intensity,but also provides QoS guarantee for IoT applications.

    • 摘要: 软件定义网络(software-defined networking,SDN)实现了控制层和转发层设备的分离,但控制转发的解耦使得SDN网络中不同层次设备面临新型的DDoS攻击风险.为了解决上述问题,本文提出了一种SDN环境下基于改进D-S理论的DDoS攻击检测方法,用于检测以SDN控制器和交换机为目标的DDoS攻击.在改进的算法中,本文使用离散因子和纯度因子衡量D-S证据源之间的冲突.同时,结合纯度因子和离散因子调整D-S证据理论的证据源,调整后的证据源将通过Dempster规则融合得到DDoS攻击检测结果.实验结果表明本文提出的方法具有较高的精度.

    • 摘要: 随着互联网的快速发展,信息安全问题备受关注,相关研究人员一直致力于研究加密方案,单靠计算进行加密的方法已经不再安全。近年来,量子保密通信网络发展势头迅猛,在量子保密通信网络中,量子密钥制备设备昂贵,使得量子密钥资源珍贵。因此,管控整个网络的密钥资源,是当前需要解决的重点问题。随着SDN(软件定义网络)的发展,其关键技术OpenFlow将控制层面从网络设备中脱离出来进行了集中管理,从而实现了对网络资源的灵活控制。因此,结合SDN的优势,提出了一种基于SDN的量子保密通信网络的设计方案,以利用SDN实现对全网链路及密钥资源的维护。
