Both mobile and cloud computing are two areas which are rapidly expanding in terms of use case and functionality. Whilst mobile computing enables a variety of feature rich functionality for users in a non-fixed location, cloud computing is revolutionising the way in which computing resources are being provisioned, used and optimised for both service providers and end users. These two fields are being combined in order to provide greater functionality for mobile devices by off loading resources to the cloud. However, the advantages of this only hold true if the device resources are truly optimised. This paper examines the effect of network simulation on understanding methods for optimising device life and suggests a number of ways in which software-defined-networking (SDN) may be leveraged in order to determine the exact nature of optimisations available through this combination.

In software-defined networking, flow tables of OpenFlow switches are implemented by ternary content addressable memory (TCAM). Although TCAM can process input packets in high speed, it is a scarce and expensive resource providing only a few thousands of rule entries on a network switch. Rules caching is a technique to solve the TCAM capacity problem. However, the rule dependency problem is a challenging issue for wildcard rules caching where packets can mismatch rules. In this paper, we use a cover-set approach to solve the rule dependency problem and cache important rules to TCAM. We also propose a rule cache replacement algorithm considering the temporal and spatial traffic localities. Simulation results show that our algorithms have better cache hit ratio than previous works.

The capability of a network is ultimately bounded by limitations of the devices that compose it. In this paper we argue that software-defined networking (SDN) can increase the importance of certain limitations, such as the size and the flexibility of switches forwarding tables. In particular we focus on the implications of reactive installation of flow entries in the switch fabric: by analyzing traffic traces captured in different scenarios we show the existence of a trade-off between the size of the flow table and the rate of dynamic installation of a missing or expired rule. We leverage on this finding to further show that reactive flow (re-) configuration is a promising mechanism for improving the traffic engineering flexibility with no additional requirement in terms of flow table size. We examine links located in various parts of the network and we consider different flow definitions to evaluate the feasibility of using SDN controllers in both access and core network scenarios.

software-defined networking (SDN) is a networking paradigm that has redefined the term network by making the network devices programmable. SDN helps network engineers to monitor the network expeditely, control the network from a central point, identify malicious traffic and link failure in easy and efficient manner. Besides such flexibility provided by SDN, it is also vulnerable to attacks such as DDoS which can halt the complete network. To mitigate this attack, the paper proposes to classify the benign traffic from DDoS attack traffic by using machine learning technique. The major contribution of this paper is identification of novel features for DDoS attack detections. Novel features are logged into CSV file to create the dataset and machine learning algorithms are trained on the created SDN dataset. Various work which has already been done for DDoS attack detection either used a non-SDN dataset or the research data is not made public. A novel hybrid machine learning model is utilized to perform the classification. Results show that the hybrid model of Support Vector classifier with Random Forest (SVC-RF) classifies the traffic with the highest testing accuracy of 98.8% with a very low false alarm rate.

Deep Learning Empowered Traffic Offloading in Intelligent software defined Cellular V2X Networks

The ever-increasing and unbalanced traffic load in cellular vehicle-to-everything (C-V2X) networks have increased the network congestion and led to user dissatisfaction. To relieve the network congestion and improve the traffic load balance, in this paper, we propose an intelligent software defined C-V2X network framework to enable flexible and low-complexity traffic offloading by decoupling the network data plane from the control plane. In the data plane, the cellular traffic offloading and the vehicle assisted traffic offloading are jointly performed. In the control plane, deep learning is deployed to reduce the software defined network (SDN) control complexity and improve the traffic offloading efficiency. Under the proposed framework, we investigate the traffic offloading problem, which can be formulated as a multi-objective optimization problem. Specifically, the first objective maximizes the cellular access point (AP) throughput with consideration of the load balance by associating the users with the APs. The second objective maximizes the vehicle throughput with consideration of the vehicle trajectory by associating the delay-insensitive users with the vehicles. The two objectives are coupled by the association between the cellular APs and the vehicles. A deep learning based online-offline approach is proposed to solve the multi-objective optimization problem. The online stage decouples the optimization problem into two sub-problems and utilizes the 'Pareto optimal' to find the solutions. The offline stage utilizes deep learning to learn from the historical optimization information of the online stage and helps predict the optimal solutions with reduced complexity. Numerical results are provided to validate the advantages of our proposed traffic offloading approach via deep learning in C-V2X networks.

Application-Aware Firewall Mechanism for software defined Networks

software-defined-networking (SDN) has been recently arising as a new technology in the IT industry. It is a network architecture that hopes to provide better solutions to most of the constraints in contemporary networks. SDN is a centralized control architecture for networking in which the control plane is separated from the data plane, the network services are abstracted from the underlying forwarding devices, and the network's intelligence is centralized in a software-based directly-programmed device called a controller. These features of SDN provide more flexible, programmable and innovative network's architecture. However, they may pose new vulnerabilities and may lead to new security problems. In this paper, we propose the application-aware firewall mechanism for SDN, which can be implemented as an extension to the network's controller. In order to provide more control and visibility in applications running over the network, the system is able to detect network applications that may at some point affect network's performance, and it is capable to dynamically enforce constraint rules on applications. The firewall architecture is designed as four cooperating modules: the Main Module, the Filtering Module, the Application Identification Module, and the Security-Enforcement Module. The proposed mechanism checks the network traffic at the network, transport, and application levels, and installs appropriate security instructions down into the network. The proposed solution features were implemented and tested using a Python-based POX controller, and the network topology was built using Mininet emulation tool.

The most well-known high-energy physics collaboration, the Large Hadron Collider (LHC), which is based on e-Science, has been facing several challenges presented by its extraordinary instruments in terms of the generation, distribution, and analysis of large amounts of scientific data. Currently, data distribution issues are being resolved by adopting an advanced Internet technology called software defined networking (SDN). Stability of the SDN operations and management is demanded to keep the federated LHC data distribution networks reliable. Therefore, in this paper, an SDN operation architecture based on the distributed virtual network operations center (DvNOC) is proposed to enable LHC researchers to assume full control of their own global end-to-end data dissemination. This may achieve an enhanced data delivery performance based on data traffic offloading with delay variation. The evaluation results indicate that the overall end-to-end data delivery performance can be improved over multi-domain SDN environments based on the proposed federated SDN/DvNOC operation framework.

Impact of SDN on Optical Router Bypass

JOURNAL OF OPTICAL COMMUNICATIONS AND networking 2018年第4期10卷 332-343页

Internet traffic is growing rapidly, driven by new applications such as the Internet of things (IoT). To overcome router scaling limitations, router bypass has been introduced. Traditional bypass is based on provisioning fixed-size bypass channels, which was shown to underutilize link capacity. In software defined networking (SDN), router bypass can be requested as a service by the application layer. This study explores the opportunity to bypass routers efficiently without the link underutilization of the traditional bypass. We combine SDN and dynamic layer provisioning to implement dynamic router bypassing and show how this leads to improved efficiency. A simulation built to compare the traditional bypass with the SDN-based bypass showed that SDN-based bypassing enhanced efficiency by 33%. When bypass traffic is increased, we show that the output capacity of a node increases up to 56%, limited by optical capacity rather than router capacity.

software-defined-networking (SDN) and Content-Centric-networking (CCN) are gathering an important consideration from academic world and manufacturing. They are perceived as a big opportunity for future Internet. In order to innovate and optimize network resources, the integration of CCN functionalities with OpenFlow architecture presents an attractive deal. However, there are deployment issues requiring a gradual approach to achieve these goals. The current specifications implementing CCN over OpenFlow have not been inspected sufficiently, although the conceptual design was investigated. This paper introduces OFAM-CCN, a new OpenFlow Architecture for Managing CCN to improve this process through new modifications based on Popularity Caching Strategy taking into account caching as a fundamental principle of CCN.
