Software Defined Networks-Based Smart Grid Communication: A Comprehensive Survey

Abstract: The current power grid is no longer a feasible solution due to ever-increasing user demand of electricity, old infrastructure, and reliability issues and thus require transformation to a better grid also known as, smart grid (SG). The key features that distinguish SG from the conventional electrical power grid are its capability to perform two-way communication, demand side management, and real time pricing. Despite all these advantages that SG will bring, there are certain issues which are specific to SG communication (SGC) system. For instance, network management of current SG systems is complex, time consuming, and done manually. Moreover, SGC system is built on different vendor specific devices and protocols. Therefore, the current SG systems are not protocol independent, thus leading to interoperability issue. Software defined network (SDN) has been proposed to monitor and manage the communication networks globally. By separating the control plane from the data plane, SDN helps the network operators to manage the network flexibly. Since SG heavily relies on communication networks, therefore, SDN has also paved its way into the SG. By applying SDN in SG systems, efficiency and resiliency can potentially be improved. SDN, with its programmability, protocol independence, and granularity features, can help the SG to integrate different SG standards and protocols, to cope with diverse communication systems, and to help SG to perform traffic flow orchestration and to meet specific SG quality of service requirements. This paper serves as a comprehensive survey on SDN-based SGC. In this paper, we first discuss taxonomy of advantages of SDN-based SGC. We then discuss SDN-based SGC architectures, along with case studies. This paper provides an in-depth discussion on routing schemes for SDN-based SGC. We also provide detailed survey of security and privacy schemes applied to SDN-based SGC. We furthermore present challenges, open issues, and future research directions related to SDN-based SGC.

Method and system for managing a directory service

Abstract: A method and system for managing a distributed directory service. The method includes defining a plurality of objects operative to maintain information about a plurality of partitions in a MIB, implementing the MIB in an agent, loading the agent on a managed server, interfacing the agent with a directory service, and sending a management request from a management station to the agent to access one of the objects. The MIB maintains information about each partition on the managed server, and allows access to such information through conventional network management software.

DDoSNet: A Deep-Learning Model for Detecting Network Attacks

Abstract: Software-Defined Networking (SDN) is an emerging paradigm, which evolved in recent years to address the weaknesses in traditional networks. The significant feature of the SDN, which is achieved by disassociating the control plane from the data plane, facilitates network management and allows the network to be efficiently programmable. However, the new architecture can be susceptible to several attacks that lead to resource exhaustion and prevent the SDN controller from supporting legitimate users. One of these attacks, which nowadays is growing significantly, is the Distributed Denial of Service (DDoS) attack. DDoS attack has a high impact on crashing the network resources, making the target servers unable to support the valid users. The current methods deploy Machine Learning (ML) for intrusion detection against DDoS attacks in the SDN network using the standard datasets. However, these methods suffer several drawbacks, and the used datasets do not contain the most recent attack patterns - hence, lacking in attack diversity. In this paper, we propose DDoSNet, an intrusion detection system against DDoS attacks in SDN environments. Our method is based on Deep Learning (DL) technique, combining the Recurrent Neural Network (RNN) with autoencoder. We evaluate our model using the newly released dataset CICDDoS2019, which contains a comprehensive variety of DDoS attacks and addresses the gaps of the existing current datasets. We obtain a significant improvement in attack detection, as compared to other benchmarking methods. Hence, our model provides great confidence in securing these networks.

A method and a system relating to network management

Abstract: The present invention relates to a method for network management comprising configuration of control protocols between network elements in a network represented through a current, static, network element object model comprising a number of managed objects with attributes and instances and representing resources. It comprises the steps of : transforming the current network element object model to a machine readable and executable formal network element object model; identifying configuration tasks needed for the configuration of the relevant control protocols; modelling a formal configuration task model using information about the configuration tasks and the formal network element object model; building a formal configuration workflow model using the formal network element object model and the formal configuration task model, said formal configuration workflow model defining the relationships between different configuration tasks required for performing or completing a number of given actions or to achieve a number of given goals.
