2 MARVEL: Enabling controller load balancing in software-defined networks with multi-agent reinforcement learning
MARVEL: امکان ایجاد توازن بار کنترل کننده در شبکه های تعریف شده توسط نرم افزار با یادگیری تقویتی چند عامل-2020
The control plane plays a significant role in Software-Defined Networking (SDN). A large SDN usually implements its control plane with several distributed controllers, each controlling a subset of switches and synchronizing with other controllers to maintain a consistent network view. Under the fluctuating network traffic, a static controller- switch mapping relationship could lead to imbalanced workload allocation. Controllers may getoverloaded and reject new requests, eventually reducing the control plane’s request processing ability. Most existing schemes have relied heavily on iterative optimization algorithms to manipulate the mapping relationship between con- trollers and switches, which are either time-consuming or less satisfactory in terms of performance. In this paper, we propose a dynamic controller workload balancing scheme, that is termed MARVEL, based on multi-agent re- inforcement learning for generation of switch migration actions. MARVEL works in two phases: offline training and online decision making. In the training phase, each agent learns how to migrate switches through interacting with the network. In the online phase, MARVEL is deployed to make decisions on migrating switches. Experimen- tal results show that MARVEL outperforms competing existing schemes by improving the control plane’s request processing ability at least 27.3% while using 25% less processing time.

3 SmartFCT: Improving power-efficiency for data center networks with deep reinforcement learning
SmartFCT: بهبود بهره وری انرژی برای شبکه های مرکز داده با یادگیری تقویتی عمیق-2020
Reducing the power consumption of Data Center Networks (DCNs) and guaranteeing the Flow Completion Time (FCT) of applications in DCNs are two major concerns for data center operators. However, existing works cannot realize the two goals together because of two issues: (1) dynamic traffic pattern in DCNs is hard to accurately model; (2) an optimal flow scheduling scheme is computationally expensive. In this paper, we propose SmartFCT, which employs the Deep Reinforcement Learning (DRL) coupled with Software-Defined Networking (SDN) to improve the power efficiency of DCNs and guarantee FCT. SmartFCT dynamically collects traffic distribution from switches to train its DRL model. The well-trained DRL agent of SmartFCT can quickly analyze the complicated traffic characteristics using neural networks and adaptively gen- erate a action for scheduling flows and deliberately configuring margins for different links. Following the gen- erated action, flows are consolidated into a few of active links and switches for saving power, and fine-grained margin configuration for active links avoids FCT violation of unexpected flow bursts. Simulation results show that SmartFCT can guarantee FCT and save up to 12.2% power consumption, compared with the state-of-the-art solutions.

4 QoS provisioning for various types of deadline-constrained bulk data transfers between data centers
تامین کیفیت سرویس برای انواع مختلف انتقال داده های فشرده محدود بین مراکز داده-2020
An increasing number of applications in scientific and other domains have moved or are in active transition to clouds, and the demand for big data transfers between geographically distributed cloudbased data centers is rapidly growing. Many modern backbone networks leverage logically centralized controllers based on software-defined networking (SDN) to provide advance bandwidth reservation for data transfer requests. How to fully utilize the bandwidth resources of the links connecting data centers with guaranteed quality of service for each user request is an important problem for cloud service providers. Most existing work focuses on bandwidth scheduling for a single request for data transfer or multiple requests using the same service model. In this work, we construct rigorous cost models to quantify user satisfaction degree, and formulate a generic problem of bandwidth scheduling for multiple deadline-constrained data transfer requests of different types to maximize the request scheduling success ratio while minimizing the data transfer completion time of each request. We prove this problem to be not only NP-complete but also non-approximable, and hence design a heuristic algorithm. For performance evaluation, we establish a proof-of-concept emulated SDN testbed and also generate large-scale simulation networks. Both experimental and simulation results show that the proposed scheduling scheme significantly outperforms existing methods in terms of user satisfaction degree and scheduling success ratio.

6 Optimal Decision Making for Big Data Processing at Edge-Cloud Environment: An SDN Perspective
تصمیم گیری بهینه برای پردازش داده های بزرگ در محیط لبه-ابر: چشم انداز SDN-2018
With the evolution of Internet and extensive usage of smart devices for computing and storage, cloud computing has become popular. It provides seamless services such as e-commerce, e-health, e-banking, etc., to the end users. These services are hosted on massive geodistributed data centers (DCs), which may be managed by different service providers. For faster response time, such a data explosion creates the need to expand DCs. So, to ease the load on DCs, some of the applications may be executed on the edge devices near to the proximity of the end users. However, such a multiedge-cloud environment involves huge data migrations across the underlying network infrastructure, which may generate long migration delay and cost. Hence, in this paper, an efficient workload slicing scheme is proposed for handling data-intensive applications in multiedgecloud environment using software-defined networks (SDN). To handle the inter-DC migrations efficiently, an SDN-based control scheme is presented, which provides energy-aware network traffic flow scheduling. Finally, a multileader multifollower Stackelberg game is proposed to provide costeffective inter-DC migrations. The efficacy of the proposed scheme is evaluated on Google workload traces using various parameters. The results obtained show the effectiveness of the proposed scheme.

7 Big Data Analysis-Based Secure Cluster Management for Optimized Control Plane in Software-Defined Networks
مدیریت خوشه امن مبتنی بر تحلیل داده های بزرگ برای کنترل بهینه هواپیما در شبکه های تعریف شده توسط نرم افزار-2018
In software-defined networks (SDNs), the abstracted control plane is its symbolic characteristic, whose core component is the software-based controller. The control plane is logically centralized, but the controllers can be physically distributed and composed of multiple nodes. To meet the service management requirements of large-scale network scenarios, the control plane is usually implemented in the form of distributed controller clusters. Cluster management technology monitors all types of events and must maintain a consistent global network status, which usually leads to big data in SDNs. Simultaneously, the cluster security is an open issue because of the programmable and dynamic features of SDNs. To address the above challenges, this paper proposes a big data analysis-based secure cluster management architecture for the optimized control plane. A security authentication scheme is proposed for cluster management. Moreover, we propose an ant colony optimization approach that enables big data analysis scheme and the implementation system that optimizes the control plane. Simulations and comparisons show the feasibility and efficiency of the proposed scheme. The proposed scheme is significant in improving the security and efficiency SDN control plane.

8 Optimized Big Data Management across Multi-Cloud Data Centers: Software-Defined Network-Based Analysis
مدیریت داده های بزرگ بهینه شده در سراسر مراکز داده چند ابری: تحلیل مبتنی بر شبکه نرم افزار تعریف شده-2018
With an exponential increase in smart device users, there is an increase in the bulk amount of data generation from various smart devices, which varies with respect to all the essential Vs used to categorize it as big data. Generally, most service providers, including Google, Amazon, Microsoft and so on, have deployed a large number of geographically distributed data centers to process this huge amount of data generated from various smart devices so that users can get quick response time. For this purpose, Hadoop, and SPARK are widely used by these service providers for processing large datasets. However, less emphasis has been given on the underlying infrastructure (the network through which data flows), which is one of the most important components for successful implementation of any designed solution in this environment. In the worst case, due to heavy network traffic with respect to data migrations across different data centers, the underlying network infrastructure may not be able to transfer data packets from source to destination, resulting in performance degradation. Focusing on all these issues, in this article, we propose a novel SDN-based big data management approach with respect to the optimized network resource consumption such as network bandwidth and data storage units. We analyze various components at both the data and control planes that can enhance the optimized big data analytics across multiple cloud data centers. For example, we analyze the performance of the proposed solution using Bloom-filter-based insertion and deletion of an element in the flow table maintained at the OpenFlow controller, which makes most of the decisions for network traffic classification using the rule-and-action-based mechanism. Using the proposed solution, developers can deploy and analyze real-time traffic behavior for the future big data applications in MCE.

9 Leveraging the Big Data Produced by the Network to Take Intelligent Decisions on Flow Management
بهره برداری از داده های بزرگ تولید شده توسط شبکه تصمیم گیری هوشمندانه بر روی مدیریت جریان-2018
Software-defined network (SDN) offers a very advantageous feature of programming the network at run time by decoupling the control plane from data plane to have centralized and better forwarding decisions. To attain the maximum throughput and relatively less latency within a large network, we have captured the real-time big data produced by the network. Big data is revolutionizing the modern computer science world to analyze the extremely large datasets to predict the future requirements. Therefore, it would be useful to embed intelligence in the systems. With the power of SDN, we programmed our network at run time using Ryu controller to dump the network traffic and engineer it accordingly. We proposed a methodology for taking intelligent decisions with traffic engineering in SDN. Results have shown that SDN leverages the big data to decrease the latency time by adding programs in the controller of SDN. An algorithm is presented to maximize the bandwidth utilization to possess higher throughput after shaping the traffic. It is found through the results that our proposed methodology of applying intelligence on traffic management in SDN outperforms those without intelligence decision making.

10 Proactive defense mechanisms for the software-defined Internet of Things with non-patchable vulnerabilities
مکانیسم های دفاعی بیش فعال برای اینترنت اشیا نرم افزار-تعریف شده با آسیب پذیری های غیر قابل آسیب پذیری-2017
The Internet of Things (IoT) contains a large number of heterogeneous devices with a variety of vul nerabilities. As the vulnerabilities can be exploited by the attackers to break into the system, it is of vital importance to patch all vulnerabilities. However, some vulnerabilities are impossible to patch (e.g., forever-day vulnerabilities). In order to deal with non-patchable vulnerabilities, we propose to change the attack surface of the IoT network to increase the attack effort. With the support of software-defined networking (SDN), we develop two proactive defense mechanisms that reconfigure the IoT network topology. We analyze how the security and performance change when the proposed solutions are deployed by using a graphical security model and various metrics in simulations. The results show our proactive defense mechanisms in the SD-IoT effectively increase the attack effort, while maintaining the average shortest path length.
