APIs for QoS configuration in Software Defined Networks

The OpenFlow (OF) protocol is widely used in Software Defined Networking (SDN) to realize the communication between the controller and forwarding devices. OF allows great flexibility in managing traffic flows. However, OF alone is not enough to build more complex SDN services that require complete control and management of the data plane (e.g. configurations of ports, queues, etc.).The current […]

IASS: An intelligence access selection scheme for heterogeneous networks

In heterogeneous network environment, it is important to choose an appropriate access network for a Multimode Mobile Terminal (MMT). Currently, there are some methods proposed to make network access selection decision. However, those methods didn’t consider some dynamic attributes and could not offer effective handoff strategies. In this paper, we introduce an Intelligence Access Selection Scheme for Heterogeneous Networks […]

Seamless integration of Cloud and Fog networks

This work provides a way to merge Cloud Computing infrastructures with traditional or legacy network deployments, leveraging the best in both worlds and enabling a logically centralized control for it. A solution is proposed to extend existing Cloud Computing software stacks so they are able to manage networks outside the Cloud Computing infrastructure, by extending the internal, virtualized network […]

Extending OpenFlow for SDN-enabled synchronous Ethernet networks

There is an increasing need of synchronization and clock frequency distribution in core and accessnetworks. Synchronous Ethernet (SyncE) is a technology that is able to distribute clock frequency over Ethernet networks, while keeping scalability and reduced costs. Software-Defined Networking (SDN) is another emerging technology that is changing the landscape of network management by separating the control and […]

Survivable virtual infrastructure mapping with dedicated protection in transport software-defined networks [Invited]

Efficiently mapping multiple virtual infrastructures (VIs) onto the same physical substrate with survivability is one of the fundamental challenges related to network virtualization in transport software-defined networks (T-SDNs). In this paper, we study the survivable VI mapping problem in T-SDNs with the objective of minimizing the VI request blocking probability. In particular, we address the subproblems […]

A Survey of Security Attacks in Information-Centric Networking

Information-centric networking (ICN) is a new communication paradigm that focuses on content retrieval from the network regardless of storage location or physical representation of this content. In ICN, securing the content itself is much more important than securing the infrastructure or the end-points. To achieve the security goals in this new paradigm, it is crucial to have a comprehensive […]

A design of 10 Gigabit Capable Passive Optical Network(XG-PON1) architecture based on Software Defined Network(SDN)

A SDN-based XG-PON1 Network Architecture is proposed. A XG-PON1 includes many management technologies that is ONU Management, DHCP Server Management, AAA Server Management, OLT Switch Control, PIU(PON Interface Unit) Control, and OMCI. We proposed a SDN-based XG-PON1 Architecture to manage these functions.

Social Networking Reduces Peak Power Consumption in Smart Grid

Minimizing the peak power consumption of electrical appliances under delay requirements is shown to be NP-hard. To address this, we propose a “family plan” approach that partitions users into groups and schedules users’ appliances to minimize the peak power consumption of each group. Our scheme leverages the social network topology and statistical energy usage patterns of users. To partition […]

State abstraction and management in software-defined networks

SDN-enabled networks offer a great degree of flexibility, programmability and support for multiple applications. Applications running on top of a SDN controller could further benefit if network state information were made available to them as part of the SDN framework. Our work investigates the requirements for abstracting network state on the control plane. We intend to show […]

A feasible method to combat against DDoS attack in SDN network

In Software Defined Network, the controller is so vulnerable to flooding attack. By injecting spoofed request packets continuously, attackers make a burdensome process to the controller, cause bandwidth occupation in the controller-switch channel, and overload the flow table in switch. The final target of attackers is to downgrade or even shutdown the stability and quality of service […]
