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 […]
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 […]
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 […]
This work analyzes the co-authorship of science papers published by university teachers, and then constructs are searcher co-authorship network and characterizes the network by some varying quantities: the clustering coefficient, the average degree, diameter, average distance and components. Consequently, this paper visualizes the researcher co-authorship network which can lead to a better understanding of the applications of information visualization […]
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 […]
In mobile computing research area, it is highly desirable to understand the characteristics of user movement so that the user friendly location aware services could be rendered effectively. Location based social networks (LBSNs) have flourished recently and are of great potential for movement behavior exploration and data-driven application design. While there have been some efforts on user check-in movement […]
Opportunistic networking poses a trade off. On the one hand, social links and the structure inherent in the opportunistic network are private information and should thus be protected. On the other hand, such information can be used to improve performance or security. We present an algorithm that can solve this dilemma: we can recognize pre-established […]
This chapter provides a general introduction to cloud networking, services, and management. It also provides an overview of cloud computing, describing its key driving forces, characteristics and enabling technologies. The chapter focuses on the different characteristics of cloud computing systems and keyresearch challenges. It also compares cloud computing with other parallel and distributed computing models and highlights their […]
Network protection against link failure is required to allow packets to reach the destination with minimal packet loss when a failure occurs. When a link fails, traffic that attempts to use the failed link is interrupted. Typically, routers in the network discover the failure and find a new route to bypass the failed link. Alternatively, well-known segment […]
IEEE 802.11s mesh networking standard supports Mesh Coordinated Channel Access (MCCA) to provide better quality of service (QoS) through channel reservation during the MAC layer channel access. According to the current QoS specifications, network traffic can be broadly classified into four classes – voice, video, background and best effort. However, MCCA does not directly support the standard […]
