Multi-constrained Quality of Service (QoS) routing algorithm is always a difficult problem in routing research area, which is a NP problem. Software Defined Network (SDN) is a new network architecture, in which there’s few research on QoS routing. This paper generates the whole network virtual topology according to the characteristics of SDN, and based on the principle of simulated annealing, p...

The advent of SDN has brought a plethora of new architectures and controller designs for many use-cases and scenarios. Existing SDN deployments focus on campus, datacenter and WAN networks. However, little research efforts have been devoted to the scenario of effectively controlling a full deployment of end-nodes (e.g. smartphones) that are transient and scattered across the Internet. In this p...

Software-defined networking (SDN) is an emerging architecture that offers advantages over traditional network architecture. Segment routing (SR) defines the path of information through the network via an ordered list of multi-protocol label switching (MPLS) mechanisms on the packet headers at the ingress device, and this system makes SDN routing management more simple and efficient. SR can also...

Networking for big data has to be intelligent because it will adjust data transmission requirements adaptively during data splitting and merging. Software-defined networking (SDN) provides a workable and practical paradigm for designing more efficient and flexible networks. Matching strategy in the flow table of SDN switches is most crucial. In this paper, we use a classification approach to an...

This work proposes a multicast algorithm on the basis of the extended Dijkstra’s shortest path algorithm for Software Defined Networking (SDN) to run on top of the controller. The proposed muticast algorithm is used to generate a multicast tree for a data publisher to deliver data packets to all subscribers so that every node and every host on the multicast tree will receive every packet once a...

Managing today’s computer networks is a complex and error-prone task. These networks consist of a wide variety of devices, from routers and switches, to firewalls, network-address translators, load balancers, and intrusion-detection systems. Network administrators must express policies through tedious box-by-box configuration, while grappling with a multitude of protocols and baroque, vendor-sp...

Recent progress in semantic segmentation has been driven by improving the spatial resolution under Fully Convolutional Networks (FCNs). To address this problem, we propose a Stacked Deconvolutional Network (SDN) for semantic segmentation. In SDN, multiple shallow deconvolutional networks, which are called as SDN units, are stacked one by one to integrate contextual information and guarantee the...

Software Defined Networking (SDN) is a new network architecture where network control is decoupled from forwarding and is directly programmable. However, existing techniques provide limited support for stateful forwarding in SDN data plane. Relying on the controller for all state maintaining gives rise to scalability and performance issues. In this paper, we present Stateful Forwarding Abstract...

We trace the intellectual underpinnings of software defined networking (SDN) to earlier research threads spanning nearly 20 years and including active networking, early efforts to separate the control and data plane, and more recent work on a specific approach to SDN, namely the OpenFlow API. We highlight key concepts, as well as the technology pushes and application pulls that spurred each inn...

Energy efficiency in Wireless Sensor Networks (WSNs) has always been a hot issue and has been studied for many years. Sleep Scheduling (SS) mechanism is an efficient method to manage energy of each node and is capable to prolong the lifetime of the entire network. In this paper a Software-defined Network (SDN) based Sleep Scheduling algorithm SDN-ECCKN is proposed to manage the energy of the ne...
