The migration of virtual router has attracted a lot of attention from researchers in the new network architecture field, due to the potential to cope with emerging challenges, such as energy consumption and resource fragmentation problem. In this paper, we focus on general virtual router architecture VRSM (Virtual Router Supporting Migration), composed by a cluster of servers. Compared with other architectures, VRSM introduces intelligently interface plane, management switch and data switch. The interface plane is used to switch data traffic to new forward instances and other two switches can guarantee bandwidth separation between migration traffic and data traffic in migration process. Based on VRSM architecture, we put forward a migration strategy DMVR (Dynamic Migration of Virtual Router), which can dynamically migrate a virtual router instance from one physical server to another without disrupting the network topology. Our experiment shows that DMVR strategy results in minimal impact in the data plane and brief downtime in the control plane.
虚拟路由器的迁移由于具有应对能源消耗和资源碎片化等新挑战的潜力，引起了新网络架构领域研究者的广泛关注。本文主要研究由服务器集群组成的通用虚拟路由器体系结构VRSM (virtual router support Migration)。与其他架构相比，VRSM引入了智能接口平面、管理交换机和数据交换机。接口平面用于将数据流量切换到新的转发实例，另外两个交换机可以保证迁移过程中迁移流量和数据流量的带宽隔离。基于VRSM架构，提出了虚拟路由器动态迁移策略DMVR (Dynamic migration of Virtual Router)，该策略可以在不破坏网络拓扑结构的情况下，将虚拟路由器实例从一台物理服务器动态迁移到另一台物理服务器。我们的实验表明，DMVR策略在数据平面上的影响最小，在控制平面上的停机时间很短。

Complex field network coding can earn larger diversity gain, better system reliability and higher network throughput in wireless communication with relay cooperative. An improved complex filed network coding scheme for large scale density network with user clustering and relay selection strategy will be proposed in this paper. The multiuser detector we employ is not based on maximum likelihood algorithm, but based on complex filed belief propagation algorithm improved from belief propagation decode algorithm of low density parity check code. As the same time, network decoding and channel decoding are combined together to form a joint network channel iterative decoder, in which the extrinsic information derive from network decode and that derive from channel decode can work well for each other. Numerical results are given to illustrate that our proposed scheme can provide better reliability, larger network diversity gain and higher throughput, more importantly, it can be well applied to large scale dense network when compared with traditional schemes.

This paper presents a new architecture of super regenerative On-Off keying receiver (SROOK RX) applying to the 5.8GHz Industrial Scientific Medical (ISM) band in TSMC 0.18 μm process. The proposed SROOK Rx uses a quenched oscillator to reduce the required gain of Low Noise Amplifier (LNA) and can achieve low power consumption. The technology of pulse width demodulator employs the Pulse-Width Expander (PWE) to convert the pulse into digitally binary level and achieves fine resolution, which allows the SROOK Rx to support OOK demodulation. To improve the sensitivity and reduce demodulation difficulty, a high-speed comparator is added between the Envelope Detector (ED) and PWE. From simulation results, the whole receiver consumes 7mW from 0.6V/1.2V supply voltages and achieves data rate of 6 Mbps and sensitivity of -115dBm (hence energy efficiency of 1.17nJ/bit). The core area is 1.2×0.8 mm2.

It is challenging to achieve network load balancing, simultaneously meeting the quality of service (QoS) demands of bandwidth and delays. In this paper we have designed and implemented a multicast routing system over Software Defined Networking (SDN) and sFlow. The system has been developed on the top of RYU controller. Our main contributions are: (1) compatibility of our system with traditional multicast applications which are based on the Internet Group Management Protocol (IGMP) v2 and multicast address; (2) choosing the optimum paths for multicast applications on the basis of currently available network bandwidth which is calculated accurately by sFlow; (3) reduction in unnecessary network traffic effectively and load balancing, thereby reducing the packet loss rate and delay in the multicast.

The rapid progress of cloud technology has attracted a growing number of video providers to deploy their streaming services onto multiple distributed datacenters for more cost-effective performance. The emerging Software-Defined Networking (SDN) technology overcomes the limitation of the existing network and provides a promising solution to manage the underlying network. In this paper, we introduce an SDN-enabled cloud video distribution architecture and propose a joint resource allocation and traffic management mechanism to improve user experience and reduce the system operational cost. We use a delay utility function to represent user experience and formulate the joint optimization problem as a convex optimization problem. We conduct simulations to evaluate the performance of our algorithm and the results show that our strategy can effectively cut down the total cost and guarantee user experience.

In microblogging, information influence is very hard to be measured. Because there are a lot of spam messages, and these messages were retweeted and commented by a lot of spam users in microblogging. Early methods for a message influence measurement mainly use message retweet and comment times. But they don't consider the quality of user, who takes part in the information diffusion. In this paper, we propose a novel measurement method based on user quality and information attribute. Experimental results show that our method can measure the influence more accurately and reduce the spam message influence in the dataset more effectively.

The task of moving object segmentation is to partition an object into non-overlapping regions based on intensity or texture information. However, the conventional segmentation methods suffer from false object segmentation in complex backgrounds and slow convergence. In this paper, we propose an efficient segmentation algorithm for moving object with complicated structures in real video environment. Our novel approach, which integrates an adaptive single Gaussian model (SGM) with a generalized geodesic active contour (GGAC) model, is put forward to detect and segment moving objects in dynamic backgrounds. The proposed algorithm is implemented by level set method to reduce the expensive computational cost of re-initialization of the traditional level set function. By utilizing both spatial and temporal information, this integrated method is robust to complex environments. Experimental results demonstrate desirable segmentation improvement over widely used segmentation algorithms in terms of efficiency and accuracy.

Digital IF (Intermediate Frequency) is an indispensable key technology in modern communication, among which digital up converter (DUC) and digital down converter (DDC) are important parts between baseband and IF. In this paper, we give a general method and solution of designing digital IF to meet the demands of practical application. Firstly, we analyze the theories and technologies of digital IF including filter bank and DUC. Secondly, we set about analyzing how to design filter bank in key part and implement a superheterodyne. Finally, we put forward a specific design plan of DUC and develop a digital IF suitable for TDD-LTE (Time Division Long Term Evolution) system.
