Content-based communication is a novel communication paradigm that enables users to communicate with others based on message's content, instead of message's address. Groupware is a kind of software that supports coordination between individual users. An important feature of groupware is that the communication between the specified users is at a high frequency, which is determined by the applied coordination mechanism. Efficient communication in a groupware can support effective coordination between the users. This paper presents a topology-enhanced content-based network, which combines content-based communication with the topology between groupware users, to support content-based communication in groupware. We give a predicate-based method to define cooperation topology, which can effectively describe the topology between groupware users. We also propose a multi-level index structure to support efficient matching of cooperation topology in the forwarding mechanism of the proposed network. We implement the basic feature of our network and evaluate the prototype in a motivating scenario consisting of several coordination tasks. The results show that our method improves the message forwarding efficiency of 1 to 2 magnitude orders.

Open Shortest Path First (OSPF) is a broadly used routing protocol in today's data center networks. Though it can adaptively find alternative paths when link failure is detected, route recomputation in OSPF is CPU-intensive, and usually needs quite a long time to achieve routing convergence. Besides, the configuration in OSPF is rather complex. In this paper, we propose Sequoia Routing Protocol (SRP), a routing protocol with a dedicated shortest path calculation algorithm, designed for data center networks. By leveraging the observation that each data center has a fixed Clos topology, SRP largely simplifies routing configuration, and achieves light-weight computation. We show that SRP outperforms OSPF with a much faster convergence time by simulation in ns-3. We also implement SRP in real-world switches, showing that SRP is as efficient as OSPF even for a small-scale network where route recomputation of OSPF does not take a long time.

Business operation systems in the design period, not only consider the development of related technologies, but also the selection of different kinds of software platform solutions, such as application server and relational database are particularly important. In addition to the platform operability, cost considerations also affect a large portion of the decision results. If system programmers do not take the different business operation execution environments into consideration in the step of system development, when the system established complete, due to system requirements change or cost considerations and need to adopt other software solutions, migrate business operation systems to different application servers or relational databases will spend extra time and effort for system modifications. This paper proposed an empirical study with an instance of A&A (Authentication & Authorization) Management System (AAMS) to actually migrate between different kinds of application servers and relational databases, and proposed several common principles of system migrations and system design rules for variety of software solutions. Moreover, it reduces the time which it needed and lowers system development expenses significantly during system migration.

The Long Term Evolution (LTE) network is recognized as the next generation wireless network, which provides high bandwidth and low latency for emerging mobile applications. The issue of power saving is very crucial for the success of service deployment. This paper presents a novel downlink scheduling approach to reduce power consumption while maintaining the receiving quality of video streaming in LTE network. The proposed scheduler considers the buffer length and channel conditions of user equipment (UE) to allocate radio resource, so that the UE can receive as many video packets as possible when the UE is in the RRC_Connected state especially with good channel condition, while the UE will stay in the RRC_Idle state the longer the better to save power given that its buffered video data is enough to play. The 1080P resolution video traffic model was applied for exhaustive simulations to examine the performance of the proposed scheme. The simulation results indicate the tradeoff between the power saving and signaling message overhead issues. And the impacts of related parameters are also studied in this paper.
LTE (Long Term Evolution)网络被认为是下一代无线网络，为新兴的移动应用提供高带宽和低延迟。节能问题对业务部署的成功与否至关重要。本文提出了一种新的LTE网络下行链路调度方法，在保证视频流接收质量的同时降低功耗。该调度器考虑用户设备(UE)的缓冲区长度和信道条件来分配无线电资源，使UE在RRC_Connected状态下，特别是信道条件好的情况下，能够接收到尽可能多的视频数据包，而在其缓冲的视频数据足够播放的情况下，UE在RRC_Idle状态下保持越长越好，以节省电力。采用1080P分辨率视频流量模型进行详尽仿真，以检验所提方案的性能。仿真结果表明了在节能和信令开销问题之间的权衡。并对相关参数的影响进行了研究。

Quality of Experience (QoE) is a measure of a customer's experiences with a service (web browsing, TV broadcast, call to a Call Center). QoE focuses on the entire service experience, and is a more holistic evaluation than the more narrowly focused UX (user experience, focused on a software interface) and CX (customer experience, support focused). Measuring the bottleneck link bandwidth along a path is important for understanding the performance of many services. Existing tools to measure QoE are using distributed network probes to collect network information. It is a very costly monitoring architecture. This paper proposes a cost-effective QoE measurement architecture based on Software Defined Network (SDN) [1], adopting centralized control mechanism to measure multiple clients simultaneously. Experiments on Wi-Fi environment show great reducing of CAPEX and OPEX.
体验质量(QoE)是衡量客户使用服务(网页浏览、电视广播、呼叫中心)的体验。QoE侧重于整个服务体验，是一种更全面的评估，而不是更狭隘的UX(用户体验，专注于软件界面)和CX(客户体验，专注于支持)。测量路径上的瓶颈链路带宽对于理解许多业务的性能非常重要。现有的QoE测量工具使用分布式网络探针来收集网络信息。这是一个非常昂贵的监控体系结构。本文提出了一种基于软件定义网络(Software Defined Network, SDN)的高性价比QoE测量架构[1]，采用集中控制机制同时测量多个客户端。在Wi-Fi环境下的实验表明，该方法大大降低了CAPEX和OPEX。

With the emergence of the Long Term Evolution (LTE) technology, LTE based VoIP services are gaining more and more popularity in these days. Voice over LTE (VoLTE) is a VoIP based multimedia service on All-IP based LTE network, which was initially introduced and commercialized by Korea telecommunication companies in 2012. As more and more subscribers use VoLTE service, the VoLTE traffic volume increases, and this may in turn lower down the VoLTE quality; therefore to preserve QoS of VoLTE service, we need to periodically monitor VoLTE traffic among LTE traffic, and perform appropriate actions to LTE network. To be the first step of realizing this goal, in this paper, we propose a VoLTE traffic classification method and its distributed processing architecture to achieve high throughput. For the classification, we analyze SIP/SDP packets for VoLTE service and generate VoLTE tailored SIP packet signature using SIP User-Agent header field. Since the proposed classification method is relying on Deep Packet Inspection (DPI) method, the classification accuracy can be guaranteed, yet it suffers from the poor processing performance. Therefore, we further propose a distributed and parallel traffic processing architecture with the help of HTCondor.
随着长期演进(LTE)技术的出现，基于LTE的VoIP业务越来越受欢迎。VoLTE (Voice over LTE)是2012年国内通信公司首次推出并商用化的基于全ip (All-IP) LTE网络的VoIP多媒体服务。随着越来越多的用户使用VoLTE业务，VoLTE流量增加，这可能会导致VoLTE质量下降;因此，为了保持VoLTE业务的QoS，我们需要定期监控LTE业务中的VoLTE业务，并对LTE网络采取适当的措施。作为实现这一目标的第一步，本文提出了一种VoLTE流量分类方法及其分布式处理架构，以实现高吞吐量。在分类方面，我们分析了VoLTE业务的SIP/SDP报文，并使用SIP User-Agent报头字段生成了VoLTE定制的SIP报文签名。由于所提出的分类方法依赖于深度包检测(Deep Packet Inspection, DPI)方法，可以保证分类精度，但存在处理性能较差的问题。因此，我们进一步提出了一种基于HTCondor的分布式并行流量处理架构。

NFV, being discussed and standardized in ETSI, is regarded as a promising candidate technology for Future Networks. Although many advantages are expected, the introduction of NFV will greatly challenge current management systems. In this paper, we summarize some of the carrier's requirements for the management of NFV, based on which we propose vConductor as an NFV management solution. We say vConductor is innovative due to its characteristics of automatic service provisioning, end-to-end inventory management, and generic system design. To achieve these goals, we design a completely modular-based system structure and refine the process of provisioning a virtual network service. Furthermore, we propose a general data model, specifically for NFV, starting from the TM Forum SID. We believe that vConductor will be a catalyst for accelerating the industrialization of NFV.

Cloud computing changes the conventional way of virtualization resource allocation, and gives users high flexibility and convenience. However, when the cloud service providers offer Infrastructure as a Service (IaaS), there are many practical problems to be resolved. We propose a cloud system's prototype, through a composition of cloud services to automate workflow and exchange data between services based on Message-Oriented Middleware, and then achieve the goal of virtualization platform integration. We develop efficient schemes for users to use functions, which include a single web portal, virtual machine templates and message translation, to quickly deploy virtual machines in a large-scale.

This paper proposes a model to derive an overall assessment index of the quality for IPTV network in order to make the network faults diagnosis more efficiently. This paper also provides a systematic approach to estimate the quality index based on the packet loss events. This model has been applied to the actual operational environment, not only to regularly monitor the customer perceived quality, but also to provide discriminating rules for locating abnormal sites.
