Today, the number of applications using network service has been increasing. Also, many applications have changed their traffic pattern frequently due to various reasons. Nevertheless, network managers tend to stay with old signatures. But they should update with new signatures to detect the modified application traffic. The extraction of signature is work to demand a lot of time. And it is difficult to continuously and timely extract the new signature for all applications. In this paper, we propose a noble signature management system which automatically extract new signatures detecting the modified traffic and delete old signatures no longer used. The proposed system analyzes traffic with existing signatures and extracts new signature automatically for updated traffic. For automatic generation of new signatures, we uses a sequence pattern algorithm. Also, the proposed system analyze usage of the old signatures to remove them when they are not used any more. We proved the feasibility and applicability of the proposed system by showing that that detection rate of all application was increased.

Along with the widespread development of Internet and mobile applications, the demand for more flexible and dynamic networking services increases. It becomes a new challenge for many carriers to deploy a variety of new services by effective provisioning of network resources. Software-Defined Networking (SDN) is a novel approach to make networks reconfigurable and extensible such that new services can be deployed with existing network devices. By decoupling the controller plane from the data plane in network devices, SDN brings networks programmability of the data plane and centralization of the controller plane. Conventional Operations Support Systems (OSSs) were developed to manage networks in a standard fashion with Simple Network Management Protocol (SNMP) or proprietary protocols. SDN provides a new framework in managing SDN-enabled devices. A new issue for carriers is how SDN-enabled networks and devices can be monitored and controlled by current OSSs. This paper focuses on performance management and aims to develop an efficient scheme to collect traffic statistics data via the SDN controller plane. Similar to Bulkstat, an SNMP-based mechanism for periodic collection and transfer of MIB objects, the proposed scheme for bulk traffic statistics collection is developed in the controller plane and provides a northbound interface for upper network management applications. Instead of using SNMP and MIBs, the scheme is implemented by periodically gathering statistics information of flow tables from SDN-enabled switches via the OpenFlow protocol.

In OF@TEIN (OpenFlow @ Trans-Eurasian Information Network) SDN-enabled distributed cloud testbed, the resource-level visibility is extremely critical to ensure high availability of Physical+Virtual resources and identifying key performance bottlenecks which can significantly degrade testbed operation. Among multiple visibility levels for resources, flows and services, resource-level visibility is becoming crucial. To address resource-visibility challenges, we setup SmartX Visibility Center as a component solution of SmartX Operation Tower by integrating resource-level visibility tools. In this paper, we present our idea of resource-level visibility with specific focus on performance data collection, distributed resources monitoring, events alerts generation and visualization of gathered testbed operation data over large-scale networked tiled displays.

In this paper, we propose a planning mechanism based on telecom user behavior to choose locations of telecom operator's service halls. Telecom service hall network consists of service requirements nodes (RNs) and telecom service hall sites (TSs). Telecom service hall location selection problem mainly focuses on choosing locations of TSs from RNs. With analysis of base station data, we formulate a method based on telecom user distribution model to group users and to find RNs. Then, we propose a theoretical model to obtain telecom operator's greatest economic income with constraints of service satisfaction perceived by telecom users. Finally, a mechanism combined with improved genetic algorithm is put forward to solve it. Our results, supported by extensive experiments using MATLAB, confirm the feasibility and flexibility of our proposed planning mechanism.

Fault detection in wireless sensor networks is a crucial and challenging task. Many detection approaches relying on specific rules or inference models have been proposed to distinguish faulty sensors by exploring spatial-temporal correlations among sensor readings. However, these approaches may require high communication overhead or computational cost, and many potential faulty sensors that may not generate anomalous sensor readings remain undetected. In this paper, we propose a metric-correlation-based distributed fault detection (MCDFD) approach. It is motivated by the fact that the correlations between sensor nodes' system metrics usually perform regularly, whereas abnormity of such correlations indicates failures. MCDFD explores sensor nodes' internal metric correlations using correlation value matrixes. An improved cumulative summation (CUSUM) algorithm is used to track gradual changes or abrupt changes. Once any changes occur in correlation value time sequences, potential failures can be detected. The apply of metric correlations has made MCDFD with high-energy efficiency and low computational complexity, since no communication overhead is incurred and CUSUM algorithm is simple for computation. Simulation results demonstrate MCDFD performs well in respects of higher detection accuracy and lower false positive rate even under high node failure ratios and dense distribution conditions.

Nowadays, much research in recent years has focused on IoT (Internet of Things). The home domain is the most important research area of IoT, because there expected accounts of home smart device for over 40 percent of connected device excepting mobile phone. Furthermore, enormous data is generated by home smart device. There is growing concern, but the previous works didn't address enough to manage and analyze home data. The purpose of this study is to describe and examine to manage the aggregated home IoT data based on SWO (Smart home Web of Objects), and SWO analytics platform. We shows the implementation of SWO analytics platform and a case study using real data from smart metering devices for analysis of appliance usage patterns.

With the speeding-up on Internet and high maturity of Internet of Things (IoT) development, there are many kinds of composite digital services has been sprung up like mushrooms such as smart home, smart city, smart health care and etc. In recent years, the Intelligent Transportation System (ITS) has been more and more popular in transportation industry. ITS provides immediate traffic information for vehicles location tracking, vehicle dispatching, also can be used on taxi management and police cars, fire trucks, ambulance dispatching when serious accidents occur. On quality assurance, ITS involves many kinds of Information and Communication Technology (ICT) devices and services. Different services and devices have their own Operation Support System (OSS) and it is hard to exchange information. Therefore, our research proposes a framework to integrate end-to-end quality assurance information based on Digital Service Reference Architecture (DSRA) supported by TM Forum. Our framework manages all sub-systems of ITS such as Mobile virtual private network(VPN), fixed-line VPN, ITS car devices, dispatching service platform, etc. It made root cause analysis consuming time less than 10 minutem. and can improve time to market and quality assurance for ICT composite digital service.
随着互联网发展速度的加快和物联网发展的高度成熟，智能家居、智慧城市、智慧医疗等多种复合数字化服务如雨后春笋般涌现。近年来，智能交通系统(ITS)在交通运输行业得到了越来越广泛的应用。ITS为车辆位置跟踪、车辆调度提供即时交通信息，也可用于出租车管理和发生重大事故时的警车、消防车、救护车调度。在质量保证方面，智能交通系统涉及多种信息通信技术(ICT)设备和服务。不同的服务和设备都有各自的OSS (Operation Support System)，信息难以交换。因此，本研究提出了一个基于TM论坛支持的数字服务参考架构(DSRA)的端到端质量保证信息集成框架。我们的框架管理着ITS的所有子系统，如移动虚拟专用网(VPN)、固网VPN、ITS车载设备、调度服务平台等。使根本原因分析时间缩短到10分钟以内。并且可以缩短ICT复合数字服务的上市时间和质量保证。

A real-time stream recovery (RTSR) scheme is proposed to solve the problem of critical packet loss while receiving multicast streaming for recording Internet Protocol Television (IPTV) programs. Applied to time-shifted TV, RTSR not only restores program files instantly once streaming failure is detected, but also provides fluent playback to viewers when multicast streaming is interrupted. An analysis is addressed to prove that RTSR gains many more benefits than conventional recovery mechanism. Since streaming failure highly depends on actual network environment and is difficult to be predicted, a RTSR system is developed and estimated directly based on a commercial IPTV platform to ensure its feasibility. RTSR is so for the best way to guarantee time-shifted TV service against playback failure, especially in the real-time trick mode of live programs, which is proven to be the most popular time-shifted TV function.

A brand-new protocol, HTTP/2 is drawing great attention from the web industry as its standard specification is finalized and approved early this year. Since most of its technical features are inherited from SPDY, an application-layer protocol developed by Google, HTTP/2 is expected to solve many of the shortcomings and inflexibilities of HTTP/1.1, and hence enhance the web performance in terms of page load time. In this paper, we study the performance impact of HTTP/2 on typical websites in Korea, where most web pages use many different domains. To mimic the real world, we build a testbed with a web server that natively supports HTTP/2 and emulates different domains on the local system. By using the simple crawling tool and web browser supporting HTTP/2, we clone the several websites and conduct the performance evaluations under the various network environments. Simulation results show how HTTP/2 influence the page load time in typical mobile and PC web sites in Korea.

In recent years, many Communication Service Providers (CSP) plan to gradually move from telecommunication companies to cloud service providers and many third party software vendors are invited as partners of CSPs. Without an agile cloud service enabling architecture, CSPs cannot integrate their own services with partners' efficiently due to some issues. First, silo operation support system (OSS) is difficult to share data during service enabling process. Second, in-house developers and outer partners cannot understand complete metadata of service because of lack catalog management mechanism, and it makes service mash up inefficiently and inappropriately. Finally, System APIs are customized for specific service, that is, APIs are not reusable. In this paper, CHT Cloud Service Enabling Architecture is introduced to overcome issues of silo system architecture and create capacity to enable integrated cloud service efficiently.
