최근 통신사업자들은 통신설비의 효율화 및 새로운 수익창출을 위해 하나의 공통된 IP 네트워크에서 기존의 초고속인터넷서비스에 음성서비스와 비디오서비스를 동시에 서비스하는 Triple Play Service를 제공하기 시작했다. 본 연구에서는 최근 이러한 통신서비스의 변화를 고려해 IP 네트워크에서 TPS 제공을 위한 가입자망의 대역설계 방법에 대해 몇 가지 대안을 제시하고, 제시하는 각 방법의 특성을 수치실험을 통해 비교 분석하여 가입자망의 실용적인 설계방안을 제시한다. 이를 위해 우선 연결레벨에서 초고속인터넷서비스와 프리미엄서비스를 위한 대역설계 방법을 제시하고, 두 서비스가 대역을 공유하는 TPS 환경에서 각 서비스의 서비스 품질을 보장하기 위해 가입자 수용장치의 대역을 논리적으로 분리하여 대역을 설계하는 방법을 제안한다. 그리고 제안된 방법을 바탕으로 ns-2를 이용해 가입자의 규모에 따른 설계대역량을 제시한다. 또한 프리미엄서비스의 서비스 품질을 보장하기 위해 앞서 산출한 연결레벨의 설계대역량을 이용해 패킷레벨에서 DiffServ 기반의 엄격한 우선순위스케줄링 방식을 통한 차별화된 서비스 제공방안을 가정해 기존의 FIFO 방식과 성능실험을 통해 비교 분석한다. Recently, Internet service providers are offering triple play service which combines voice and video services with the existing high speed Internet service under the common network infrastructure of IP protocol, so that they can create more benefit from operating a single network architecture. In line with this movement in the convergence of network and services, in this work we propose a bandwidth dimensioning method for the subscriber network of the IP network at flow level. To that purpose, let us propose a series of bandwidth dimensioning methods: bandwidth for best effort service only, bandwidth dimensioning for premium services, and bandwidth dimensioning schemes for the premium Internet services as well as the best effort service which comprise the TPS. Our link dimensioning method is based on the flow level that incorporates the flow blocking probability as a measure of grade of services(GoS), and investigates the characteristics of the proposed methods via extensive numerical experiments. After that, let us carry out a simulation experiment concerning the delay and loss performance of the packet scheduling for the premium services (QoS) using the bandwidth designed by our proposed method, via which the packet level quality of service (QoS) for the proposed link dimensioning method can be observed.

In recent years, many emerging technologies such smart devices and mobile internet and social media have worked to increased openness and interactions among public policy consumers. Consequently, both structured and unstructured social big data is seen by many as a potential means to promote openness, transparency and to enhance new democratic governance. Social big data analytics, in particular, has been used in many prominent, comprehensive analytical efforts in a number of e-Government and policy PR studies. While some of these efforts have received considerable attention, the issue of whether these new analytics have the potential to create a substantive change in methodologies for policy PR research has not been widely considered. This paper explores the potential impacts of social big data analytics on policy communication studies and new digital governance in terms of sustainable bottom-up decision making process via public deliberation in the smart media ecosystem of the 21 century.

The purpose of this study is to examine how major financial firms in South Korea enact utilize facebook fan-pages for relational maintenance and strategic communication in response to the socio-political and regulatory changes on financial consumer protection under the light of an issue management perspective. Specifically, this study aims to investigate whether different types of financial firms display different levels of relational maintenance strategies, message strategies, and communication tools presented in their facebook fan-pages in 2013 when the societal issues and political agenda of financial consumer protection and welfare were developed and embodied in the financial marketplace. To this end, 716 relational maintenance strategies, 316 cover-stories, and 7569 corporate posting messages presented in 77 financial firms’ facebook fan-pages were analyzed for the presence and quality of variables identified in the public relations and advertising literature as measures of relational maintenance strategies, financial services advertising appeals, and services integrated marketing communication. Results show that despite the increasing adoption of the facebook communication practice and the importance of financial consumer protection, many financial firms still do not seem to harness the unique potential of a facebook to the fullest extent for building and maintaining relationships with the public. However, financial firms differently use message strategies in cover-stories and communication tools in posting messages to maximize the effectiveness of their advertising and promotion efforts in conjunction with the scope and level of financial consumer protection issues. This paper is the fist attempt to provide a longitudinal overview of the state of financial firms’ facebooks and strategies. In addition, this paper give an insight into how financial firms’ facebook fan-pages can serve as a real issue management tool in helping to promote financial consumer welfare.
