  • Due to the development of network and device, it is called mobile age that boosts various distribution routes of multi-media content and it constructs a new digital content consumption trend. N-screen is one of the new-introduced examples in the digital age and broadcasting industry believes it as a crisis and challenge as well. It becomes a ubiquitous multi-media environment that people watch multi-media content everywhere and any time they want to and competition happens beyond the boundaries such as network industry, terminal industry, pay TV market, traditional terrestrial TV, etc. And then how should the broadcasting service prepare for the N-screen business? The present research proposes a few terrestial broadcasting content strategies in the multi platform environment. First, instead of N-screen, it proposes multi platform, especially One Source Multi Platform(OSMP). Second, so-called 'Integrated Terrestrial Broadcasting OSMP Alliance(IBPA)' must be founded. Third, IBPA should support multi-tasking UX for viewers to have rich experience. Last, it becomes more important and necessary to support local terrestrial broadcasting service for public service in the multi platform age.

  • The network function virtualization (NFV) uses virtualization technology to separate software from hardware. One of the most important challenges of NFV is the resource management of virtual network functions (VNFs). According to the dynamic nature of NFV, the resource allocation of VNFs must be changed to adapt to the variations of incoming network traffic. However, the significant delay may be happened because of the reallocation of resources. In order to balance the performance between delay and quality of service, this paper firstly made a compromise between VNF migration and energy consumption. Then, the long short-term memory (LSTM) was utilized to forecast network traffic. Also, the asymmetric loss function for LSTM (LO-LSTM) was proposed to increase the predicted value to a certain extent. Finally, an experiment was conducted to evaluate the performance of LO-LSTM. The results demonstrated that the proposed LO-LSTM can not only reduce migration times, but also make the energy consumption increment within an acceptable range.

  • 글로벌 CP들로 인해 인터넷의 트래픽이 급증하면서 망 투자비용을 분담하여야 한다는 주장이 업계에서 대두하였다. 이로 인해 망 중립성의 원칙이 접근성에서 비용 부담으로 논점이 크게 바뀌었다. 유료화된 트래픽의 우선처리가 각국에서 인정을 받았음에도 불구하고, 학계의 일부에서는 인터넷 공간에서 망 사용료 지불에 대한 부정적인 시각이 있었다. 그러나 업계에서는 사업자들 사이에 분쟁이 다수 발생하였고, 일부는 법정 다툼으로 비화되면서 법원의 판결에 관심이 쏠렸다. 법원이 망 중립성 하에서 유상성을 인정하기 시작하였고, 정부도 이에 대응하여 규제를 정비하는 등 우리나라는 빠르게 대처해 왔다. 그러나 여전히 서비스 안정에 초점을 맞추고 있으며, 직접적으로 망 이용대가의 지불을 규정한 규제는 아직 없다. 본 연구에서는 망 중립성에 대한 사업자간 분쟁 및 법원의 판결, 규제의 개선 사례를 분석하여 망 중립성의 변화를 고찰하였으며, 공유지의 비극 사례를 참고하여 수익자 부담의 원칙에 입각한 올바른 가격신호의 복원이 가장 중요한 해결책임을 제시하였다. CP의 망 사용료 지급도 그 방안의 하나이다.

  • In the telecommunication industry, estimation of the cost of network facilities is very important since depreciation cost of the facilities accounts for a large portion of the product cost. Moreover, cost estimation in the industry becomes more difficult because of increasing indirect cost upon digital convergence, expanding multi-purpose facilities, complexity of service product, etc. Nevertheless, not much seem to have been done in improving estimation methodology of the cost of network facilities. As a result, the quality of cost information on network facilities has deteriorated, and now even decision-makers in the industry dismiss the information. Recently, two major telecommunication companies adopted a new network cost estimation method to deal with the issue. In this paper, we study the concept of new cost estimation method and the procedure to develop and apply it. We also suggest the method to carry out the cost allocation using Matlab which is more efficient and time-saving than other commercial cost calculation packages.
