Policy-based networking offers a network manager the ability to manage the network in a holistic and dynamic fashion rather than force a network manager to manage the network by dealing with each device individually. Policy-based networking is focusing on users and applications instead of emphasizing devices and interfaces. An important part of the policy-based networking is to simplify the task of administration and management for different disciplines. The Defense Information System(DIS) of today are complex and heterogeneous systems. Operational needs are not a trivial task and Quality of Service(QoS) is not generally guaranteed. So, important data may be missed or congested by trivial data. Policy-based networking provide a way to support QoS and simplify the management of multiple devices deploying complex technologies. This paper suggest implementation of policy-based networking in DIS to improvement of performance, and implementation is progressed step by step. Especially this paper is focusing on the providing QoS with policy-based networking using Lightweight Directory Access Protocol(LDAP) Server.

최근 인터넷 정보가전산업은 다양한 통신 기기와 통신이 가능하게 되었지만 각 가전기기들과의 통신이 많아지고 복잡해지고 있다 이런 기기들을 효과적으로 관리하고 기기 전체를 통합할 수 있는 홈네트워크 형태의 기술개발은 아직 진행 중에 있으며, 사용자에게 효과적인 QoS를 지원하기 위한 방법론의 고려가 부족한 실정이다. 그러므로 본 논문에서는QoS지원을 위해서 홈네트워크와 인터넷 기반의 policy-based network기술을 통합할 수 있는 미들웨어 서비스에 관하여 언급하였다.

본 논문은 인터넷과 같은 다중제공자(multi-provider) 네트워크 환경 하에서 패킷 플로우를 효과적으로 제어하기 위한 SDN(Software Defined Networking) 기반의 정책 제어기를 소개한다. 제안된 정책 제어기는 네트워크 가시성 정보를 이용해 가상링크 및 가상포트 등을 직관적으로 제어함으로써 효과적인 서비스 오버레이 네트워킹(service overlay networking) 환경을 실현한다. 또한, 논리적으로 구분된 다수의 주문형 가상망을 신속히 구성하고 동적으로 관리함으로써 응용에 최적화된 네트워킹 환경을 사용자에게 제공한다. 본 논문에서는 정책 제어기의 구조 및 특징을 소개한 후, 멀티캐스트를 위한 두 가지 서비스 응용을 예시한다. 또한, 해당 응용들을 이용한 네트워크 서비스의 구성 시간을 성능 평가함으로써 정책 제어기의 적용 가능성을 확인한다.

With increasing globalization, a proper policy for global inter-city networking strongly required, which presumes the study on the heterogeneity among regional innovation systems. While surveying the research results of the Evolutionary Economics, 1 stress that regional systems of innovation differ in technological capacities, industrial structures, institutional arrangements and socio-cultural features. 1 make the empirical investigation based on the data of Busan and Hamburg, making clear the regional specificities among regional innovation systems. The results show that regional systems of innovation in Busan and Hamburg are quitely asymmetric. They suggest also the limitation of neo-classical assumption on the ‘homogeneous production function’ and that policy-makers in regions should make the policy for ‘global inter-cities networking’, based on perspectives of regional heterogeneity.

Recent entrepreneurship studies emphasize the importance of entrepreneurial activities of entrepreneurs. This study focuses entrepreneurial behaviors, especially entrepreneurial networking activities of Korean high-tech ventures. Networking activities can utilize external resources which are critical to success, with less resource commitment. This study examines the relationship between characteristics of entrepreneurial networking and performance, and analyses influencing factors of entrepreneurial networking activities. Based on the data from 55 new high-tech ventures in Korea, hypotheses that the characteristics of entrepreneurial networking are related to the performance of new high-tech ventures are tested using regression analysis and t-test. Major findings of this study are as follows: (1) entrepreneurial networking are related to the performance of new high-tech ventures, (2) significant differences are found in the characteristics of entrepreneurial networking between high- and low-performance firms, (3) characteristics of entrepreneurs and firm' technological capabilities are related to the degree of entrepreneurial networking activities. Finally, managerial and policy implications of the study are presented and future research directions are also suggested.

With an increase in the relevance of next-generation integrated networking environments, the need to effectively utilize advanced networking techniques also increases. Specifically, integrating Software-Defined Networking (SDN) with Multi-access Edge Computing (MEC) is critical for enhancing network flexibility and addressing challenges such as security vulnerabilities and complex network management. SDN enhances operational flexibility by separating the control and data planes, introducing management complexities. This paper proposes a reinforcement learning-based network path optimization strategy within SDN environments to maximize performance, minimize latency, and optimize resource usage in MEC settings. The proposed Enhanced Proximal Policy Optimization (PPO)-based scheme effectively selects optimal routing paths in dynamic conditions, reducing average delay times to about 60 ms and lowering energy consumption. As the proposed method outperforms conventional schemes, it poses significant practical applications.

Recently, the COVID 19 pandemic has affected on our daily lives and society in many ways. Specifically, it has brought rapid changes in the working environment from office working to smart telecommuting. In addition, cloud computing technology and services not only provided ubiquitous access, but also led to a sharing of information, internal-external communication channels, telework, and innovative smart work for the business process. As a result, smart work services based on social cloud networking have spread to the public sector. However, existing academic research examining smart work merely remains to focus on the theoretical conceptualization or to deal with merely several examples of private views. Best practices of smart work services based on cloud computing technology in the public field rarely exists. Moreover, many studies have been differently measured the values of smart work for private and public sectors depending on organizational singularities. Therefore, the study aims to define new theoretical implications and to explore future business strategies and policy directions based on a technical working group's personal psychological subjectivity. The research applied Q methodology, and selected five public organizations in Korea, that they have adopted or currently plan to adopt some part of smart work services.

본 연구는 도시경제발전을 위한 국가 및 지방정책의 맥락에서 중소기업 네트워킹 정책을 활성화시키는 데 있어서의 한계점들을 대구지역의 사례를 중심으로 살펴보았다. 대구시와 같은 대도시에서는 도시경제의 이점을 활용하여 중소기업의 네트워킹 활동을 촉진시키는 전략은 지식기반경제에서 도시경제발전을 위해 필요한 것으로 보인다. 하지만, 기업유치라는 외생적 전략에 의존하는 국가 및 지방의 정책방향과 함께 지방과학기술정책이 중앙정부 주도로 추진되면서 중소기업보다는 대학과 연구소 중심으로 진행되고 있기 때문에 중소기업의 네트워킹 활동을 지원하는 정책을 제고하는 것은 어려운 것으로 보인다. 이러한 환경에서는 중소기업 네트워킹 활동 지원과 관련된 지역 특화 정책들은 소홀하게 다루어질 가능성이 높다.

Purpose - Based on the analysis of Kazakhstan's experience of digital transformation, this study suggests a concept for digital solution to optimize organizational process, create trust networking between the center of state scholarships programs and recipients. In addition, the authors contribute to the current discussions of an effective digital transformation of state services. Research design, data, and methodology - Policy analysis is based on the combination of both primary and secondary materials collected during a Policy Research Project conducted in Kazakhstan in 2017. It involved semi-structured interviews with the state scholarship' recipients, ICT experts and findings from academic articles. Results - Findings are represented via Policy Development Matrix - a table with three options (status quo, partial change, total change) to deal with policy challenges. Authors suggest a concept for digital solution following the Customer Relationship Management (CRM) principles for optimizing core business processes, communication and networking strategies of the state scholarships program. Conclusions - At the time when digitalization becomes trending for states, the transformation of the state education policy is inevitable. The rapid development of digital technologies creates new opportunities for a single integration platform with key principles of Smart Remote Management in the state scholarships programs.
