Recently, there is a growing interest in the 4th revolution called 'fusion and connection', and 'high connectivity society' is in sight. As a result, interest in the Internet of things has reached a record high, and it is not limited to automation and connected cars. Therefore, the Internet of things is expected to play an important role in building ecosystem of next generation mobile communication service. So, in this paper, we will introduce what kind of mobile communication is suitable for internet of things and the technology trend of internet communication for Internet of things.

Metabus, currently represented by Second Life on the Internet, is the next-generation 3DCG Internet world in which the 2D Internet world has evolved, and has grown as a new ICT culture of mankind that can replace real society with virtual society. As such, the reason why the world of metabus has rapidly expanded is that the era of 3D Internet has arrived due to the evolution of the Internet, which only used information, and the spread of 5G communication in user-participating WEB. However, there are many situations in which laws do not exist in this virtual world and various illegal acts occur. As the Internet culture developed earlier, illegal activities by users began to appear, and as the legal responsibility of Internet providers was discussed, mankind quickly passed the Millennium Copyright Act or introduced new copyright protection measures such as technical protection, transmission rights, and rights management information. Therefore, this paper reviews and studies how to accept and further grow this new metabus culture, including the viewpoint of intellectual property.

Home appliance manufacturers have recently been trying to provide smart products capable of various Internet services. For example, one health care manufacturer provides a Wi-Fi-capable scale. Once users register their information with the manufacturer's server, their weight and body fat records are automatically uploaded to the server whenever they measure their weight. The users can then watch and check their weight log easily using a smart device, such as a smartphone or tablet. One of the biggest problems, however, is that the initial configuration of the appliances and the user registration process may be quite complicated to typical users who are unfamiliar with such IT devices. This paper proposes an autoconfiguration system structure and protocol for Internet-capable home appliances, which supports the initial configuration and remote maintenance service of the device with only little user effort. Manufacturers can develop their own information appliances and provide differentiated services using the proposed system and protocol.

As smartphone users grow, mobile operators are trying to standardize and commercialize Rich Communication Suite (RCS), which is a next-generation messaging service, so that it can replace legacy messaging services. However, it is not enough to spread RCS widely to the users only by publishing an RCS app. To increase the use of RCS, a web-based open API for common RCS capabilities is needed. By using the API, Internet-based developers can create applications that make use of the RCS capabilities with less effort and time. This paper proposes a lightweight Comet-based open API to allow mobile operators to expose useful information and capabilities to application developers. The system architecture of the open API framework and call flow between relevant nodes are defined. In addition, examples of protocol translations on the framework are provided.

Named data networking (NDN) is a new network architecture designed for next generation Internet. Router-side content caching is one of the key features in NDN, which can reduce redundant transmission, accelerate content distribution and alleviate congestion. However, several security problems are introduced as well. One important security risk is cache privacy leakage. By measuring the content retrieve time, adversary can infer its neighbor users' hobby for privacy content. Focusing on this problem, we propose a cache privacy protection mechanism (named as CPPM-DAM) to identify legitimate user and adversary using Bloom filter. An optimization for storage cost is further provided to make this mechanism more practical. The simulation results of ndnSIM show that CPPM-DAM can effectively protect cache privacy.

DWDM(Dense Wavelength Division Multiplexing) 기반의 광 네트워크가 범 세계적인 차세대 광 인터넷(NGOI: Next Generation Optical Internet) 백본망의 대안으로 인식되고 있으나, 기존의 전기적인 오버헤드 비트를 이용한 전송 관리 정보의 사용이 더 이상 유효하지 않아 장애 관리에 많은 문제점을 드러내고 있다. 본 논문에서는 NGOI 백본망의 링크 관리를 위해 광 성능 모니터링 시스템 및. GMPLS(Generalized Multi-Protocol Label Switching)의 링크 관리 프로토콜(LMP: Link Management Protocol)을 활용한 관리 모델을 제시한다.

This paper highlights new IP network design and internetworking scenarios overlayed on the existing ATM technology network. It describes the proper network configurations to solve the IP/ATM internetworking probrems on the AISN(Advanced Information Superhighway Network). The paper outlines that IP network can be constructed on ATM backbone network. The paper looks at how new design technology is to enhance the AISN in Korea. The paper concludes that new IP network design is applied to AISN and there is enough possibility that AISN can be developed to efficient NGI(Next Generation Internet).

IPv6 that is next generation internet was appeared because of the shortage of IPv4 address. In present, there has been studying about the home networking which allocates IPv6 address to home appliances. In this paper, It makes 16bits unicast address using remainder 4bits after making 124bits address using 64bits prefix address of IPv6 and 60bits having the form of E.164 proposed RFC2916, IETF and implemented and designed the home networking communicating home appliances having unique unicast address

The requirements for the high quality service is increased according to the changing of the internal environment. But, the computer system can not satisfy the requirement because of the limitation of the computer's own problem. This paper describes the network storage accelerator which can perform the high quality streaming service. We also show the implementation result of the streaming accelerator.
