The aspect of future warfare is NCW(Network Centric Warfare) in accordance with the IT development, so MND have the planning of M-BcN(Military Broadband convergence Network) establishment as the basic system of NCW by the end of 2008. IPv6 address must be managed systematically as a essential element of NCW. In the previous study, it is designed on the basis of the present military information communication network topology. However, it makes some problems. First, it is difficult for present topology to adapt the future M-BcN which is different from the present military network topology. Second, it has defects of inefficiency of route aggregation and enlargement of routing table size. In this paper, we improved the route aggregation and routing table size by assigning the hierarchical address on the basis of M-BcN topology and adjusting the position of field identifying service network. Furthermore, it is proved by the network simulation program(OPNET 12.0).

Recently, with the rapid development of video equipment and technology, tremendous video information is produced and utilized in military domain to acquire battlefield information or for effective command control. Note that the video playback devices currently used in the military domain ranges from low-performance tactical multi-functional terminals (TMFT) to high-performance video servers and the networks where the video information is transmitted also range from the low speed tactical information and communication network (TICN) to ultra-high speed defense broadband converged networks such as M-BcN. Therefore, there is a need for an efficient streaming technique that can efficiently transmit defense video information in heterogeneous communication equipment and network environments. To solve the problem, this paper proposes a Scalable Video Coding (SVC) and balanced selection algorithm based Peer-to-Peer (P2P) streaming technique and the feasibility of the proposed technique is verified by simulations. The simulation results based on our BitTorrent simulator show that the proposed balanced selection scheme outperforms the sequential or rarest selection algorithm.

The next generation mBcN should be built to cooperate with the wireless network to support hyper-speed and hyper-connectivity. In this paper, we propose a network architecture for the cooperation mBcN and 5G commercial network and architecture of the cooperative security gateway required for the cooperation. The proposed cooperative security gateway is between gNB and UPF to support LBO, SFC, and security. Our analysis shows that the proposed architecture has several advantages. First of all, user equipment connected with the mBcN can be easily connected through the 5G commercial radio network to the mBcN. Second, the military application traffic can be transmitted to mBcN without going through the 5G core network, reducing the end-to-end transmission delay without causing the traffic load on the 5G core network. In addition, the security level of the military application can effectively be maintained because the user equipment can be connected to the cooperative security gateway, and the traffic generated by the user equipment is transmitted to the mBcN without going through the 5G core network. Finally, we demonstrate that LBO, SFC, and security modules are essential functions of the proposed gateway in the 5G test-bed environment.

Development of IT technology as well as arrival of information-oriented society raise the curtain of 'the era of Ubiquitous Computing', implying accessing computers beyond boundary of time and space. In this era, it is expected that IT paradigms and life-styles would be transformed immensely above the experiences of 20th century. However, improvement of technology summons a new risk of cyber terrorism which have not been in the past. Thus, it is urgent to prepare for the threats in the national level. This paper point out five major threats relating to 'the security in the era of Ubiquitous Computing'. : First, spread of threats in connection with BcN establishment, second, vulnerable information-security for wireless communication, third, leakage of private information, fourth, cyber terror and deterioration of security, fifth, security problems of Korea including the drain of military information and solutions in the views of organization, personnel, technology and budget, comparing with other countries.
