Military communications have limited resources such as poor bandwidth and insufficient link capacity. Numerous hosts in conventional IP networks, including the Tactical Information Communication Network (TICN), the tactical communication system of the Army, focus heavy traffic on a single server via end-to-end connections and in which data delivery latency is caused by exchanging routing information. Content-Centric Networking (CCN), one framework of Information-Centric Networking (ICN), is a novel Internet paradigm in which data can be accessed by the name of the content instead of the location information. This paper provides content caching strategies for applying CCN to military tactical IP networks based on TICN environment.

Information Centric Networking that uses content name instead of IP address as routing identifier can handle challenges such as traffic explosion and user mobility, but it also suffers from scalability and incompatibility problems. In this paper by combining the concept of software defined networking and Internet end to end arguments, we propose a wide area deployable software defined information centric networking service model named SD-ICN. SD-ICN employs a dual space structure that separates edge service network and core transmission network. The enhanced SDN techniques are used in edge service network in order to implement intelligent data routing and caching, while traditional IP technique is reserved in core transmission network so as to provide wide area high speed data transmission. Besides, a distributed name resolution system based on the cooperation of different controllers is also presented. The prototype experiments in our campus network show that SD-ICN can be deployed in a scalable and incremental way with no modification of the core network, and can support typical communication modes such as multicast, mobility, multihoming, load balancing, and multipath data transmission effectively.

As individuals create many contents anytime and anywhere together with the widespread dissemination of smart devices as well as various social networking services (SNS), content centric networking (CCN) has regarded as a new networking technology. However, CCN is exposed to malicious attacks on the mobility management of mobile content sources during handover and high volume of control messages. Therefore, this paper presents a secure duplicate name detection (SecureDND) mechanism without additional control messages by signed information and secure token. It is shown from the performance evaluation that the proposed scheme can provide low control overhead, which results in the network scalability.

This paper presents a secure and DoS-resistant fragment authentication technique for Content-Centric Networking (CCN). Our approach not only guarantees the authenticity of each fragment, but also provides a high resistance to DoS attacks through the immediate verification of fragment authenticity at interim nodes on the routing path. Our experimental results demonstrate that the proposed approach provides much stronger security than the existing approach, without imposing a significant overhead.

Wireless communication offers the flexibility to the node movement at the spatial dimension more than the wire communication not only in IP architecture but also in Content-Centric Networking. Although it gives such advantage, the intra-domain movement of a node especially the data source node affects the communication to the access point node which in the end affects the acceptance ratio of the client node that requests the data packets from the data source node. In this paper, we use time-division access method to maintain the acceptance ratio of the client node as the effect of the intra-domain data source node movement in Content-Centric Networking. The simulation result shows that the acceptance ratio of the client node can be maintained using the time-division access method as long as the interval access time is less than the coherence time.

Recently, Information-Centric Networking(ICN), different from traditional IP-based networking, has been highlighted. Content-Centric Networking(CCN), proposed by Van Jacobson, is a representative scheme of the ICN architectures. It can deliver messages slightly faster than the IP-based networking by focusing on the access and delivery to the content itself. However, CCN is restricted to distribute the information without transmitting the request packet in advance because it is pull-based architecture by content requester. In addition, it has a problem that the Pending Interest Table(PIT) could be overloaded easily when DDoS attack happens. In this paper, we suggest an algorithm using a push-based scheme without request packets and overcoming PIT overload situation by Interest Group Push Table(IGPT). The proposed scheme enables to transmit a large amount of content than an existing scheme during the same amount of time in terms of timely-delivery and security.

Due to an explosive growth in services running in different datacenters, there is need for service selection and routing to deliver user requests to the best service instance. In current solutions, it is generally the client that must first select a datacenter to forward the request to before an internal load-balancer of the selected datacenter can select the optimal instance. An optimal selection requires knowledge of both network and server characteristics, making clients less suitable to make this decision. Information-Centric Networking (ICN) research solved a similar selection problem for static data retrieval by integrating content delivery as a native network feature. We address the selection problem for services by extending the ICN-principles for services. In this paper we present Queue and Latency, a network-driven service selection algorithm which maps user demand to service instances, taking into account both network and server metrics. To reduce the size of service router forwarding tables, we present a statistical method to approximate an optimal load distribution with minimized router state required. Simulation results show that our statistical routing approach approximates the average system response time of source-based routing with minimized state in forwarding tables.

In this paper, I have measured NCO(Network Centric Operation) Effectiveness of Anti-piracy Operation at the Chunghae Unit. For quantitative analysis, Network Centric Operations Conceptual Framework(U.S Office of Force Transformation) is applied. In accordance with the framework, the Chunghae unit anti-piracy operation scenario is analysed. The scenario is devided with two case(only voice communication and networking). The element of analysis be composed of the organic information, networking, share-ability, and individual information. As a result of analysis, the individual information of first case(only voice) gets 0.59 points. The other side, second case (networking) gets 1 points. This means that NCO has effect on the Chunghae Unit's mission. In addition, I stated the tactics advantage of NCO related a fighting power.

Information-Centric Networking (ICN) has been recognized as a new networking technology for the upcoming data-centric 4th industrial revolution based society. In addition, it has noted that Pub/Sub-style communication is rapidly growing in areas including big data processing and microservice as well as the existing Internet of Things and social networking technologies. Therefore, ICN is highly needed to efficiently support Pub/Sub-style communication for successful deployment as a next-generation network infrastructure technology. This paper summarizes the recent research trends of Pub/Sub communication technologies over ICN, and discusses future research issues.

As users generate lots of contents anytime and anywhere with an explosive growth of the number of mobile devices, Content centric networking (CCN) has emerged as a new networking architecture. However, the efficient CCN routing scheme is required for ad hoc network support because of its one to one message exchange characteristics. So, this paper proposes the new CCN ad hoc routing scheme using on-demand approach, which includes the secure routing configuration scheme based on multiple hash operation. It is shown from the simulation that the proposed method can provide lower control overhead because of its two-fold routing configuration architecture.
