Data Naming has been a long-lived issue in data management. A data name is a basic vehicle to convey meanings of data. Thus, names are organized in such a way that anyone can understand their meanings with ease; however, Korean data names have been organized based on English-like naming scheme. This paper proposes a Korean data naming scheme. For this, we specify information that data names should include. Secondly, we propose rules to organize data names. For real world applications, a database system is proposed to manage data names. The database is expected to provide a starting point that on organization can develop its own data name repository.

If the topology changes in the re-generation step of the history-based and feature-based CAD systems, it is difficult to identify an entity in the old model and find the same entity in the new model. This problem is known as 'persistent naming problem'. To exchange parametric CAD models, the persistent naming problem and the naming mapping problem must be solved among different CAD system, which use different naming scheme. For CAD model exchange the persistent naming has its own characteristics compare to that for CAD system development. This paper analyses previous researches and proposes a solution to the persistent naming problem for CAD model exchanges and to the naming mapping problem among different naming schemes.

Recent, Cyber attacks such as hacking and malicious code techniques are evolving very rapidly changing cyber a ttacks are increasing, the number of malicious code techniques vary accordingly become intelligent. In the case of m alware because of the ambiguity in the number of malware have increased rapidly by name or classified as maliciou s code may have difficulty coping with. This paper investigated the naming convention of the vaccine manufacturer s in Korea to solve this problem, the analysis and offers a naming convention for security control event detection r ule analysis to compare the pattern of the detection rule out based on this current.

Content-centric networking (CCN) is a future Internet technology to reorganize the paradigm of end-to-end communication of the current IP-based Internet architecture into a content-based paradigm. In managing such new networks, the network management is one of the most important functions. The standard for typical network management in existing IP networks is Simple Network Management Protocol (SNMP). Though there have been several works to implement network management functions on CCN, they have their own limitations to apply them to pure CCN operational environments. The basic reason of the limitation is that existing methods operate in an IP-overlay structure, or do not support push-type information exchange. In this paper, we propose a new naming structure that can accommodate both pull and push-type SNMP methods for CCN network management with SNMP. Then, methods to support GET and TRAP methods as well as a SET method of SNMP in the pure CCN environment using the proposed naming structure are proposed. We implement the proposed method using CCNx, and construct a CCN network testbed to validate the effectiveness of the proposed method by monitoring appropriate exchange of SNMP messages over the testbed.

Content centric networking (CCN) is regarded as promising internet architecture because it can provide network efficiency in terms of bandwidth consumption by separating contents from a specific network location and decrease network congestion events. However, the application of a CCN does not widely consider the side effects of mobile devices, particularly mobile content sources. For content source mobility, a full routing update is required. Therefore, in this study, a route optimization scheme is proposed for mobile content sources in a CCN environment to provide low communication overhead, short download time, and low resource consumption. The proposed scheme establishes a direct path between content requesters and a mobile content source for the exchange of interest and data packets using interest-piggybacked data packets. Based on the inherent CCN naming characteristics, the content source does not know the name prefix of the content consumer, and thus the proposed optimized CCN scheme utilizes the content router in the home domain of the content source.

IP header compression schemes offer a valuable measure for bandwidth preservation. Such schemes have been practically implemented in infrastructure-based IP networks for point-to-point links. However, minimal research and practical implementation efforts have been conducted in the direction of an IP header compression strategy that can meet the peculiar requirements of multi-hop ad hoc wireless networks. In this paper, we present a practically implemented multi-hop IP header compression scheme using the Robust Header Compression (ROHC) protocol suite. The scheme runs on a novel identifier (ID) based networking architecture, known as an ID-based ad hoc network (IDHOCNET). IDHOCNET additionally solves a number of bottlenecks of pure IP-based ad hoc networks that have emerged owing to IP address auto-configuration service, distributed naming and name resolution, and the role of an IP address as an identifier at the application layer. The proposed scheme was tested on a multi-hop test bed. The results show that the implemented scheme has better gain and requires only O (1) ROHC contexts.

NAPRT(Naming Authority Pointer) is a type of resource record specified in IETF RFC 2915. NAPTR enables to register various services in the Domain Name Systems and thus provides a way to discover services available on specific hosts. This paper describes the design and implementation of a Proxy DNS system aimed at supporting NAPTRs. The goal of this work is to study on the feasibility of the service discovery registered in DNS via NAPTR records and provides the result for simplicity and extensibility of implementation through the implementation of a actual Test-bed system This research result can be applied to service discovery in the resource information management for high performance GRE environments as well as to the implementation of DNS infrastructure for the ENUM.

This paper describes implementation of the core DSM-CC UU interface. It briefly describes the reference model for the DSM-CC and related standards that should be reviewed for the implementation. The Common Object Request Broker Architechture, Revision 2.0 (CORBA 2.0) is sued as a remote procedure call (RPC) scheme for the UU Interface. Entire system was implemented with C++ on Windows NT platforms. The implementation procedure has been decomposed ito two tasks. The first task is to implement the Naming Service for service navigation. The Naming Service is one of the CORBA Services that extend the core CORBA specification. A client GUI is implemented for easy navigation among various services. The second task is to construct multimedia server and client for a Video-on-Demand (VoD) system. MPEG-2 Transport Stream is transported via ATM AAL5 using the Windows Socket 2.2 ATM extension API. A GUI enables the user to navigate the service domain and select a program. After the selection the user can control the MPEG-2 stream with VCR-like buttons.

The access to web applications has continuously evolved toward the adoption of content centric interfaces. Services and information items are much of user's concern than web sites. For an efficient accommodation of increasing needs of content oriented operations, the scope of domain names is extended in two directions. A naming scheme is derived that is suitable for resource level access units and the semantics of domain names is conceived as very flexible functions. First extension regards the removal of unnecessary TLD's of domain names for resource level binding. Second extension makes the resource level domain names rich in functional binding and consequently various applications can be directly triggered by the invocation of domain names without intervening medium. These extensions may lay a certain direction for the future internet evolution.

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.
