  • MAP(Manufacturing Automation Protocol), Network Protocol for FA has 7 Layer Structure of OSI. Being an Application Layer Protocol for Communication Interfaced with the Actual Programmable Devices, MMS(Manufacturing Message Specification) Consists of Three Factors of Services, Interfaces, and Protocol. For Details, It Classifies with the Followings ; Connection/Context Management, Remote Variable Access, Semaphore Management, File transfer and Management, Program UP/DOWN Load, Remote Program Fxecution. In this Paper Designing MAP Network Station of Programmable Device, we Analyze the Protocol of MMS, and Realize the State Diagram of each Services and Propose the Model of MMS Function Call Instructions.

  • In this paper, we describe an IMT-2000 system architecture, a protocol stack, and basic MAP scenarios(e.g., registration, call delivery) based on the IS-41 and IS-41 and IS-751. This paper focuses on the MAP scenarios to support the IMSI which is defined for the global roaming between GSM and IS-41 Networks through the Family of System approach. This paper also deals with the design of the MAP protocol stack transported over the ATM networks and introduces the software structure of MAP in IMT-2000 MSC.

  • DOCSIS 3.0 MAC protocol regulate CM and CMTS Channel transfer times through MAP message. Standards does not include the details of MAP Inter-arrival Time affecting the performance of MAC protocols for DOCSIS 3.0. In this paper, we evaluationed the performance of protocol follow in MAP Inter-arrival Time on DOCSIS 3.0. Based on the evaluation results, we propose the optimal MAP Inter-arrival Time. We found that the protocol shows best performance when the MAP Inter-arrival Time is 0.05sec. The research results can apply to performance element which important for the construction of DOCSIS 3.0 base cable networks.

  • DOCSIS 3.0 protocol are proposed to support high-speed cable network DOCSIS 3.0 MAC protocol regulates CM and CMTS channel transfer times through MAP message. So MAP Inter-arrival time is primary factor of network performance. However, standards does not include the details of MAP Inter-arrival Time affecting the performance of MAC protocols for DOCSIS 3.0. In this paper, we evaluated the performance of DOCSIS 3.0 protocol follow in MAP Inter-arrival Time. Based on the evaluation results, we propose the optimal MAP Inter-arrival Time. We found that the protocol shows best performance when the MAP Inter-arrival Time is 0.05sec. The research results can apply to performance element which important for the construction of DOCSIS 3.0 base cable networks.

  • IETF 에서는 이동노드와 다른 엔티티들 사이에서 발생하는 시그널링을 줄이기 위하여 계층적 이동성 관리 프로토콜(HMIPv6)을 제시하고 있다. HMIPv6는 MAP이라는 새로운 엔티티를 도입하여 특정 지역 내에서 지역 흠 에이전트의 역할을 수행하도록 함으로써 이동노드와 다른 엔티티 간에 발생하는 시그널링을 줄이고, Mobile IPv6의 핸드오프 성능을 개선하도록 하고 있다. HMIPv6에서는 MAP과 이동노드 사이의 인증을 위해 IKE 와 같은 보안 프로토콜을 사용하도록 정의하고 있다. 본 논문에서는 많은 부하가 걸리는 IKE 대신에 RR(Return Routability) 절차를 이용하여 이동노드와 MAP 사이의 인중을 제공하는 방법을 제안한다.

  • In this paper, we define two security concepts, “non-computable security” and “distribution security”, about authentication information committed to a authentication server without any trustee, and propose an authenticatied key exchange protocol based on password, satisfying “distribution security”. We call it MAP(Muti-Server Authentication Protocol based on Password) and show that SSSO(Secure Single Sign On) using MAP solves a problem of SSO(Single Sign On) using authentication protocol based on password with a trustee.

  • This study aims to develop the Vehicle Local Dynamic Map (V-LDM) and demonstrate its performance for providing dynamic map data efficiently to the vehicle control module. Firstly, the concept of the in-vehicle LDM has been established and then the system has been carefully designed according to the international standards. The high-precision digital map embedded in LDM has been designed to incorporate the lane-level information of road network, and the Dynamic Map protocol (DM protocol) which is a message protocol including the road data with dynamic traffic event data has been defined. The performance test of the proposed system has been conducted in the uninterrupted road section of Kyungbu expressway, showing that both of the data size and the elapsed time to finish the process are almost linearly proportional to the length of target road. Finally, it is recommended that the length of target road for DM protocol be less than 250m.

  • Hierarchical Prefix Delegation (HPD) protocol refers to a type of solution to problems inherent in non-optimal routing which occurs with Network Mobility (NEMO) basic solution. However, because HPD cannot improve the micro-mobility Problems, Problem surfaces each time Mobile Network Node (MNN) changes the attachment point; as happens also in a Mobile IPv6 (MIPv6) protocol in sen야ng Binding Update (BU) messages to Home Agent (HA) / Correspondent Nodes(CNs) By applying Hierarchical Mobile IPv6 protocol concept to HPD, this study Proposes an algorithm for effectively handling micro-mobility problems which occur with HPD in a nested NEMO environment. By sending BU only to nearby Mobility Anchor Point(MAP) during MNN location change within a MAP's domain, the proposed protocol will alleviate service disruption delays and signaling loads during the handover process, overcoming the limitations of HPD.
