The vehicle network such as CAN, MOST, Ethernet has different protocols. In the case of Ethernet data, when data is transmitted from Ethernet to MOST150, it cannot be treated by Ethernet channel of MOST150, leading to data loss and transmission delays. Thus, this thesis proposes vehicle integration GATEWAY, which can form a network by organically connecting the Ethernet and MOST150 networks and minimize the delay and data losses caused by the differences in bandwidth.

As demands increase for the Infotainment System, the Multimedia Networking technology for automobile, called MOST(Media Oriented Systems Transport), has been actively applied to the automobile industry, to meet the demands of the Infotainment System. The MOST25 network technology is being restrictively equipped with some of the car models but the problems withbandwidth and compatibility has arisen. In order to solve this, the MOST150 technology has been developed and further research is being carried out to applythe technology to the automobile industry. Thus, for the effective process of the Ethernet traffic in the realization of MOST150/Ethernet Gateway for automobile, we, in the research, shall analyse the Management Mapping method, including the MOST150's Isochronous channel, the MOST Ethernet Packet Channel, and etc. and study the efficient algorithm.

MOST150, which has a higher bandwidth than of MOST25, appears to satisfy the demand for the automotive infotainment system and to increase the multimedia processing capacity, and the various technology applications are required for the accomplishment of MOST150 development. The MOST25 network technology is being restrictively equipped with some of the car models but the problems with bandwidth and compatibility has arisen. In order to solve this, the MOST150 technology has been developed and further research is being carried out to apply the technology to the automobile industry.

The application of MOST150 technology has been required to satisfy the demand for the automotive infotainment system and the higher bandwidth requirements caused by the increase of the multimedia processing capacity. The Ethernet technology applied gateway was implemented for an efficient transmission of multimedia, a vehicle diagnosis, an external communication, a data processing between the MOST150 and the CAN communication method applied to many existing vehicles. The new algorithm and application were suggested in order to efficiently perform the data processing between other types of communication systems. The existing MOST150 frame is mainly composed of the Control Channel, the Legacy Packet Channel(async) and the Synchronous /Isochronous Channels and performs the data processing through these sequential channels. With the sense of this process, this study suggested the new algorithm that the Mapping method of the IETF's QoS Management was applied to the MOST150 technology for the efficient QoS.

최근 지능형 자동차에 대한 연구가 활발하게 진행되면서 차량용 네트워크에 대한 관심이 증대되고 있다. MOST(Media Oriented Systems Transport)는 차량 내 멀티미디어 장치들이 증가함에 따라 다양한 장치를 하나의 광 네트워크로 연결하여 차체의 무게를 줄이고 단일 프로토콜을 이용하여 동기 및 비동기 데이터를 비롯한 다양한 제어 정보를 동시에 전달 할 수 있는 차량용 네트워크이다. 본 연구에서는 공용적인 Ethernet 네트워크와 MOST 네트워크간의 상호 제어 데이터 교환을 위한 시뮬레이터를 설계하고 이를 구현하는 것에 대한 연구이다.

This paper describes a gateway system based on a MOST network for integrating several different automotive network protocols. For transparent data communication among different protocols regardless of the high-level messages and the data format, Pseudo MOST frame was designed based on MOST frame and this pseudo MOST data frame is used as the data carrier. For automotive application, two types of gateways were developed, one board-type gateway and small-sized module-type gateways. One board-type gateway has ethernet port, video port and audio port. Meanwhile, small-sized module-type gateways are developed for video, audio, bluetooth and Flexray, respectively. Experiments with a network system using several small-sized module gateways verified efficient data communication among different network protocols and confirmed the effectiveness of the proposed gateway system for automotive network integration.
