  • An Ethernet PON(Passive Optical Network) is an economical and efficient access network that has received significant research attention in recent years. A MAC(Media Access Control) protocol of PON , the next generation access network, is based on TDMA(Time Division Multiple Access) basically and can classify this protocol into a fixed length slot assignment method suitable for leased line supporting QoS(Quality of Service) and a variable length slot assignment method suitable for LAN/MAN with the best effort. For analyzing the performance of these protocols, we design an Ethernet PON model using OPNET tool. To establish the maximum efficiency of a network, we verify a MAC protocol and determine the optimal number of ONUs(Optical Network Unit) that can be accepted by one OLT(Optical Line Terminal) and propose the suitable buffer size of ONU based on analyzing the end-to-end Ethernet delay, queuing delay, throughput, and utilization.

  • This paper presents an Interprocessor Communication Network(IPC net) in ATM switching system. In order to supply stable and independent path for processor communication, additional network i.e., Ethernet, is suggested. An Ethernet switch centered on Ethernet binds each processor into a work range. IPC net proposed in this paper assures end-to-end inter-processor connection, uniform 100Mbps Ethernet bandwidth and enhanced user cell throughput of ATM switch with minimum Ethernet supporting block integrated into ATM system

  • Gigabit Ethernet was advented as Internet's activation from owing to Internet user and the development of its various application and as inevitability the high-speed network as its demand for more and more the bandwidth by much application using the network. This Gigabit Ethernet makes an alternative plan to solve the request traffic by Internet user, because it holds several merits as providing great capacity with the network in the existing Ethernet environment and as displaying highly efficient ability This paper researches into a concept and characters about Gigabit Ethernet technology and raises the stability and efficiency of Gigabit Ethernet with regard of competing against FDDI technology and using Traffic analysis.

  • This paper deals with the design and implementation of an Ethernet-based communication protocol to be used in PC-based I/O interface systems. Recently, the performance of PC systems is being highly improved and Ethernet is used as the stable communication network over the world. We develop a new protocol driver with the capability of accessing Ethernet directly using NDIS(Network Driver Interface Specification), the network interface standard of Windows O.S. in PC, and install it at the application layer of the protocol structure. Its major roles are the supplement of CSMA/CD algorithm, the effective use of the long data frame of Ethernet, and the real-time transmission of data frames. This paper represents the possibility of the real-time control network and systems based on PCs and Ethernet.

  • 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.

  • In the multimedia age, the development of Internet/Intranet circumstances makes Required Traffic per user be gradually larger. And the more demand getting many pieces of information quickly increases, the more required the rapid network is as a necessary consequence. This is why we need the advanced Ethernet. Gigabit Ethernet has many advantages in many respects. For example, it increases the capacity of network and makes network highly efficient in the existing Ethernet circumstance. Thus, Gigabit Ethernet becomes a counterproposal that can resolve Required Traffic per internet user. Present study inquires the concepts and the characteristics connected with Gigabit Ethernet Technology and analyses the Link efficiency with a hypothetical modeling.
