    摘要： A home network system for supporting continuity of data transfer destined for an MS (Mobile Station) when the MS moves between wireless nodes, comprising a server for storing multimedia data and a network connecting the server to the MS via the wireless nodes. A first wireless node, while transferring predetermined data from the server to the MS, senses that a connection with the MS is cut off. The predetermined data to be transferred to the MS is then buffered in one or more of the wireless nodes at a time point of disconnection with the MS, and the first wireless node maintains a connection with the server. A second wireless node in the home network system establishes a connection with the MS and, in response a data transfer request from the MS, provides the buffered data to the MS.

    摘要： A method for effectively implementing real time multimedia data transmission in an Ethernet network that operates in a CSMA/CD (Carrier Sense Multiple Access/Collision Detect) scheme. Real time data gets priority over general data, and uses an MPCP (Multi-Point Control Protocol) of the IEEE 802.3ah EPON to prevent a collision from occurring in real time data transmission, and also prevents delay time variation. An RT-IFG (Real Time Inter-Frame Gap) is defined for real time data, shorter than an IFG, to give priority to the real time data over general Ethernet data. The MPCP is used for transmission of real time data without collision between the real time data.

    摘要： A method and apparatus for transmitting data from an optical network unit (ONU) to an optical line termination (OLT) in a Gigabit Ethernet passive optical network (GE-PON) on the basis of a time division multiple access (TDMA) scheme are provided. A measurement of a data transmission time when the data is transmitted to the OLT is obtained, and the measured data transmission time is compared with a predetermined normal transmission time. The transmission of the data is maintained if the measured data transmission time is determined to be less than or equal to the normal transmission time from the comparison result. However, if the measured data transmission time is determined to be greater than the normal transmission time, the transmission of the data is stopped.
