    摘要： Disclosed is an overlay multicast system for a group media transmission application service composed of a multiple stream, wherein, when an additional stream is newly transferred to a predetermined node in an overlay network, the overlay multicast system transmitting a plurality of streams in the overlay network generates a multiple stream by muxing a main stream inputted from a parent node and the additional stream based on stream correlation information in the predetermined node, and transmits the generated multiple stream to a child node.

    摘要： A multi-function optical measurement device having an optical wavelength and power measurement function, a ferrule/fiber scoping function, and a ferrule/fiber cleaning function includes a path select unit separating an optical signal for transmission and an optical signal for scoping from a ferrule/fiber; a wavelength and power measurement unit measuring a wavelength and a power of the optical signal for transmission from the path select unit; and a ferrule/fiber scoping unit converting an optical signal for scoping from the path select unit into an electrical signal. It is possible to perform a wavelength and power measurement and a ferrule/fiber scoping by one connection. Since a ferrule/fiber cleaning may be additionally included in one measurement device, it is easy to handle and carry an optical measurement device. A time required to perform a work using an optical measurement device may be reduced.
