摘要： A motion image( MPEG II) video stream transmission system for transferring MPEG II video stream to a subscriber by receiving 6 channels of a motion image(MPEG II) video stream, and includes: a MPEG II encoder for encoding an analog video signal on a motion image video signal; a framer for framing and outputting a MPEG II video stream by controlling a read clock of pure data of the MPEG II video stream whenever data is variable, registering a transmission velocity information to a video stream inputted in the MPEG II encoder; a first multiplexing means; a second-stage multiplexer; a headend having an optical transmission means; an optical transmission system; a first-stage demultiplexing means; a second-stage demultiplexing means; a remote terminal having a video switching system; and a subscriber terminal apparatus for converting the MPEG II video signal into an analog signal after reframing a video signal outputted from the remote terminal and outputting the converted signal.

摘要： An apparatus for processing packets in a high speed router and a method thereof are provided. The high speed router includes a forward processor and a control processor where the forward processor having an input terminal processor and an output terminal processor. The output terminal processor manages a Layer 2 Address Table by dividing the Layer 2 Address Table into a layer 2 indirect address table and a layer 2 direct address table and by managing them. The indirect address table is directly indexed in the Next-hop Table of the input terminal processor table. The direct address table is composed of a hashing table for a destination IP address. Therefore, the system efficiency can be improved by reducing the memory which is used for storing the forwarding information table occupied by the forward processor and by reducing the IPC message between the control processor and the forwarding process.
