<p>Stochastic Time Division Multiplexing (STOTDM) is disclosed. in STOTDM data packets are preceded by a flag word. Each data packet appears in a frame of data packets in a predetermined order. If there is no data to be placed in the packet location, only the flag is transmitted and the data location is allocated to other data. By using a fixed length frame, synchronous data packets can be placed near the beginning of the frame and packets which are not timing sensitive may follow them. A variable length frame may also be used wherein data from a plurality of sources are once again ordered and preceded by a flag word or bit. The flag may be used to indicate whether or not the packet location is filled or this may be determined by control packets. Variable length frames may be accommodated as long as the average bandwidth required to transmit the data does not exceed the channel bandwidth.</p> |
