  • Broadband switching networks
    Patent number: 6985487
    Abstract: Broadband switching networks are disclosed, which has a plurality of broadband switch nodes and a broadband switch inter-node transmission line for connecting the plurality of broadband switch nodes, information being transmitted by cells, each of which comprises a header and an information field, wherein the broadband switch node comprises a broadband input and output port for inputting and outputting the cells to and from the broadband inter-node transmission line, and a switch for separating the cells being input through the broadband input and output port and for multiplexing the cells so as to output them, wherein data composed of the plurality of cells is transmitted and received through the broadband switch node by constant bit rate transmission, variable bit rate transmission, or a combination of the constant bit rate transmission and the variable bit rate transmission.
