| 摘 要： | The advent of dense wavelength division multiplexing (DWDM) raises the raw bit rate in a single fiber from a few Gigabits per second (Gbps) to tens of Terabits per second (Tbps), and enables the total bit rate in a single fiber reaching the order of magnitude of Tera bits. This achievement opens a new era for high-speed networks, and potentially, enables existing telephone, cable TV, and computer networks to be merged into a unified network. However, in a merged network, service requiremen…

| Abstract: | A novel technique called physical frame time-slot switching (PFTS) is discussed and its technical and application aspects are analyzed. The format of the ethernet media access control (MAC) frame is borrowed in defining the physical frame for PFTS and the transmission time for the maximum size of the MAC frame is defined as a physical frame time-slot (PFT). Consequently, user data can be fed into PFTS and switched in a single layer sub-network in an asynchronous mode. |
