Means and apparatus for a scaleable congestion free switching system with intelligent control III

摘要

A switching system for routing information packets that can simultaneously receive a variety of packet formats. The packet formats include electronic packet transmissions, optical wave division multiplexed data (WDM) with a single frame consisting of a plurality of packets to be sent to a common output line, with each packet traveling on a separate wavelength, WDM packets where the header of an individual packet travels on a wavelength different from the remainder of the packet (i.e. the payload) and the payload either travels on a single wavelength or is subdivided into a plurality of sub-packets with each sub-packet carried on a separate wavelength, and the like. The system includes input devices, a scheduling unit, a switching unit; and variable delay line units. A deconcentrator in the packet switching system creates a minimum gap between packets.
