Simulation of the Performance of XDQRAP under a Range of Conditions

For a more complete description of the XDQRAP protocol see references [1] and [2]. We give here a brief description of a specific version of the protocol, the one that we feel is most appropriate for cable applications. This is the version that we simulated. Many variations are possible. A transmission of a cell proceeds in two steps, first reservation and then transmission. We will first describe the configuration at the physical level and then describe the reservation process and then the transmission process.
