A Fast Assignment Technique For Use In A Switching Arrangement The present invention relates to a fast packet assignment technique, and a TDMA or FDMA multi-port switching arrangement for implementing such technique. In the present technique, the total traffic in a twodimensional traffic matrix (T) from and to each of N remote service areas, regardless of destination or origination, is totaled to form separate input (R) and output (S) traffic vectors, respectively. Nonconflicting assignments are then made from these vectors for each packet or channel available during a predetermined time period while also providing the capability of substantially reducing multi-path or antenna sidelobe interference. An MxM switch (16) is designed to implement such technique which directs C input packets from M inputs (201-M) into separate memory locations (Zij). During the time period of the next C input packets, the MxM switch directs the presently stored packets to the proper ones of M outputs (271-M) at the appropriate time for transmission in the proper packet or channel to the destined remote service areas. In accordance with the present technique and switch, the M packets concurrently directed from memory to the M output ports can comprise more than one packet from a particular service area to other separate service areas. |
