In packet or block switching systems, it is sometimes desirable to minimize block transit time through the system. Many of these systems use store and forward techniques. One method of minimizing block transit time is to begin to forward the block before its end has been received. This is no problem if the effective data rate of the sending line is equal to or less than the receiving line. In cases where the sending line is faster, the sender may overrun the receiver and send erroneous data. Often a single storage module is divided into buffer areas, each capable of holding a data block. These buffers are shared between a multiplicity of receiving and sending lines.
