ABSTRACT:
A Buffer Management System for a general multipoint packet switching network where the network has terminals transmitting data in the form of packets belonging to multiple channels over communication links through a packet switch array, the packet switches of the array receiving incoming packets from input data links and having memory arrays for temporarily storing the incoming packets for retransmitting the stored packets over output links. The Buffer Management System determines whether a packet should be stored, retransmitted, or discarded during an overload condition by identifying each incoming packet as either an excess packet or a nonexcess packet based on the number of packets stored in the memory array of the same channel as the incoming packet, and writing an incoming nonexcess packet into the memory array when the memory array is full and at least one excess packet is in the memory array and for discarding the excess packet from the memory array.
