Abstract: The decision within a packet processing device to transmit a newly arriving packet into a queue to await further processing or to discard the same packet is made by a flow control method and system. The flow control is updated with a constant period determined by storage and flow rate limits. The update includes comparing current queue occupancy to a threshold. The outcome of the update is adjustment up or down of the transmit probability value. The value is stored for the subsequent period of flow control and packets arriving during that period are subject to a transmit or discard decision that uses that value.

The flow control is updated with a constant period determined by storage and flow rate limits. The update includes comparing current queue occupancy to thresholds and also comparing present queue occupancy to previous queue occupancy. The outcome of the update is a new transmit probability value. The value is stored for the subsequent period of flow control and packets arriving during that period are subject to a transmit or discard decision that uses that value.

Abstract: A primary ARP server and a backup ARP server are connected to an ATM communications network. The primary and backup ARP servers each have associated ATM addresses. Also, a LIS is connected to the ATM communications network. Either the primary or backup ARP server is the active ARP server and resolves IP addresses to ATM addresses for the LIS. When the backup ARP server recognizes the removal of a redundancy virtual channel connection (VCC) between the backup ARP server and the primary ARP server, the backup ARP server registers using the ATM address associated with the primary ARP server. This allows the backup ARP server to take over for the primary ARP server to become the active ARP server.In addition, a primary default gateway and a backup default gateway are connected to the ATM communications network. These default gateways have associated ATM addresses. One of the primary and backup default gateways is active at a time.
