摘要： Packet flow control techniques are disclosed. In one example case, a flow control method is provided that includes transmitting a plurality of packets with an inter-packet gap disposed between neighboring packets, and increasing the length of the inter-packet gap to decrease packet rate, wherein the increased length is selected based on severity of a congestion condition. In another example case, a flow control system is provided that includes circuitry for transmitting and/or receiving a plurality of packets with an inter-packet gap disposed between neighboring packets, and circuitry for increasing the length of the inter-packet gap to decrease packet rate, wherein the increased length is selected based on severity of a congestion condition. The techniques can be carried out at one node of a communication system (such as in a backplane switch) or multiple nodes (such as between a backplane switch and a circuit board operatively coupled to the backplane).

摘要： The present disclosure relates generally to an integrated circuit configured to route multicast data packets using device vectors. A method according to one embodiment may include communicating with an external device using port. The method may also include storing a multicast data packet and a master device vector in memory. The method may also include de-queueing the master device vector from memory, generating an additional device vector based on the master device vector, and transmitting the multicast data packet and an additional device vector to an external device via a port. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

摘要： A method and system is provided for a multi-level memory. The system includes an internal memory and an external memory. Data packets are received through one or more input ports and initially stored in the internal memory. A control unit determines whether there is congestion of resources within the system and transfers data packets to external memory to ease the congestion. Data packets are eventually transferred from the internal or external memory to one or more output ports.
