Abstract
A device, communication system, and method are provided. In one example, a system for switch generated explicit packet discard notifications is described that includes circuits to detect a packet is to be dropped; extract information from the packet to be dropped; and generate a notification using the extracted information from the packet to be dropped. The system also includes an interface to send the generated notification to a source associated with the packet to be dropped, wherein the notification is generated and sent from a switch.
Claims18
A system, comprising:
- a switch to route a plurality of packets over a communication network, the switch comprising processing circuitry to:
- detect that a packet of the plurality of packets will arrive out of sequence at a destination;
- extract information from the detected packet;
- and
- generate a notification using the extracted information;
- and
- an interface to send the notification to a source associated with the plurality of packets wherein the notification comprises an Out of Sequence (OOS) Negative Acknowledgement (NACK) message which informs the source that the detected packet will arrive out of sequence at the destination.
A switch, comprising:
- processing circuitry to:
- detect that a packet of a plurality of packets will arrive out of sequence at a destination;
- extract information from the detected packet;
- generate a notification using the extracted information;
- and
- send the notification to a source associated with the plurality of packets, wherein the notification comprises an Out of Sequence (OOS) Negative Acknowledgement (NACK) message which informs the source that the detected packet will arrive out of sequence at the destination.
A method, comprising:
- detecting, at a switch, that a packet of a plurality of packets will arrive out of sequence at a destination;
- extracting, at the switch, information from the detected packet;
- generating, at the switch, a notification using the extracted information;
- and
- sending, at the switch, the notification to a source associated with the plurality of packets, and wherein the notification comprises an Out of Sequence (OOS) Negative Acknowledgement (NACK) message which informs the source that the detected packet will arrive out of sequence at the destination.
