Abstract
A method including providing a network switch, including switching circuitry, packet drop decision circuitry, packet duplication circuitry, and packet exporting circuitry, and performing the following in the network switch: switching packets in the switching circuitry, identifying a packet that is to be dropped in the packet drop decision circuitry, duplicating the packet that is to be dropped in the packet duplication circuitry, producing a first packet and a second packet, exporting the first packet to a tail-drop packet buffer in the packet exporting circuitry, and exporting the second packet to a cyclic packet buffer in the packet exporting circuitry. Related apparatus and methods are also provided. The abstract is not intended to be limiting.
Claims20
A method comprising:
- providing a network switch, comprising switching circuitry, packet drop decision circuitry, packet duplication circuitry, and packet exporting circuitry;
- and
- performing the following in the network switch:
- switching packets in the switching circuitry;
- identifying a packet that is to be dropped in the packet drop decision circuitry;
- duplicating the packet that is to be dropped in the packet duplication circuitry, producing a first packet and a second packet;
- exporting the first packet to a tail-drop packet buffer in the packet exporting circuitry;
- and
- exporting the second packet to a cyclic packet buffer in the packet exporting circuitry.
Apparatus comprising:
- a network switch comprising:
- switching circuitry configured for switching packets;
- packet drop decision circuitry configured for identifying a packet that is to be dropped;
- packet duplication circuitry configured for duplicating the packet that is to be dropped, producing a first packet and a second packet;
- and
- packet exporting circuitry configured for exporting the first packet to a tail-drop packet buffer and for exporting the second packet to a cyclic packet buffer.
