Traffic Pattern to Be Generated

To test AF_​XDP as in the example given in Example: Running DPDK-pktgen Traffic, a packet generator of choice can be used to generate test traffic to the ADQ server with the following characteristics:

• UDP protocol to connect to AF_​XDP sockets on the server.
• Destination port must match the $app_​port number used in the ADQ configuration on the AF_​XDP server (TC filter and ntuple configuration commands in AF_​XDP Server Configuration).
• To use all ADQ queues on the AF_​XDP server, the number of traffic streams (ports) should be equal to or a multiple of the number of ADQ queues configured on the AF_​XDP server ($num_​queues_​tc1 in AF_​XDP Server Configuration).
• Other variables, such as $packet_​size, can be configured to test the desired traffic pattern.
