Detailed Description

Test data transmission between two MLDs.

This test sets up an AP MLD and two non-AP MLDs having a variable number of links. The RF channels to set each link to are provided as input parameters through the test case constructor, along with the identifiers (starting at 0) of the links that cannot switch PHY band (if any). This test aims at veryfing the successful transmission of both unicast QoS data frames (from one station to another, from one station to the AP, from the AP to the station) and broadcast QoS data frames (from the AP or from one station). In the scenarios in which the AP forwards frames (i.e., from one station to another and from one station to broadcast) the client application generates only 4 packets, in order to limit the probability of collisions. In the other scenarios, 8 packets are generated. When BlockAck agreements are enabled, the maximum A-MSDU size is set such that two packets can be aggregated in an A-MSDU. The MPDU with sequence number equal to 1 is corrupted (once, by using a post reception error model) to test its successful re-transmission, unless the traffic scenario is from the AP to broadcast (broadcast frames are not retransmitted) or is a scenario where the AP forwards frame (to limit the probability of collisions).

When BlockAck agreements are enabled, we also corrupt a BlockAck frame, so as to simulate the case of BlockAck timeout. Both the case where a BlockAckReq is sent and the case where data frame are retransmitted are tested. Finally, when BlockAck agreements are enabled, we also enable the concurrent transmission of data frames over two links and check that at least one MPDU is concurrently transmitted over two links.
