pure virtual |
| packet | the packet we want to insert into aggregatedPacket. |
| last | true if it is the last packet. |
| isSingleMpdu | true if it is a single MPDU |
Adds A-MPDU subframe header and padding to each MPDU that is part of an A-MPDU before it is sent.
Implemented in ns3::MpduStandardAggregator.
|
pure virtual |
| packet | Packet we have to insert into aggregatedPacket. |
| aggregatedPacket | Packet that will contain packet, if aggregation is possible. |
Adds packet to aggregatedPacket. In concrete aggregator's implementation is specified how and if packet can be added to aggregatedPacket.
Implemented in ns3::MpduStandardAggregator.
|
pure virtual |
| packet | the packet we want to insert into aggregatedPacket. |
| aggregatedPacket | packet that will contain the packet of size packetSize, if aggregation is possible. |
This method performs a VHT/HE single MPDU aggregation.
Implemented in ns3::MpduStandardAggregator.
|
pure virtual |
| packet | the Packet |
Calculates how much padding must be added to the end of an aggregated packet, after that a new packet is added. Each A-MPDU subframe is padded so that its length is multiple of 4 octets.
Implemented in ns3::MpduStandardAggregator.
|
pure virtual |
| packetSize | size of the packet we want to insert into aggregatedPacket. |
| aggregatedPacket | packet that will contain the packet of size packetSize, if aggregation is possible. |
| blockAckSize | size of the piggybacked block ack request |
This method is used to determine if a packet could be aggregated to an A-MPDU without exceeding the maximum packet size.
Implemented in ns3::MpduStandardAggregator.

static |
Deaggregates an A-MPDU by removing the A-MPDU subframe header and padding.
