Detailed Description

Headers for BlockAck response.


Introspection did not find any typical Config paths.

802.11n standard includes three types of BlockAck:

  • Basic BlockAck (unique type in 802.11e)
  • Compressed BlockAck
  • Multi-TID BlockAck For now only basic BlockAck and compressed BlockAck are supported. Basic BlockAck is also default variant.


No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 80 bytes (on a 64-bit architecture).

Member Function Documentation

◆ Deserialize()

uint32_t ns3::CtrlBAckResponseHeader::Deserialize ( Buffer::Iterator  start)
virtual
Parameters
startan iterator which points to where the header should read from.
Returns
the number of bytes read.

This method is used by Packet::RemoveHeader to re-create a header from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this header in real networks.

Note that data is not actually removed from the buffer to which the iterator points. Both Packet::RemoveHeader() and Packet::PeekHeader() call Deserialize(), but only the RemoveHeader() has additional statements to remove the header bytes from the underlying buffer and associated metadata.

Implements ns3::Header.

Parameters
seqthe sequence number
Returns
If we are using basic block ack, return value represents index of block of 16 bits for packet having sequence number equals to seq. If we are using compressed block ack, return value represents bit to set to 1 in the compressed bitmap to indicate that packet having sequence number equals to seq was correctly received.

Parameters
osoutput stream This method is used by Packet::Print to print the content of a header as ascii data to a c++ output stream. Although the header is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace. i.e.: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5
