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 152 bytes (on a 64-bit architecture).

Member Function Documentation

◆ Deserialize()

uint32_t ns3::CtrlBAckResponseHeader::Deserialize ( Buffer::Iterator start )

virtual

Parameters

start an 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.

◆ Print()

Parameters

os output 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
