Detailed Description

Headers for Block ack request.

802.11n standard includes three types of block ack:

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

Doxygen introspection did not find any typical Config paths.
No Attributes are defined for this type.
No TraceSources are defined for this type.

Member Function Documentation

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

virtual

Parameters

start

an iterator which points to where the header should written.

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.

Implements ns3::Header.

Definition at line 121 of file ctrl-headers.cc.

References ns3::Buffer::Iterator::GetDistanceFrom(), NS_FATAL_ERROR, NS_LOG_FUNCTION, and ns3::Buffer::Iterator::ReadLsbtohU16().

TypeId ns3::CtrlBAckRequestHeader::GetInstanceTypeId ( void  ) const

virtual

Returns

the TypeId associated to the most-derived type of this instance.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Implements ns3::ObjectBase.

Definition at line 60 of file ctrl-headers.cc.

References NS_LOG_FUNCTION.

uint32_t ns3::CtrlBAckRequestHeader::GetSerializedSize ( void  ) const

virtual

Returns

the expected size of the header.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. This method should return the number of bytes which are needed to store the full header data by Serialize.

Implements ns3::Header.

Definition at line 74 of file ctrl-headers.cc.

References NS_FATAL_ERROR, and NS_LOG_FUNCTION.

void ns3::CtrlBAckRequestHeader::Print ( std::ostream &  os ) const

virtual

Parameters

os

output stream This method is used by Packet::Print to print the content of a trailer as ascii data to a c++ output stream. Although the trailer 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

Implements ns3::Header.

Definition at line 67 of file ctrl-headers.cc.

References NS_LOG_FUNCTION.

void ns3::CtrlBAckRequestHeader::Serialize ( Buffer::Iterator  start ) const

virtual

Parameters

start

an iterator which points to where the header should be written.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. The data written is expected to match bit-for-bit the representation of this header in a real network.

Implements ns3::Header.

Member Data Documentation

bool ns3::CtrlBAckRequestHeader::m_barAckPolicy

private

The lsb bit of the BAR control field is used only for the HT (High Throughput) delayed block ack configuration. For now only non HT immediate block ack is implemented so this field is here only for a future implementation of HT delayed variant.
