Detailed Description

The Extended Supported Rates Information Element

This class knows how to serialise and deserialise the Extended Supported Rates Element that holds (non-HT) rates beyond the 8 that the original Supported Rates element can carry.

The SupportedRates class still records all the rates, and an instance of ExtendedSupportedRatesIE lies within SupportedRates.

ns3::ExtendedSupportedRatesIE::ExtendedSupportedRatesIE ( SupportedRates rates)

Create an extended supported rates information element from the given rates.

Parameters
rates

References m_supportedRates.

Member Function Documentation

uint8_t ns3::ExtendedSupportedRatesIE::DeserializeInformationField ( Buffer::Iterator  start,
uint8_t  length 
)
virtual

Deserialize information (i.e., the body of the IE, not including the Element ID and length octets)

Parameters
startan iterator which points to where the information should be written.
length
Returns
the number of bytes read

Implements ns3::WifiInformationElement.

Definition at line 210 of file supported-rates.cc.

References ns3::SupportedRates::m_nRates, ns3::SupportedRates::m_rates, m_supportedRates, MAX_SUPPORTED_RATES, NS_ASSERT, and ns3::Buffer::Iterator::Read().

+ Here is the call graph for this function:

WifiInformationElementId ns3::ExtendedSupportedRatesIE::ElementId ( ) const
virtual

Own unique Element ID.

Implements ns3::WifiInformationElement.

Definition at line 146 of file supported-rates.cc.

References IE_EXTENDED_SUPPORTED_RATES.

uint8_t ns3::ExtendedSupportedRatesIE::GetInformationFieldSize ( ) const
virtual

Length of serialized information (i.e., the length of the body of the IE, not including the Element ID and length octets.

This is the value that will appear in the second octet of the entire IE - the length field)

Returns
the length of serialized information

Implements ns3::WifiInformationElement.

Definition at line 152 of file supported-rates.cc.

References ns3::SupportedRates::m_nRates, m_supportedRates, and NS_ASSERT.

uint16_t ns3::ExtendedSupportedRatesIE::GetSerializedSize ( void  ) const

Return the serialized size of this supported rates information element.

Returns
the serialized size of this supported rates information element

Buffer::Iterator ns3::ExtendedSupportedRatesIE::Serialize ( Buffer::Iterator  start) const

This information element is a bit special in that it is only included if there are more than 8 rates.

To support this we override the Serialize and GetSerializedSize methods of WifiInformationElement.

Parameters
start
Returns
an iterator
