Detailed Description

The packet header for the AM Radio Link Control (RLC) protocol packets.

This class has fields corresponding to those in an RLC header as well as methods for serialization to and deserialization from a byte buffer. It follows 3GPP TS 36.322 Radio Link Control (RLC) protocol specification.

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::LteRlcAmHeader::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.

Here is the caller graph for this function:

TypeId ns3::LteRlcAmHeader::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.

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

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.

void ns3::LteRlcAmHeader::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
