Detailed Description

Introspection did not find any typical Config paths.

QKDCommandTag is used to describe the content of the packet payload.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 16 bytes (on a 64-bit architecture).

QKDCommandTag is used in routing protocols to mark the packet that needs to be analyzed further from L4 layer. For example, we mark DSDV packet using this Tag, by using "SetCommand('R')" and "SetRoutingProtocolNumber(DSDV_PACKET_HEADER_PROTOCOL_NUMBER)" Later, in QCrypto by analyzing the tag we know that the packet contains DSDV headers that needs to be encrypted. Without the tag, there is no way to know what is inside TCP/UDP payload. Tag is removed after encryption. If the tag has some other value, such as "SetCommand('A')" it is not a routing packet, and the payload of the TCP/UDP header is encrypted as it is.

Note: This mechanism is mandatory since in the NS-3 simulator, we cannot provide the packet with all its headers and payload in a simple array of bytes or simmilar (version 3.29).

Member Function Documentation

void ns3::QKDCommandTag::Deserialize ( TagBuffer i )

virtual

Parameters

i	the buffer to read data from.

Read the content of the tag from the provided tag buffer. DO NOT attempt to read more bytes than you wrote with Tag::Serialize.

Implements ns3::Tag.

Here is the caller graph for this function:

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

virtual

Get the most derived TypeId for this Object.

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