Detailed Description

Class that monitors flows at the IPv6 layer of a Node.

For each node in the simulation, one instance of the class Ipv4FlowProbe is created to monitor that node. Ipv4FlowProbe accomplishes this by connecting callbacks to trace sources in the Ipv6L3Protocol interface of the node.

Definition at line 42 of file ipv6-flow-probe.h.

Member Enumeration Documentation

◆ DropReason

enumeration of possible reasons why a packet may be dropped

Enumerator
DROP_NO_ROUTE 

Packet dropped due to missing route to the destination.

DROP_TTL_EXPIRE 

Packet dropped due to TTL decremented to zero during IPv4 forwarding.

DROP_BAD_CHECKSUM 

Packet dropped due to invalid checksum in the IPv4 header.

DROP_QUEUE 

Packet dropped due to queue overflow.

Note: only works for NetDevices that provide a TxQueue attribute of type Queue with a Drop trace source. It currently works with Csma and PointToPoint devices, but not with WiFi or WiMax.

DROP_QUEUE_DISC 

Packet dropped by the queue disc.

DROP_INTERFACE_DOWN 

Interface is down so can not send packet.

DROP_ROUTE_ERROR 

Route error.

DROP_UNKNOWN_PROTOCOL 

Unknown L4 protocol.

DROP_UNKNOWN_OPTION 

Unknown option.

DROP_MALFORMED_HEADER 

Malformed header.

DROP_FRAGMENT_TIMEOUT 

Fragment timeout exceeded.

DROP_INVALID_REASON 

Fallback reason (no known reason)

Definition at line 58 of file ipv6-flow-probe.h.

Member Function Documentation

◆ DoDispose()

void ns3::Ipv6FlowProbe::DoDispose ( void  )
protectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::FlowProbe.
