Ipv4Address destinationAddress
Destination address.
Classifies packets by looking at their IP and TCP/UDP headers.
uint16_t destinationPort
Destination port.
std::map< FlowId, FlowPacketId > m_flowPktIdMap
Map to FlowIds to FlowPacketId.
def indent(source, debug, level)
Definition: check-style.py:286
Packet header for IPv4.
Definition: ipv4-header.h:33
virtual void SerializeToXmlStream(std::ostream &os, int indent) const
Serializes the results to an std::ostream in XML format.
FiveTuple FindFlow(FlowId flowId) const
Searches for the FiveTuple corresponding to the given flowId.
bool operator<(const int64x64_t &lhs, const int64x64_t &rhs)
Less than operator.
Definition: int64x64-128.h:356
Every class exported by the ns3 library is enclosed in the ns3 namespace.
Structure to classify a packet.
Ipv4 addresses are stored in host order in this class.
Definition: ipv4-address.h:40

Definition: event-id.cc:95
bool Classify(const Ipv4Header &ipHeader, Ptr< const Packet > ipPayload, uint32_t *out_flowId, uint32_t *out_packetId)
try to classify the packet into flow-id and packet-id
std::map< FiveTuple, FlowId > m_flowMap
Map to Flows Identifiers to FlowIds.
Ipv4Address sourceAddress
Source address.
uint32_t FlowId
Abstract identifier of a packet flow.
Provides a method to translate raw packet data into abstract flow identifier and packet identifier pa...
