Detailed Description

A Udp server. Receives UDP packets from a remote host. UDP packets carry a 32bits sequence number followed by a 64bits time stamp in their payloads. The application uses, the sequence number to determine if a packet is lost, and the time stamp to compute the delay.

Config Paths

ns3::UdpServer is accessible through the following paths with Config::Set and Config::Connect:

/NodeList/[i]/ApplicationList/[i]/$ns3::UdpServer

Attributes

Port: Port on which we listen for incoming packets.
- Set with class: ns3::UintegerValue
- Underlying type: uint16_t 0:65535
- Initial value: 100
- Flags: construct write read
PacketWindowSize: The size of the window used to compute the packet loss. This value should be a multiple of 8.
- Set with class: ns3::UintegerValue
- Underlying type: uint16_t 8:256
- Initial value: 32
- Flags: construct write read

Attributes defined in parent class ns3::Application

StartTime: Time at which the application will start
- Set with class: ns3::TimeValue
- Underlying type: Time -9223372036854775808.0ns:+9223372036854775807.0ns
- Initial value: +0.0ns
- Flags: construct write read
StopTime: Time at which the application will stop
- Set with class: ns3::TimeValue
- Underlying type: Time -9223372036854775808.0ns:+9223372036854775807.0ns
- Initial value: +0.0ns
- Flags: construct write read

No TraceSources are defined for this type.

Member Function Documentation

void ns3::UdpServer::DoDispose ( void )

protectedvirtual

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

Subclasses are expected to implement their real destruction code in an overriden 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::Application.
