Detailed Description

Generate traffic to a single destination according to an OnOff pattern.

This traffic generator follows an On/Off pattern: after Application::StartApplication is called, "On" and "Off" states alternate. The duration of each of these states is determined with the onTime and the offTime random variables. During the "Off" state, no traffic is generated. During the "On" state, cbr traffic is generated. This cbr traffic is characterized by the specified "data rate" and "packet size".

Note: When an application is started, the first packet transmission occurs _after_ a delay equal to (packet size/bit rate). Note also, when an application transitions into an off state in between packet transmissions, the remaining time until when the next transmission would have occurred is cached and is used when the application starts up again. Example: packet size = 1000 bits, bit rate = 500 bits/sec. If the application is started at time 3 seconds, the first packet transmission will be scheduled for time 5 seconds (3 + 1000/500) and subsequent transmissions at 2 second intervals. If the above application were instead stopped at time 4 seconds, and restarted at time 5.5 seconds, then the first packet would be sent at time 6.5 seconds, because when it was stopped at 4 seconds, there was only 1 second remaining until the originally scheduled transmission, and this time remaining information is cached and used to schedule the next transmission upon restarting.

If the underlying socket type supports broadcast, this application will automatically enable the SetAllowBroadcast(true) socket option.

virtual void ns3::OnOffApplication::DoDispose ( void   )  [protected, virtual]

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.

static TypeId ns3::OnOffApplication::GetTypeId ( void   )  [static]
