Detailed Description

Send as much traffic as possible, trying to fill the bandwidth.

This traffic generator simply sends data as fast as possible up to MaxBytes or until the application is stopped (if MaxBytes is zero). Once the lower layer send buffer is filled, it waits until space is free to send more data, essentially keeping a constant flow of data. Only SOCK_STREAM and SOCK_SEQPACKET sockets are supported. For example, TCP sockets can be used, but UDP sockets can not be used.

void ns3::BulkSendApplication::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.

Here is the caller graph for this function:

void ns3::BulkSendApplication::SetMaxBytes ( uint32_t maxBytes )

Set the upper bound for the total number of bytes to send.

Once this bound is reached, no more application bytes are sent. If the application is stopped during the simulation and restarted, the total number of bytes sent is not reset; however, the maxBytes bound is still effective and the application will continue sending up to maxBytes. The value zero for maxBytes means that there is no upper bound; i.e. data is sent until the application or simulation is stopped.

Parameters

maxBytes the upper bound of bytes to send

void ns3::BulkSendApplication::StartApplication ( void )

Application specific startup code.

The StartApplication method is called at the start time specified by Start This method should be overridden by all or most application subclasses.
