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.

If the attribute "EnableSeqTsSizeHeader" is enabled, the application will use some bytes of the payload to store an header with a sequence number, a timestamp, and the size of the packet sent. Support for extracting statistics from this header have been added to ns3::PacketSink (enable its "EnableSeqTsSizeHeader" attribute), or users may extract the header via trace sources.

◆ SetMaxBytes()

void ns3::BulkSendApplication::SetMaxBytes ( uint64_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
maxBytesthe upper bound of bytes to send
