Constructor Detail

AvnmpBW

public AvnmpBW()

Method Detail

queueSize

protected long queueSize(int port)

Incoming Active Node Queue size. This is an accumulator of all packets received since startup.

Parameters:

port - The receive port number.

Returns:

The current incoming queue size.

xmitRate

protected double xmitRate()

This method returns the total number of bytes transmitted by this node divided by the total amount of time this node has been running.

Returns:

The transmit bandwidth used.

recvRate

protected double recvRate()

This method returns the total number of bytes received by this node divided by the total amount of time this node has been running.

Returns:

The receive bandwidth used.

exec

public void exec()

This is the main processing for this active packet. The primary task is to add itself to the receiving node's input queue.

Overrides:
