2. Quick Start

This section describes how to get started quickly.

First, install nettimer as described in Section 3.

This example only covers the common case of actively measuring the bottleneck link:
	nettimer ––active_probing_addresses remote_host 
      
where remote_host is the name or address of the remote host that you want to measure to.

The output looks something like:
BW: 7995536.719157 Error: 0.554183 Samples: 12
Active probing statistics:
  packets sent: 16 
  packets received: 16
  timeouts: 0
KLException caught in program: "nettimer"

  Passed at file: "packet_capture.c" function: "packet_capture_event_handler" line: XXX
    meaning: "Client exception."

  Thrown at file: "active_probing.c" function: "active_probing_packet_new" line: XXX
    meaning: "Exceeded active probing sent packets maximum."

The first line of the output gives the bandwidth estimate, error estimate, and the number of samples used to generate the estimate.
