IP Traffic Test & Measure Features


IP Generator Overview

Generates up to 16 simultaneous UDP (Unicast, Multicast or Broadcast) and/or TCP connections and/or ICMP connections. The connections may be established following three different testing modes:

Unitary Testing Mode: You may select from two different types of data generator:
Internal data generator: you may select the traffic generator data source and configure packet size and inter packet delay for each connection. Using the ICMP protocol you may set:
Request packet number and content: packet generator (fixed, random, alternate and increasing/decreasing).
Request data size: fixed, random, alternate and increasing/decreasing.
Reply Receiving timeout: fixed, random, alternate and increasing/decreasing or use of a mathematical law.
'IP Traffic Test & Measure' offers three different data sources:
Automatic data generator: using mathematical laws (2).
Packet generator: many parameters may be defined (number of packets to send, inter packet delay, packet contents,...).
File: selection of a file to send (2).
Automatic Testing Mode (2): The user selects one mathematical law for connection generation starting time and another mathematical law for data volume to send, in order to generate up to 16 outgoing IP connections.This mode can not be used with ICMP connections.
Replay Sniffed Traffic(2): The user selects a traffic file previously captured in sniffer mode by 'IP Traffic' and the IP generator replays this IP traffic file with timing according to time capture (IP resolution addressing is made by the user before replay).

(2) Not available with ICMP.

IP Generator Statistics:

Different statistics parameters are displayed by the 'IP Generator' module for each connection.
Sent throughput(1), Received throughput(1), Sent packet throughput(1), Received packet throughput(1), Sent data volume(1), Received data volume (volume of data sent by the remote)(1), Sent packets, Received packets (packets sent by the remote), Data volume to send(1), Remaining volume (of data to send)(1), Seq. numb errors (sequence numbering errors),Mean RTT (Round Trip Time),
Min RTT, Max RTT, Jitter (1).

(1) These statistics are not available with ICMP protocol.


IP Answering Overview

Receives traffic (up to 16 simultaneous connections), and each connection may follow a different working mode: Absorber, Absorber file, Echoer, Echoer file, Generator or Disable.

The IP answering feature enables configuration of:

Remote IP connection: Source IP address, port number and protocol from which the connection is received.

Receiving working mode from the following 4 options:

Echoer Mode: When a receiving connection is operating in echoer mode, the received data is sent back to the IP generator.
Echoer File Mode: When a receiving connection is operating in this mode, the received data is sent back to the IP generator and is also saved in a file.
Absorber Mode: With this working mode, once the connection is received, 'IP Traffic' absorbs data on that connection.
Absorber File Mode: When a receiving connection is operating in Absorber File mode, IP answering will save received data in a file.
Receiving Statistics for each Connection: Different statistics parameters are displayed by the IP answering module for each connection:
Sent throughput, Received throughput, Sent packet throughput, Received packet throughput, Sent data volume,Received data volume (volume of data sent by the remote),Sent packets,Received packets (packets sent by the remote),Data volume to send,Remaining volume (of data to send), Seq. numb errors (sequence numbering errors), Data not echoed,Jitter,These statistics may be saved in a CSV file defined by the user.


Traffic Sniffer Overview

Traffic sniffer enables traffic to be captured in a file. This is used for 2 purposes:

  • Off line statistics.
  • In order to replay traffic via the IP generator.
Capture Parameters: IP traffic can be captured with 2 options: All IP traffic or IP traffic on connections specified by the user.
Capture Sniffed Traffic in a File: Once capture parameters have been defined, captured traffic may be saved in a file.
Run Analysis Algorithm on Sniffed Traffic file to Generate Data Traffic Files: From an IP capture file, IP Traffic uses an internal algorithm to produce two traffic files. The goal is to find in the input traffic file the communication entities (sender and receiver) and then produce two traffic files to replay.

 

Traffic Observer Overview

Visualize statistics and graphics for different parameters and for each connection of the IP generator
or the IP answering module:
IP throughput, Inter packet delay, Packet Erasure Rate quality (PER quality) and Packet transit delay.
Two Operating Modes to Display Statistics (online and offline): On-line (real time) and off-line (analysis of traffic files captured by the traffic sniffer). With the off-line mode, user can replay traffic files by using a ‘video recorder’ mode (play, pause, stop) with index management.
Graphical Analyser: Many functions (statistical laws, user defined trigger, …) to analyse the following parameters over the IP network used: IP throughput, inter packet delay, PER quality and packet transit delay. This analyser allows graphical correlation of several parameters and is very useful for precise analysis of characteristics and IP network problems.
Statistics: Export statistics in a file.
