IP Traffic - Test & Measure Traffic Generator & QoS Measurement Tool for IP Networks (IPv4 & IPv6) |
 |
Overview & Applications
|
|
IP Traffic -
Test & Measure
is a traffic generator for IP networks using different protocols: |
IP Traffic - Test & Measure uses the Microsoft Windows TCP/IP stack (Winsock2 interface), and is independent of any transmission or telecom line. Any transmission link managed by the Windows operating system can be used: LAN (Ethernet, Token-ring, hyperlan...), WLAN (Wi-Fi, WiMax...), WAN (modem, ISDN, ATM, ADSL, FTTx, satellite...), remote access, PLC, mobile or cellular networks.
IP Traffic - Test & Measure can be used to get high accuracy measurements by using optional hardware providing a very precise time reference thanks to both the Time Devices (z100, z200 or z300 device) synchronized by GPS and our very precise clock (zClock).

Please refer to the PDF document for a general overview of IP Traffic - Test & Measure software |
 |
IP Traffic - Test & Measure is composed of four modules:
- IP Answering to receive IP traffic on 16 simultaneous connections with different working modes: absorber, echoer and generator
- Traffic Sniffer to capture traffic files at the driver level (under the TCP/IP stack) in order to calculate traffic statistics and timestamp IP packets (sent and received).
The IP Generator module can replay the captured traffic files.
- Traffic Observer is a powerful graphic tool to display and visualize traffic statistics of IP connections. Statistics are displayed in real time [on-line mode] or by using an off-line mode.
IP Generator features
* 3 working modes: Unitary mode (each connection can be parameterized independently by using the internal or external data generator), Automatic mode (parameters: starting time connections generation and data volume to send on connections), and Replay mode (parameter: data traffic file to replay).
* Internal data generator characteristics
- Traffic generator type: packets generator (packets number or infinite, packet contents: fix, random, alternate, increasing/decreasing) or Mathematical law or file to send.
- data size (fix, random, alternate, increasing/decreasing)
- inter packet delay (fix, random, alternate, increasing/decreasing)
- optional: throughput limit (Mean Throughput or Mean Packet Throughput)
* External data generator characteristics
- User File or User DLL
- Loop counter with delay between each loop
* Optional parameters
- Time code (RTT: Round Trip Time)
- DSCP (Differentiated Services Code Point)
- TTL (Time to Live)
* Statistics: Sent & Received throughput, Sent & Received packet throughput, Sent & Received packets,
Sequence numbering errors, RTT (Min, Max, Mean), Jitter and more...
IP Answering features
* 5 working modes: Echoer, Echoer file, Absorber, Absorber file and Generator
* Statistics: Sent & Received throughput, Sent & Received packet throughput, Sent & Received packets,
Sequence numbering errors, Jitter and more...
Traffic Sniffer features
Sent and received packets are time-stamped by the Traffic Sniffer (under the TCP/IP stack) to calculate statistics and can be saved into a file to generate captured traffic files. IP filters can be defined to capture more precisely the traffic and reduce the amount of data to save into the file.
From one traffic file captured by the Traffic Sniffer, an analysis algorithm produces two data files (IP packets sent and received) that can be replayed by the IP Generator module.
Traffic Observer features
This module displays and graphs statistical values provided by the IP Traffic - Test & Measure driver (under the TCP/IP stack).
- Numerical values for each IP connection: IP Throughput Snapshot (Tx & Rx), IP Throughput Average (Tx & Rx), UDP or TCP Throughput (Tx & Rx), Inter Packet Delay (Tx & Rx), Packet Transit Delay (Tx & Rx), Packet Erasure Rate (Tx & Rx)
- Graphics for each IP connection with average, standard deviation and confidence distance: IP Throughput (Tx & Rx), Inter Packet Delay (Tx & Rx), Packet Transit Delay (Tx & Rx), Packet Erasure Rate (Tx & Rx)
- Packet statistics display for each packet: status (lost or sent, transit delay, IP size, IP identification
- Packet statistics display for each IP connection: number of sent packets, mean transit delay, mean jitter, number and percentage of lost packets, number of retransmitted TCP packets.
Hardware options
Three Time Receivers models (z100, z200 and z300) synchronized by GPS are available according to the conditions of use and the needed accuracy. A high precision clock (zClock) can be added with the z100 and z200 models to improve the measure accuracy. A parallel port (EPP mode) is needed to connect the zClock product to the PC.
| z100 |
GPS Time Equipement Timing & Navigation |
|
Based on the Trimble Copernicus technology (Trimble OEM), this sensitive GPS receiver acquires autonomously GPS satellite signals and quickly generates reliable position in extremely challenging environments and even under poor signal conditions. It is recommended to use an outdoor antenna for best results. |
| z200 |
GPS Time Equipment High Precision Timing |
|
Designed to provide an accurate PPS (pulse per second) signal to use in measurement and industrial applications, this GPS timing module is designed to be used in indoor or outdoor static applications, requiring accurate time stamp reference information. It delivers accurate pps signal, even in very poor signal level environments (indoor, urban canyons and obscured environments) or when only 1 satellite is visible and being tracked. If the satellites signals are completely lost, the hold-over mode enables the module to keep sending the pps signal, with low drift over time. |
|
GPS Time Equipment High Precision NTP Time Server |
z300-C
z300-R |
This high precision NTP time server with PoE (Power over Ethernet) is designed for indoor or outdoor use and is synchronized by GPS, in order to provide accurate timing information for network synchronization and measurement applications. It delivers accurate timing information, even in poor signal level conditions. Thanks to its self-survey mode, the accuracy of the timestamp (compliant with SNTP protocol) is less than 1, 10 or 100μs (depending upon the version), and is achievable even with only 1 satellite being tracked. z300 is available in different metal housings, either compact (z300-C) or 19" rack mounted form factor (z300-R). The z300 product is well-suited for static applications (for mobile applications, we recommend the use of z400 or z500 product). |
|
High Precision Clock |
|
The Real Time Clock (RTC) built into most common machines is far from being reliable and most RTCs drift considerably over time. Based on a high stability OCXO (Oven-Controlled Crystal Oscillator) with a fast warm up, the zClock product offers a very precise clock (0,27 ppm) to any PC applications all that in a small and compact device. By using zClock, the application can rely on a precise clock with a drift lower than 1 millisecond for 1 hour on 1 year. |

Automation Tool for IP Traffic - Test & Measure
The add-on software Automation Tool for IP Traffic allows you to edit scenarios, carry out scenarios, set the parameters and pilot IP Traffic - Test & Measure automatically on the same PC.
A scenario is a succession of commands and instructions.
A command is used to set parameters and/or activate a function of IP Traffic - Test & Measure.
For example the Set and Start connection(s) command helps to set parameters for IP connections and to start the traffic on these connections. With such command you specify the IP address, port number, protocol, packet size, inter packet delay, duration, etc. and you start the traffic generation for these connections.
An instruction is used by the Automation Tool to create an internal process. For example, the Wait Date/Time instruction suspends the scenario execution up to the specified date and time before to continue.
By using the Automation Tool for IP Traffic you can:
- Set automatically the parameters of IP Traffic - Test & Measure,
- Start and stop IP connections based on timers,
- Execute the scheduled operations in accordance with your own timing,
- Make repetitive tests operations automatically,
- Simplify the tests reproduction,
- And more…
