LanTraffic
|
|
.
The main functions offered by LanTraffic V2
menus are:
| |
-
the management of user contexts: 'new', 'open', 'save', and 'save
as'
(1 context is defined as the whole set of parameters
for all connections) |
| |
- TCP parameter configuration: 'TCP buffer size' and 'TCP Window size'
for the Microsoft TCP/IP stack.
|
| |
- statistics display and management of throughput sampling parameters.
|
| |
- File downloading between two LanTraffic
V2: so one can recover the absorbed data from a remote
LanTraffic V2.
|
. Global IP traffic statistics
are continuously displayed for the Sender and the Receiver:
| |
-
the number of active connections, |
| |
-
the number of failed connections, |
| |
-
total sent throughput, |
| |
-
total received throughput. |
|
|
|
|
. Main functions for the IP traffic generator (Sender)
The Sender portion generates up to 16 simultaneous IP connections (TCP
or UDP). Connections can be generated in two different working modes:
| |
- the unitary testing mode: each connection may be run independently
(start/stop), |
| |
-
the automatic testing mode: the user predefined connections are
automatically run with a user programmed definition of parameters.
|
IP connection parameters:
| |
-
IP address
- port number
- protocol (TCP or UDP)
- (optional) file name to save received data for the connection
- for the unitary testing mode:
| |
*
data traffic generation (3 possible choices)
| |
.
mathematical law: uniform, exponential or pareto,
. packet generator contents: fixed, random, alternate
or increasing / decreasing,
. name of file to be sent.
|
* packet size: fixed, random, alternate or increasing /
decreasing,
* inter packet delay: fixed, random, alternate or increasing
/ decreasing,
* RTT option (Round Trip Time).
|
|
Parameters for the automatic test mode:
The automatic testing mode is a mode in which all enabled connections
are generated together following a “Starting time connections generation”
law and a “Data volume to send” law.
| |
- selection of IP connections (from 1 to 16) |
| |
- starting time connections generation law: uniform or exponential,
|
| |
- data volume to send law: uniform, exponential or pareto. |
LanTraffic V2 enables to save all
the RTT informations in a file for all connection with the RTT option
on.
Traffic statistics for IP connections (Sender)
| |
-
instant throughput, |
| |
-
data sent (UDP packets or TCP bytes), |
| |
-
data received (UDP packets or TCP bytes) |
| |
- meaningful only if receiver in echo mode |
|
| |
|
.
Main functions for the IP Receiver (up to 16 simultaneous
connections)
Parameters for each IP connection
| |
-
IP address |
| |
- IP address |
| |
-
protocol (TCP or UDP) |
| |
- receiving mode selected: echoer, absorber, file absorber
or disable.
|
Traffic statistics for each IP connection
| |
- instant throughput, |
| |
- received data (UDP packets or TCP bytes), |
| |
-
echoed data (UDP packets or TCP bytes) |
| |
-
meaningful if in the echoer working mode, |
| |
-
sequence numbering errors. |
.
On
the whole, the LanTraffic V2 manages
32 IP connections simultaneously, and a general graphics display visualizes
Sender and Receiver throughputs.
.
System requirements:
LanTraffic V2 is operating under
the following Windows operating systems:
98, NT4, 2000, XP and Windows Server 2003 with a 1024 x 768 minimum screen resolution.
