A simple traffic generator for the Ethernet model and the 802.11 model, and generally for any L2 model that accepts Ieee80211Ctrl control info on the packets. It should be connected directly to EtherEncap or an Ieee802NicXXX module.
The following diagram shows usage relationships between types. Unresolved types are missing from the diagram.

Name | Type | Description |
---|---|---|
EtherHost2 | compound module |
An example host with one Ethernet interface and an Ethernet traffic generator directly connected to it. This host model does not contain higher layer protocols (IP, TCP). By default is configured to use half-duplex MAC (CSMA/CD). |
Name | Type | Default value | Description |
---|---|---|---|
destAddress | string | "" |
destination MAC address, or module path name of destination station; empty means off |
etherType | int | 0 |
etherType to set on outgoing packets |
startTime | double | this.sendInterval |
time of sending the first packet |
stopTime | double | -1s |
time of finishing sending, negative values mean forever |
sendInterval | double |
interval between sending bursts |
|
numPacketsPerBurst | int | 1 |
number of packets to send per burst (packets within a burst are sent at the same simulation time) |
packetLength | int |
length of packets to send |
