Several hosts on an Ethernet hub
The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.
If a module type shows up more than once, that means it has been defined in more than one NED file.
EtherHost | Example host model with one Ethernet port and several traffic generators to create traffic in the test network. |
EtherHub | A generic wiring hub model. |
cable | (no description) |
If a module type shows up more than once, that means it has been defined in more than one NED file.
LargeNet | A large Ethernet LAN -- see model description here. |
Name | Type | Description |
---|---|---|
h | numeric const | number of hosts on the hub |
Name | Direction | Description |

in | input | |
out | output |
Name | Type | Description |
---|---|---|
hub.writeScalars | bool | enable/disable recording statistics in omnetpp.sca |
host[*].cli.destStation | string | module path name of destination station (must be blank if destAddress is given) |
host[*].cli.destAddress | string | destination MAC address (must be blank if destStation is given) |
host[*].cli.waitTime | numeric | interarrival time between sending requests; may be random value |
host[*].cli.reqLength | numeric | length of request packets (bytes); may be random value |
host[*].cli.respLength | numeric | length of response packets (bytes); may be random value |
host[*].cli.writeScalars | bool | enable/disable recording statistics in omnetpp.sca |
host[*].srv.writeScalars | bool | enable/disable recording statistics in omnetpp.sca |
host[*].llc.writeScalars | bool | enable/disable recording statistics in omnetpp.sca |
host[*].mac.promiscuous | bool | if true, all packets are received, otherwise only the ones with matching destination MAC address |
host[*].mac.address | string | MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0. |
host[*].mac.txrate | numeric | maximum data rate supported by this station (bit/s); actually chosen speed may be lower due to auto- configuration. 0 means fully auto-configured. |
host[*].mac.duplexEnabled | bool | whether duplex mode can be enabled or not; whether MAC will actually use duplex mode depends on the result of the auto-configuration process (duplex is only possible with DTE-to-DTE connection). |
host[*].mac.writeScalars | bool | enable/disable recording statistics in omnetpp.sca |
