Compound Module EthernetInterfaceNoQueue

File: NetworkInterfaces/Ethernet/EthernetInterfaceNoQueue.ned

Ethernet network interface. Assumes inifinite queue.

See also: EthernetInterface

mac: EtherMAC encap: EtherEncap

Usage diagram:

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.

Contains the following modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

EtherEncap

Performs Ethernet II encapsulation/decapsulation.

EtherMAC

Ethernet MAC layer. MAC performs transmission and reception of frames. Doesn't do encapsulation/decapsulation; see EtherLLC and EtherEncap for that. Also does not perform interface registration in RoutingTable -- that task is delegated to ARP, which makes it possible to use EtherMAC independent of the IP framework.

Gates:

Name Direction Description
physIn input
netwIn input
physOut output
netwOut output

Unassigned submodule parameters:

Name Type Description
mac.promiscuous bool

if true, all packets are received, otherwise only the ones with matching destination MAC address

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.

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.

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).

mac.writeScalars bool

enable/disable recording statistics in omnetpp.sca

encap.writeScalars bool

enable/disable recording statistics in omnetpp.sca
