IEthernetLayer

module interface

Module interface for Ethernet protocol layer implementations. Implementations typically handle the encapsulation of higher layer packets into Ethernet frames for transmission and the decapsulation of received Ethernet frames for delivery to higher layers.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
EthernetEncapsulation	simple module	Performs Ethernet II or Ethernet with LLC/SNAP encapsulation/decapsulation.
EthernetLayer	compound module	(no description)
OmittedEthernetEncapsulation	compound module	Implements the given module interface and can be used as an optional module that removes itself from the module hierarchy during initialization.

Used in compound modules

Name	Type	Description
AccessPoint	compound module	A wireless access point device that connects wireless stations (like WirelessHost) to a wired network. Supports multiple wireless radios and multiple Ethernet ports.
BGPRouterEx	compound module	Example IP router with BGPv4 and OSPFv4 support.
EthernetHost	compound module	A simplified network device that communicates directly over Ethernet without higher layer protocols like IP or TCP. It provides a basic host model for Ethernet-only simulations.
EthernetHost2	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).
EthernetSwitch	compound module	EthernetSwitch models a Layer 2 Ethernet switch with support for various IEEE 802.1 protocols and features. It provides frame forwarding based on MAC addresses and implements multiple switching technologies.
LinkLayerNodeBase	compound module	An extension of the basic node infrastructure with link layer functionality. Provides support for various network interfaces and link layer protocols, forming the foundation for network connectivity.
