module interface

Interface for Ethernet network interfaces.

Inheritance diagram

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

Implemented by

Name	Type	Description
EthernetCutthroughInterface	compound module	Represents an Ethernet network interface with Ethernet cut-through switching support. In contrast with store-and-forward switching, Ethernet cut-through switching can begin the transmission of the outgoing packet before the reception of the corresponding incoming packet ends. Ethernet cut-through switching can significantly reduce end-to-end delay in the network.
EthernetInterface	compound module	Represents an Ethernet network interface.
EthernetPlcaInterface	compound module	Implements a network interface that is suitable for use in Ethernet 10BASE-T1S multidrop links. Such a multidrop link uses the Ethernet Phyisical Layer Collision Avoidance (PLCA) protocol. The protocol is defined in the IEEE 802.3cg-2019 standard. This network interface can be used in any network node module (e.g. ~StandardHost) that allows replacing its network interfaces. All network interfaces on the same multidrop link must use this module.
ExtLowerEthernetInterface	compound module	Provides an Ethernet network interface suitable for emulation. The lower part of the network interface is realized in the real world using a real Ethernet socket of the host computer which is running the simulation.
ExtUpperEthernetInterface	compound module	Provides an Ethernet network interface suitable for emulation. The upper part of the network interface is realized in the real world using a real TAP device of the host computer which is running the simulation.
LayeredEthernetInterface	compound module	Implements an Ethernet network interface.

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.
