IIeee80211Llc

module interface

Module interface for IEEE 802.11 Logical Link Control (LLC) implementations. LLC defines the interface between the MAC layer and network layer in IEEE 802.11 networks. Implementations handle encapsulation and decapsulation of packets, using either EtherType Protocol Discrimination (EPD) or Link Protocol Discrimination (LPD) methods.

Inheritance diagram

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

Implemented by

Name	Type	Description
Ieee80211LlcEpd	simple module	An LLC implementation that encapsulates packets with the IEEE 802 `EtherType` Protocol Discrimination (EPD) header, as defined in section 9.2 `EtherTypes` of the IEEE Std 802-2014 standard. See ~Ieee802EpdHeader.
Ieee80211LlcLpd	simple module	An LLC implementation that encapsulates packets in an LLC header, using IEEE 802 LPD-style encoding.
Ieee80211Portal	simple module	Implements the portal functionality in IEEE 802.11 networks, serving as a bridge between wireless LANs and wired networks. Performs protocol conversion between IEEE 802.11 frames and IEEE 802.3 (Ethernet) frames, handling frame format differences and LLC header management.

Used in compound modules

Name	Type	Description
ExtUpperIeee80211Interface	compound module	Provides an IEEE 802.11 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.
Ieee80211Interface	compound module	Implements an IEEE 802.11 network interface. It implements a large subset of the IEEE 802.11 standard, and may use radio models and wireless signal representations of varying levels of detail. It is also extremely configurable, and its component structure makes it easy to experiment with various details of the protocol.
