INetworkLayer2CellularNic

module interface

The INetworkLayer2CellularNic module interface serves as an intermediary between the network layer and the cellular (LTE/NR) protocol stack. It facilitates interactions between the cellular stack and the network layer, enabling the transmission of IP packets through the protocol layers of LTE and NR technologies.

Inheritance diagram

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

Implemented by

Name	Type	Description
IP2Nic	simple module	The IP2Nic module acts as a bridge between the IP network layer and the cellular (LTE/NR) protocol stack. It exhibits slightly different behavior when operating in the UE compared to the BS. Its main functionalities include:

Used in compound modules

Name	Type	Description
LteNicBase	compound module	The LteNicBase module serves as the foundational building block for LTE networking in Simu5G. It integrates protocols for LTE communication, including PDCP, RLC, MAC, and PHY layers. This base module allows higher-level modules, such as User Equipment (UE) and eNodeB (evolved Node B), to configure and utilize these layers according to their specific requirements.

Parameters

Name	Type	Default value	Description
nodeType	string
interfaceTableModule	string
routingTableModule	string

Properties

Name	Value	Description
display	i=block/layer
