INetworkLayerUpper¶

module interface INetworkLayerUpper

Interface for different network layers.

Inheritance diagram¶

Implemented by¶

Name	Type	Description
ExtLowerIpv4NetworkLayer	compound module	Provides a simplified network layer for emulation that connects the simulation to a real network on the host computer. Uses ExtLowerIpv4 to send packets from the simulation to the real network and receive packets from the real network into the simulation using raw sockets.
ExtUpperIpv4NetworkLayer	compound module	Provides a network layer that connects the simulation to a real network on the host computer using a TUN device. Allows simulated applications to send and receive packets through the host’s networking stack at the IP layer. Contains standard components like routing table and ARP, and uses ExtUpperIpv4 with a TUN device for external connectivity.
SimpleNetworkLayer	compound module	Provides a simple network layer.
Ipv4NetworkLayer	compound module	Network layer of an IPv4 node.
Ipv6NetworkLayer	compound module	Represents a complete IPv6 network layer (L3), to be used within hosts and routers. It connects to higher-layer protocols (TCP, UDP, …) on top and to the network interfaces below, and bundles the modules that together implement IPv6:
NextHopNetworkLayer	compound module	Provides a network layer for the next hop forwarding.
WiseRouteNetworkLayer	compound module	Provides a simple network layer.
