Name Type Description
LinkLayerNodeBase compound module (no description)

Known subclasses

Name Type Description
InternetCloud compound module

This module is an IPv4 router that can delay or drop packets (while retaining their order) based on which interface card the packet arrived on and on which interface it is leaving the cloud. The delayer module is replaceable.
