L2NodeConfigurator

Package: inet.linklayer.configurator

L2NodeConfigurator

simple module

This module has one instance per network node, and it acts like a bridge between the node and the network's global configurator module, L2NetworkConfigurator.

L2NetworkConfigurator only computes and remembers configuration data (port priority, link cost, etc.), but doesn't configure the nodes' routing tables and interfaces accordingly. The actual configuration is carried out by this module, at network initialization time and also when the node restarts (i.e. after a shutdown or a crash.)

This module is needed because of failure/restart scenarios: L2NetworkConfigurator would not be able to configure the node after a restart, because being a global module, it doesn't know about node lifecycle events.

L2NodeConfigurator

Used in compound modules
