Compound Module SubHost

Package: pubsub_sim
File: src/SubHost.ned

The Subscriber Host

This is the subscriber host for the publish subscribe simulation. This host only has a MAC and an application layer. No IP or other network layer protocol is involved. Multiple application can be used, but each will use a different ethernet interface, therefore, it will be characterized by a different FID. This host is only capable of subscribing to Information Items, and receives packets which are afterwards treated as in a sink.The InterfaceTable, the FwTable and the NotificationBoard modules are present in order for the LinkMon module to access the necessary information, needed by the TM.
