MessageDispatcher

simple module

This module connects multiple applications, protocols and interfaces with each other and automatically dispatches messages and packets between them. It allows many different configurations from layered architectures where message dispatchers separate different communication layers to centralized architectures where a single message dispatcher is connected to all components.

Configuring the dispatch mechanism:

protocols must register by calling registerService and/or registerProtocol
interfaces must register by calling registerInterface
sockets must register by sending socket messages
packets must have tags attached which specifie the destination protocol, interface or socket

Used in compound modules

Name	Type	Description
AccessPoint	compound module	A generic access point supporting multiple wireless radios, and multiple ethernet ports. The type of the ethernet MAC, relay unit and wireless card can be specified as parameters.
ApplicationLayerNodeBase	compound module	(no description)
EtherHost	compound module	An example host with one Ethernet port and a traffic generator that generates request-reply traffic directly over Ethernet. This host model does not contain higher layer protocols (IP, TCP). By default it is configured to use half-duplex MAC (CSMA/CD).
EtherSwitch	compound module	Model of an Ethernet switch.
ExtUpperIpv4NetworkLayer	compound module	(no description)
Ipv4NetworkLayer	compound module	Network layer of an IPv4 node.
Ipv6NetworkLayer	compound module	Represents an IPv6 network layer (L3).
LdpMplsRouter	compound module	An LDP-capable router.
NetworkLayerNodeBase	compound module	(no description)
NextHopNetworkLayer	compound module	This module provides a network layer for the next hop forwarding.
RsvpMplsRouter	compound module	An RSVP-TE capable router.
SimpleNetworkLayer	compound module	This module provides a simple network layer.
TcpServerApp	compound module	This module is a generic TCP server application with a TCP server listener that creates TCP server connections.
TransportLayerNodeBase	compound module	(no description)
WiseRouteNetworkLayer	compound module	This module provides a simple network layer.
