Detailed Description

The DtForwarderNode class defines a 3-way message distribution architecture for building forwarding networks of arbitrary complexity.

The DtForwarderNode has 3 interfaces: IN: - incoming message path from other DtForwarderNodes OUT: - outgoing message path to other DtForwarderNodes LAN: - bidirectional message path to/from local message sources/sinks ( generally HLA Federates )

• these are the message distribution endpoints

Forwarding Pathways: 1) Messages from LAN will be forwarded out to upstream/downstream forwarders in hierarchical configurations, to the portal forwarders in foreign Forwarder Groups, and to other LAN connections 2) Messages from IN will be forwarded out to LAN 3) Messages from IN can ONLY be forwarded out to OUT under the following conditions: (a) The forwarder is acting as a bridge (aka "link") node between upstream forwarders and downstream forwarders in a hierarchical network. In this case the user must configure the route and specify the endpoints and the bridge forwarder. This will create an entry in the DtRouteMap myRoutesByLinkAddrMap map. Messages can be forwarded FROM upstream sources TO downstream recipients and vice-versa. (b) The forwarder is acting as a portal forwarder in a Forwarder Group. Only certain internal messages will be forwarded, and only FROM foreign Forwarder Groups TO members of the local group, not in the reverse direction. The reverse direction is taken care of by virtue of the fact that all the local group members will have a connection to a portal in the foreign Forwarder Groups so the messages do not need to pass through the local portal. Some messages require the local portal to aggregate responses of the local group members, but the group members individual response messages are not forwarded in those cases.

Note: These pathways do not guarantee that a message will be forwarded as described above. Outlets may be altered by filters and destinations can be added or removed based on the type of message and the network topology. An optional filter may be applied to all messages forwarded to OUT to allow a final message processing step before passing the message.
