The Ultra Messaging Dynamic Routing Option (DRO) consists of a daemon called the "UM Router" (or just the DRO) that bridges disjoint Topic Resolution Domains (TRDs) by effectively forwarding control and user traffic between them. Thus, the UM Router facilitates WAN routing where multicast routing capability is absent, possibly due to technical obstacles or enterprise policies. (FYI: a historical name for the UM Router is "Twenty Nine West Gateway Daemon" or "tnwgd". In the documentation you will see various abbreviations that include "tnwg".)
The UM Router includes the following features:
