Q955 This new RMS architecture worrys me. Without a database like a PMBO, how can messages get through with a 'net failure?

A955 First please try and remember we have been doing this WL2K project about 9 years so we have a pretty good idea of what works and what doesn’t. RMS is not an experiment; it is the natural evolution of what we have learned and optimized over the past 9 years. The RMS concept grew out our experience with PMBOs, central servers and from the successful Telpac effort for packet--hundreds of which have been installed and operated for over 7 years.

The only time an RMS captures or buffers any message will be if it has lost internet connectivity and it has the optional RMS Relay module installed and enabled. (This Module is still being written but the design is functionally complete). RMS relay does have the optional capability to bridge mission critical prioritized messages from local packet users via HF Pactor in the case of no internet connectivity. This allows emergency long haul traffic out of any locally isolated (orphaned) RMS that has Pactor capability. Normally this bridging function would only be enabled during emergency situations due to the limited available bandwidth on HF compared to VHF/UHF. Even if HF bridging does not take place, when connectivity returns buffered messages will flow out to the CMSs and waiting messages for the RMS users will flow in to be available on an RF connection.
