Apparently, Icom knows about making radio's, but not about creating resilient, load-balanced networks, or they would not have chosen a 'trust server' system consisting of a single instance.
After roughly 20 years of global networking, I can see no justification for this. It should be at least one instance per continent, and then spreading out into child nodes per country or even region, depending on load and local rules and regulations. Also, the system should not require fixed IP addresses, as most people in many countries do not easily get those, and, IF they do, it costs. Rather, the system should implement secure-DNS updates, a bit similar to what SIP trunks do. Only with a well-designed trust network you can create a real 'push the PTT and don't worry' network.. --fred ________________________________ From: dstar_digital@yahoogroups.com [mailto:dstar_digi...@yahoogroups.com] On Behalf Of dlake02 Sent: Friday, July 24, 2009 9:52 AM To: dstar_digital@yahoogroups.com Subject: [DSTAR_DIGITAL] Re: First home-made dstar G2 gateway went live today. > There is a certain expectation among D-STAR RF users that if they are > in range of a D-STAR repeater, that provides gateway services, that > they should be able to do callsign routing to any other D-STAR RF user > that is in range of a gateway equipped D-STAR repeater.
