Tier 2 Network
the summer of 2000, when the APRS Internet Service was still in
its infancy, it became apparent that there would need to be a different
approach to how data was delivered. During the next couple of years,
a few server sysops got together and figured out how to apply a
tiered approach to the server configuration. Different software
packages were tried, and finally javAPRSSrvr (by Pete Loveall, AE5PL)
appeared as the most viable piece of APRS server software.
In addition to a tiered setup in which "core" Tier 1 servers
would serve "secondary" Tier 2 servers which in turn would
serve end-users, the filtered-feed port 14580 was created with the
help of javAPRSFilter written by Roger Bille, SM5NRK. In July 2003,
the aprs2.net domain was registered, and the APRS Tier2 Network
was born with five servers in the second tier. The service quickly
grew in demand, and more servers were added as needed.
Though our approach has changed and adapted through the years, the
Tier2 service remains committed to providing top-quality internet
service to all APRS clients worldwide.
The T2 network now offers a user/load balancing system to ensure
the most efficient use of the T2 servers. This in turn means that
in the case of any server outages users are redistributed amoungst
the other T2 servers.
Contrary to belief the majority of our servers are based in Data
Centers with redundant power and feeds. There are strict guidlines
for becoming a T2 Server Sysop ensuring the best quality of servers
The network has its own cross-connected backbone between the T2HUBS.
