We continue our series of XMPP Performance whitepapers by looking at measurements over HF Radio using STANAG 5066 (a NATO specification for running data applications over HF Radio) and IP. You can find out more about STANAG 5066 here.
HF Radio is an important communications mechanism for many of our target markets. In some situations it is the primary means of achieving beyond line of sight communications, in others it acts as a backup to Satellite Communications. HF Radio is however a very constrained channel with awkward operational characteristics and special protocols need to be employed to achieve useful performance.
In this whitepaper we describe and analyse measurements made operating XMPP over HF Radio, using HF modems and a simulated radio link. Measurements are made operating directly over STANAG 5066 and over IP (using both standard XMPP server to server protocol and Isode’s optimized server to server protocol).
The measurements show that good performance is achieved over HF using STANAG 5066 for a wide range of parameters. Operation over IP over HF gives good results in some situations, but is not generally recommended.
