= Architecture =

HERMES architecture is based on a software-defined HF transceiver setup (currently sBitx is the main target, but should work with any HF transceiver). HERMES has an easy to use Web-based graphical user-interface, which provides access to to radio control parameters, UUCP queue management, call scheduling, messaging system, email management and other administrative tasks.

Apart of the hardware, the main components are (from bottom to top in the network layers):

* Modem: Works with VARA, Ardop or Mercury. Mercury at https://github.com/Rhizomatica/mercury
* UUCP: HERMES default transport protocol is UUCP, used as available in Debian / RaspiOS uucp package
* HERMES API: PHP API backend https://github.com/Rhizomatica/hermes-api
* HERMES GUI: Web-based web interface: https://github.com/Rhizomatica/hermes-gui
* HERMES NET: A set of network subsystems. Includes UUCP <-> Modem bridge solution (uucpd), control software with websockets communication (eg. trx_v2-userland), email compression / transcoding solutions (uuxcomp) and many scripts for uucp management, source compression and others: https://github.com/Rhizomatica/hermes-net
* Email stack: UUCP is used together with Postfix, Dovecot and other email software stack for providing a complete email solution with special compression of image and audio attachments.
