h1. Network architecture

The network architecture deployed by the microbox is by default as follows:

Th internet source can be everything at the user's disposal, but it must meet the following requirements:

* outputs as an ethernet RJ45 wire or Wifi (b/g/n/ac)

* implements the MAC protocol

* implements IP protocol.

Those requirements are met most of the time, for instance when we consider a residential landline, a public

wifi hotspot or a satellite connexion.

One very strong point in the system we've made is the router. We were advised a few routers, and we chose the most recent one.

This one not only offers compatibility with the latest evolution in networking (like the 802.11ac standard), but also offers very advanced configuration options and capabilities.

this is really an asset, as it simply means that if someone with networking skills on the field is present, then the microbox can become very versatile (like maikng a separate network for wired and wireless devices, or bridging to an existing wifi network).

We also have a DHCP sevrer bundled with the router, and we configured it to give leases to every device that successfully connects to the network, except the single board computer, that benefits from a static IP.
