## Specific Design Goals and Requirements

**A standard Linux server environment** for hosting applications, meaning that
web applications and most daemons (eg, appropriate to run on a single VPS) do
not have to be specifically re-ported to run on rooter.

**Simultaneous 200Mbps down, 109Mbps up routed ethernet throughput** between
local and remote ports. This performance ensures that rooter would not limit
the performance of [DOCSIS 3.0](https://en.wikipedia.org/wiki/DOCSIS#Speed_tables)
cable modem connections.

**"No-surprises" generic router functionality**, meaning that the device should
meet the expectations of non-technical users in it's default configuration:
standard firewall configuration, DHCP and DNS auto-configuration, support for
common upstream authentication mechanisms, configuration via a web interface at
the gateway's IP address.

**Hardware Hackability**, a vague concept. In this case meaning (at a minimum)
that new firmware can loaded and debugged on the device, and that low-level
electronics can be integrated using standard connections (3.3/5v GPIOs, UARTS,
SPI, ADCs, etc).

Ability to **participate in alternative networks** like wireless mesh networks
(BATMAN, OLSR, etc), darknets (i2p), or Tor without excessive difficulty. This
may require some network-specific porting and may contra-indicate some other 

**"Line-rate" WiFi routed throughput** (to local or upstream ethernet ports).
For 802.11n this means 150Mbps for a single 40MHz channel.

**IPv6 fully supported out-of-the-box.**

**"No-reboot" reliability** under defaults with "normal usage", meaning that end
users should never have to manually power cycle the device to resolve local or
uplink DHCP or routing connectivity issues.

**No NDAs, special vendor deals, or binary blobs.** A mostly free/libre
software and hardware stack, reproducable by anybody with capital and
manufacturing facilities.

**"Internet-of-Things" connectivity** via a low-power IP-based wireless
protocol (eg 802.15.4 6lowpan, ZigBee, Bluetooth Low-Energy, etc).

## Hardware features

See [design/hardware]() for specific components and costs.

- 1GHz dual-core ARM SoC processor
- 512MB RAM
- Internal uSD card storage, expandable through SATA and USB ports
- Modular WiFI via miniPCIe slot; recommend dual-band 802.11n
- 2 powered USB ports for expansion
- 5x Gigabit ethernet ports: 4x local + 1x upstream
- Serial and JTAG debugging via micro-USB port
- Low-bandwidth "internet of things" gateway with 802.15.4 radio 
- Hardware entropy generation device

## Comparison

See [research/devices]() for a listing of other similar hardware devices.

**Router?** indicates whether the device meets contemporary first world user
expectations of a home router.

**Server?** indicates whether the devices meets expectations of web application
developers: eg, whether a Ruby On Rails web application would run well enough
for a small group of users.

**Libre?** indicates whether the design of the entire device is truely Free.

**Hack?** indicates whether the device could be integrated into an electronics
project by an Arduino-experienced hacker.
