A3 architecture

Intro

The A3 architecture divides the Assothink work in 3 layers

• computing layer
• server layer
• monitoring layer

Computing layer

This layer runs the Assothink brain(s).

Only concepts, links, signals.

Operated as client of a centralized server, but continues to run autonomously if the server does nor answer.

A brain uses a brain slot: a host/port combination.

Many brains run at the same time in a network, or even on a machine.

Suggested hardware

standard PC

mainly accessible trough network (remote shells)

with Linux OS and JVM

with strong processor, gigabit ethernet

4 Gb RAM, USB port, small HD, simple graphic controller

without (no need) CD/DVD, advanced graphic, monitor, keyboard, mouse...

Server layer

This layer controls, starts, stops the brains ; sends them signal input ; receives their state (excitation levels, stats)

One server per network.

Includes a socket server for the brain(s).

Includes a socket server for the monitor server side.

Suggested hardware

Same as computing layer

Monitoring layer

Includes a GWT (tomcat) server side and a GWT front-end client applic running in browsers.

One server occurence.

Many clients.

No specific hardware needed.

The client is similar to the client in the basic architecture.
