What is SC INET?

A “social network” of humans & devices

Complex scenarios over collaborative

logic

Ecosystem of collaborative

agents Self-organizing

Easy to program logic

SC NET Triad

• The SCAINET Triad consists of three basic agent elements:• The Base agent• The Gateway agent• The Fusion agent

• It is the core component of SCAINET, used to connect devices and humans in the context of a well defined (and scope-space limited) group

• It is also used for 2nd level (cross Triad) communication between agents

• Finally, it provides the entry point for logic fusion and agent programming

• Acts as a hub within each Triad, supporting the communication between agents

• Each new agent can:• Discover other agents• Announce its presence• Publish, Subscribe to information to/from

other agents through the Base agent

Base gent

• Responsible for fusion of logic into the system

• Provides two types of interfaces • A simple, If This, Then Need/Will Do That interface (suitable for simple users, and using a web front end)• An API for directly programming logic

into a Triad

Fusion gent

• Responsible for interconnecting Triad minisystems

• Acts as a gateway to the SCAINET ecosystem, able to:• Collect and introduce external information

and events to a Triad minisystem• Publish – export information from a Triad

minisystem to the SCAINET ecosystem

• Acts also as a tunneling point between Triads, allowing them to form links at a higher level than this of agents

Gateway gent

• Acts as the intermediate between a device and a Triad minisystem

• Contains:• Logic • List of needs (what agent understands)• List of (done) actions (what agent senses)• List of reports (what agent reports)• List of (do) actions (what agent/device does)

• Can even operate without a connected device

Implementing SC INET

• Running on OpenStack:• Virtualized hardware (openstack-nova // amazon-EC2)• Virtualized networking (openstack-neutron // amazon VPC)• Virtualized storage (openstack-swift // amazon-S3)

• Able to run automated tasks like processing, storage and bandwidth tuning, based on demand

• Self hosted and Open Source

Implementing SC INET

• Traffic from agent middleware comes from the internet

• The edge router forwards it to the SCAINET Agent Router VMs, acting as a Message Bus and authentication gateway

• SCAINETVMs take messages from the bus and process them

Message bus

AgentName: [Intention] action(val), [IN location], [AT time], [AND (attr:value)]
