Overview l.jpg

Overview

Project

  • New cognitive architecture to address self-healing and self-defense in distributed networks

  • Will require advances in representation and reasoning, communications and interaction technology, computational perception, and learning

  • Begin with LAN problem testbed; later transition to other RAP applications


Areas of research innovation l.jpg

Areas of Research Innovation

  • Partially observable Markov decision processes

  • Distributed diagnosis and repair using coalition logic and game theory

  • Hierarchical distribution of intelligence

  • Adaptation and learning


Technical rationale l.jpg

Technical Rationale

Critical need for distributed cognitive networks

  • Operating with or without a centralized command node

  • Each node having knowledge of overall network and goals

  • Cognitive hierarchy functioning at individual node level, collaborating with neighboring nodes, and with global coordination and learning

  • Adaptive knowledge, building on individual and collaborative experience


Technical rationale continued l.jpg

Technical Rationale (continued)

LAN problem ideal for study

  • Well-defined problem; can be specified using only commercial components.

  • Complex – currently requires extensive human expertise

  • System is inherently distributed and amenable to solutions based on coalitions or teams of agents

  • System is subject to unpredictable changes in connectivity, hardware, firmware, and software at any time in any of its components

  • Connectivity of the system is unreliable, especially for wireless networks

Network Self-Healing, Self-Defense

Corrective Response

  • Communicate experience for diagnosis and repair

  • Update experience base with feedback

Web Server Attack

Collaboration

Bus

  • Identify source

  • Request assistance from firewall

Network Application

Failure

  • Identify incorrect/incompatible settings, consulting with neighboring nodes

  • Adjust local settings

  • Request network settings adjustment from routing node


A hard problem l.jpg

A Hard Problem

The problem of distributed cognition is hard, and not yet tested in real-world domains. This will be the first application to combine

  • Extensive formal representation of network states

  • Partitioned and hierarchical intelligence

  • Coalition reasoning

  • Adaptive distributed knowledge base
