Why Self-Management

• Characteristics of Pervasive Computing and
  Ubiquitous Communications
• Many elements of many types
• Heterogeneous communication capabilities
• Heterogeneous computing capabilities
• Various types and sizes of providers (private vs
  multi-national providers)
• Problems
• Affordability
• Scalability
• Ease of use

Self-Management Concepts (1)

• Network Composition
• Built a network out of the various elements and
  networks (unified communication facility)
• Collaboration and fast setup of networks over
  various operators
• Networks using various fixed and wireless
  technologies
• Reconfigurability
• Adaptation of networks and services to the
  current capabilities of the network
• Adaptation of the elements to the current context
  and environment

Self-Management Concepts (2)

• Self-Healing (Fault-Management)
• Automatic detection, localization, and repair
• Closed-Loop Control
• Mainly used for network optimization
• Runs in limited scope (potentially per-element)
• Usage of control theory for networking (problem
  of the number of variables)
• Self-Configuration
• Plug and play
• Enable more affordable and simpler deployment
  (reduction of OPEX)

EU IST Ambient Network

• European Research Project
• Large number of partners including all major
  mobile equipment vendors
• Objectives
• An Ambient Network is a pervasive, reliable
  communication environment hiding the
  heterogeneous infrastructures, supporting the
  ever changing needs of users and services.
• make the always-best-connected dream an
  affordable reality for billions of users
