Motivation

  • Studying Aeronautical communications in a Multilink environment
  • Evaluating the impact of communication protocols in terms of:
  • System overhead (number of additional messages)
  • System load (computation at critical nodes, storage capacity)
  • Extensible to:
  • Multiple DataLinks
  • Multiple Applications and Communication Services

Conclusions and Future Work

  • SAPIENT + LISP: system-level simulator for FCI and Multilink
  • Arbitrarily increase the complexity of domains, keeping the same

Router Architecture

  • Evaluation of the system LOAD
  • Move everything to IPv6
  • Testing using realistic traffic models and mobility patterns
