Goals of Project

• Implementation of kingdom wide network to serve
  all ANS facilities
• Support ATM and ATC data and voice flows
• Form a single and robust communication
  infrastructure
• Provide redundancy for links and communication
  hardware
• Provide simplicity and scalability of addition of
  applications
• Monitoring communication facilities to identify
  faults

3
Present ANS Communication

• Individual links for each application
• Lack of redundancy at Hardware and link levels
• Addition of application requires new circuits and
  hardware
• Delay of lunching of applications due to
  unavailability of lines

NAN Monitoring

• NAN Monitoring tools provide graphical
  representation of the NAN and allow monitoring
  NAN devices and links
• Monitoring include hardware faults, link status,
  bandwidth utilization and topology changes
• NNMC Located in Jeddah and Riyadh ACCs and will
  supervise the whole NAN.
• RNMT Located in other sectors and Jeddah HQ and
  will monitor sites related to the sector.
