All international ATC data exchange applications such as All international ATC data exchange applications such as OLDI, make use of X.25 technologyOLDI, make use of X.25 technology

Key manufacturers have stoppedKey manufacturers have stoppedselling X.25 equipment and willselling X.25 equipment and will cease support after 2005 cease support after 2005

The Solution is IP :The Solution is IP : IP is omnipresent and matureIP is omnipresent and mature IPv4 is implemented in States; different approachesIPv4 is implemented in States; different approaches IP version 6 is supported by the European Commission (PR IP version 6 is supported by the European Commission (PR
