1 1 ICAO ACP WG-N meeting Use of IP in ARTAS 3 rd July 2006 European Organisation for the Safety of Air Navigation

2 2 ARTAS ARTAS (ATM Radar Tracker and Server) is conceived as a distributed system composed of a number of identical sub- systems, each with their own domain of Operation, co- operating together. Each sub-system, called an ARTAS Unit, will process all surveillance data reports - at present, these are classical radar reports and, in the future, Mode S and ADS reports as well - so as to form the best estimate of the current air traffic situation.

11 11 Router Bridge ARTAS System presentation (contd) The Router Bridge is the only OP CSCI interfacing with the external world. The RBR can use up to 6 LANs. Only the first 2 can be used for Sensor Input. Max 23 USER simultaneously ( 20 Ordinary Users and 3 Adjacent Units or 12 Adjacent Units and 11 Ordinary Users) Point-to-Point USER LAN SUPERVISION LAN RADAR LAN B RADAR LAN A BROADCAST LAN NTP LAN

12 12 Protocols used in ARTAS TCP: The RFC 793 IP: RFC 761 Multicast Host Extensions for IP multi-casting: RFC 1112 UDP: RFC 768 PDC (Private Data Channel) NTP: RFC 1305 SNMP: RFC1157

13 13 SENSOR INPUT ARTAS supports up two RADAR LANs. Secondary LAN Preferred LAN FDDI (except with V7A1 Linux) and Ethernet LANs are supported.

14 14 SENSOR INPUT Sensor information is a multicast message. There are two possible protocol stacks: Only one protocol stack has to be used. ETHERNET or FDDI MAC/LLC1 ASTERIX ÌP UDP ETHERNET or FDDI MAC/LLC1 ASTERIX UDP/IP MAC/LLC1

24 24 IPAX Compliance: A destination port uniquely identifies the application in the receiving system that should process the incoming IP packets. ARTAS Requirement: There shall be a default port number* (configurable by means of an MMS parameter) that is written initially to the fields Port 1 to Port 4. For backwards compatibility an operator can choose to change this default port number according to his needs (in the range of [1024, 65535]). Implementation: A sensor is not any longer identified by a PORT NUMBER and there is DEFAULT PORT NUMBER for ALL RADARS. * The default port number would be the port number for ASTERIX in receiving systems. IPAX COMPLIANCE

25 25 RADAR DEFINITION

26 26 RADAR IDENTIFICATION SIC/SAC Alias of the SIC/SAC; Route preferred and Route secondary Preferred LAN and Secondary LAN * 4 Channels * The input coming from the secondary LAN is always received by ARTAS.

27 27 RADAR IDENTIFICATION Channels definition Channel #1 = ( Preferred LAN, preferred route ); MULTICAST IP 1; PORT 1 Channel #2 = ( Preferred LAN, secondary route ); MULTICAST IP 2; PORT 2 Channel #3 = (Secondary LAN, preferred route ); MULTICAST IP 3; PORT 3 Channel #4 = (Secondary LAN, secondary route); MULTICAST IP 4; PORT 4 The list order defines the priority amongst the four channels. In ARTAS there is a mechanism that will always select the highest priority channel amongst those available.

28 28 ARTAS non-Sensors Environment Unique IP PORT NUMBER for the output. At the moment the UDP ports must be in the range [5001,65535]

29 29 IPv6 ARTAS is only validate for IPV4.
