ITS-ProtStckID (ITS protocol stack identifier):
ITS communication protocols are identified by an OID {iso(1) identified-organization(3) cen(162) cp17496(17496) its-scps(3) its-scps-'n'('n')
ITS protocol stack identifier its-scps-'n' is specified in ASN.1 as ITSprotocolStckID::=INTEGER(0..MAX).
The following ITS protocols stacks are identified and can be referenced by the globally unique ITS-ProtStckID:
| ITS-ProtStckID | Name of protocol stack | Comments |
| 0 | Unknown protocol stack | Reserved to indicate an unknown protocol stack |
| 1 | ITS station-internal management communications secure sessions using Ethernet and IPv6 | See ISO 24102-4 |
| 2 | SCN-access for SCN diagnostic using Ethernet and IPv6 | See CEN/ISO TS 21184 and ISO 22900-2 |
| 3 | General service announcement using ITS-M5 and FNTP | See EN ISO 22418 |
| 4 | General secured sessions involving Internet | |
| 5 | Secure broadcast of messages with ETSI ITS-G5 Release 1 stack | |
| 6 | IPv6 localized communication with IPv6 | |
