Introduction Facilities layer entities that use the Basic Transport Protocol for the transport of messages need to be identifiable. For this purpose, BTP defines port numbers. The present document specifies the well
15、-known port numbers to be used by facilities layer entities. ETSI ETSI TS 103 248 V1.1.1 (2016-11)5 1 Scope The present document defines port number values for the Basic Transport Protocol as specified in ETSI EN 302 636-5-1 i.1. 2 References 2.1 Normative references References are either specific (
16、identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies.

24、: destination port: port identifying the destinations protocol entity at the ITS facilities layer NOTE: Facilities layer services that do not expect replies either do not include a source port number in the header, or they set it to a default (usually 0) to indicate no reply port available. For sess
25、ion-based services (client-server or peer-to-peer), the source port is often set to a value from an ephemeral (dynamically assigned) subspace of the space of all port numbers. port: ITS station-internal address that identifies a protocol entity at the facilities layer and represents an endpoint of a
26、 logical connection source port: port number to be used by an facilities layer entity as the destination port in a subsequent reply to the originator 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ASN.1 Abstract Syntax Notation One BTP Basic Transport
