3.1

IoT management service entity

IoT MSE

collection of modules required for a specific instantiation of 6LoWPAN

Note 1 to entry: The 6LoWPAN network comprises of a set of 6LoWPAN protocols, of which some are already standardized (see IETF RFC 6282and IETF RFC 6775, etc.).

3.2

6LoWPAN address

address including the network prefix and the host address

Note 1 to entry: The network-prefix set-up determines if the device can be addressed globally whereas the host address should be unique within the 6LoWPAN.

3.3

6LoWPAN prefix

prefix corresponding to a node's address

3.4

link-local address

6LoWPAN address corresponding to a “link-local 6LoWPAN unicast address” and being used to communicate with devices in the same PAN

3.5

6LoWPAN global address

6LoWPAN address for communicating with devices globally

3.6

6LoWPAN node

device that implements 6LoWPAN

Note 1 to entry: See IETF RFC 4944, IETF RFC 6282 and IETF RFC 6775.

3.7

6LoWPAN host

ITS-S 6LoWPAN node comprising of ITS-S IoT MSE functionality other than those of a 6LoWPAN router or 6LoWPAN gateway

3.8

6LoWPAN internal interface

interface of a 6LoWPAN node in an ITS station used to connect with other 6LoWPAN nodes

3.9

6LoWPAN external interface

6LoWPAN interface of an ITS-S 6LoWPAN router node in an ITS station used to connect to the Internet or to other ITS-Stations

3.10

6LoWPAN ad-hoc router

device that implements 6LoWPAN and a layer-3 ad-hoc routing protocol internally to an ITS-S

Note 1 to entry: IETF RFC 4944, IETF RFC 6282, and IETF RFC 6775.

3.11

6LoWPAN access router

6LoWPAN AR

6LoWPAN router residing in an ITS-S at the edge of an Access Network and connected to one or more access points

3.12

6LoWPAN-IPv6 border router

6LoWPAN-IPv6 BR

6LoWPAN router residing in an ITS-S at the edge of an Access Network and connected to the Internet

Note 1 to entry: This router could perform additional functions related to IPv6 networking as defined in ISO 21210.

3.13

ITS-station unit

ITS-SU

physical instantiation of an ITS-S

Note 1 to entry: This could be a distributed instantiation in a 6LoWPAN/IPv6 Border router and 6LoWPAN Hosts. An ITS-SU contains one or more ITS-SCUs, and hence one or more communication interfaces (CIs). See Annex A for guidelines on CI.

3.14

ITS-S communication unit

ITS-S CU

physical unit in an ITS-SU containing a part or all of the functionality of an ITS-S

Note 1 to entry: In case an ITS-SU consists of a single physical unit, the ITS-SU and the ITS-SCU are identical. In case an ITS-SU consists of more than one ITS-SCU, then these ITS-SCUs are interconnected via the ITS station-internal network of the ITS-SU.
