(N)-entity-type

A description of a class of (N)-entities in terms of a set of capabilities defined for the (N)-layer.

[ccsds-910.2-G-1]

Details

Provisional

(N)-layer

Any specific layer in a multi-layer protocol stack. The layer above is called the (N+1)-layer, the layer below is called the (N-1)-layer. This notation is also used in the model for other concepts that are related to these layers, for example, (N)-protocol, (N+1)-service.

[ccsds-311.0-M-1]

1.3.112.4.30.7

Details

Provisional

(N)-layer management

Functions related to the management of the (N)-layer partly performed in the (N)-layer itself according to the (N)-protocol of the layer (activities such as activation and error control) and partly performed as a subset of systems management.

[ccsds-910.2-G-1]

1.3.112.4.30.8

Details

Provisional

(N)-layer operation

The monitoring and control of a single instance of communication.

[ccsds-910.2-G-1]

1.3.112.4.30.9

Details

Provisional

(N)-protocol

A set of rules and formats (semantic and syntactic) which determines the communication behavior of (N)-entities in the performance of (N)-functions.

[ccsds-910.2-G-1]

1.3.112.4.30.10

Details

Provisional

(N)-protocol-control-information

Information exchanged between (N)-entities, using an (N-1)-connection, to coordinate their joint operation.

[ccsds-910.2-G-1]

1.3.112.4.30.11

Provisional

(N)-protocol-data-unit

A unit of data specified in an (N)-protocol and consisting of (N)-protocol-control-information and possibly (N)-user data.

[ccsds-910.2-G-1]

1.3.112.4.30.12

Details

Provisional

(N)-service

A capability of the (N)-layer and the layers beneath it, which is provided to (N+1)-entities at the boundary between the (N)-layer and the (N+1)-layer.

[ccsds-910.2-G-1]

1.3.112.4.30.13

Details

Provisional

(N)-service-access-point

the point at which (N)-services are provided by an (N)-entity to an (N+2)-entity.

[ccsds-910.2-G-1]

1.3.112.4.30.14

Details

Provisional

(N)-service-data-unit

an amount of information whose identity is preserved when transferred between peer-(N+1)-entities and which is not interpreted by the supporting (N)-entities.

Provisional

(N)-subsystem

An element in hierarchical division of an open system which interacts directly only with elements in the next higher division or the next lower division of that open system.

[ccsds-910.2-G-1]

1.3.112.4.30.17

Details

Provisional

(N)-user-data

The data transferred between (N)-entities on behalf on the (N+1) entities for whom the (N)-entities are providing services.

1.3.112.4.30.18

Details

Provisional

9/7 DWT

A DWT using a nine-tap filter to obtain low-pass wavelet coefficients and a seven-tap filter to obtain high-pass wavelet coefficients. Two different specific 9/7 Discrete Wavelet Transforms are recommended: 9/7 Float DWT for lossy compression and 9/7 Integer DWT for lossless compression.
