1.5.2 SLE SERVICE DOCUMENTATION TREE
The SLE suite of Recommended Standards is based on the cross support model defined in the SLE Reference Model (reference [1]). The services defined by the reference model constitute one of the three types of Cross Support Services:
a) Part 1: SLE Services;
b) Part 2: Ground Domain Services; and
c) Part 3: Ground Communications Services.
The SLE services are further divided into SLE service management and SLE transfer services.
The basic organization of the SLE services and SLE documentation is shown in figure 1-1.
The various documents are described in the following paragraphs.
a) Cross Support Reference Model—Part 1: Space Link Extension Services, a Recommended Standard that defines the framework and terminology for the specification of SLE services.
b) Cross Support Concept—Part 1: Space Link Extension Services, a Report introducing the concepts of cross support and the SLE services.
c) Space Link Extension Services—Executive Summary, an Administrative Report providing an overview of Space Link Extension (SLE) Services. It is designed to assist readers with their review of existing and future SLE documentation.
d) Forward SLE Service Specifications, a set of Recommended Standards that provide specifications of all forward link SLE services.
e) Return SLE Service Specifications, a set of Recommended Standards that provide specifications of all return link SLE services.
f) Internet Protocol for Transfer Services, a Recommended Standard providing the specification of the wire protocol used for SLE transfer services.
g) SLE Service Management Specifications, a set of Recommended Standards that establish the basis of SLE service management.
h) Application Program Interface for Transfer Services—Core Specification, a Recommended Practice document specifying the generic part of the API for SLE transfer services.
i) Application Program Interface for Transfer Services—Summary of Concept and Rationale, a Report describing the concept and rationale for specification and implementation of a Application Program Interface for SLE Transfer Services.
j) Application Program Interface for Return Services, a set of Recommended Practice documents specifying the service type-specific extensions of the API for return link SLE services.
