Overview

The Abstract Syntax Notation One (ASN.1) is a notation language that is used for describing structured information that is intended to be transferred across some type of interface or communication medium. It is especially used for defining communication protocols.

SDL is suitable for specifying the semantic actions of a protocol, something that ASN.1 does not cover.

By using ASN.1 data types in the implementation of your application, you will optimize your development process. The following list displays some of the advantages of ASN.1:

The SDL Suite support for ASN.1 consists of two major parts:

You can access the ASN.1 coders from SDL diagrams as well as from the C code.

Before you start the encoding and decoding steps, you must perform some preliminary steps. These are presented in Tutorial: Using ASN.1 Data Types.
