ASN.1 is a data type declaration notation. It does not define how to manipulate a variable of such a type. Manipulation of variables is defined in other languages such as SDL (Specification and Description Language) for executable modeling or TTCN-3 (Testing and Test Control Notation) for conformance testing.
X.690. X.690 is an ITU-T standard specifying several ASN.1 encoding formats: The Basic Encoding Rules (BER) were the original rules laid out by the ASN.1 standard for encoding data into a binary format. The rules, collectively referred to as a transfer syntax in ASN.1 parlance, specify the exact octets (8-bit bytes) used to encode data.
^ ASN.1 has X.681 (Information Object System), X.682 (Constraints), and X.683 (Parameterization) that allow for the precise specification of open types where the types of values can be identified by integers, by OIDs, etc. OIDs are a standard format for globally unique identifiers, as well as a standard notation ("absolute reference") for ...
Asymmetric numeral systems ( ANS) [1] [2] is a family of entropy encoding methods introduced by Jarosław (Jarek) Duda [3] from Jagiellonian University, used in data compression since 2014 [4] due to improved performance compared to previous methods. [5] ANS combines the compression ratio of arithmetic coding (which uses a nearly accurate ...
An autonomous system ( AS) is a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators on behalf of a single administrative entity or domain, that presents a common and clearly defined routing policy to the Internet. [ 1] Each AS is assigned an autonomous system number ( ASN ), for use ...
An Amazon Standard Identification Number ( ASIN) is a 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization. [1] They were designed in 1996 by Rebecca Allen, an Amazon software engineer, when it became clear that Amazon was going to sell products other than ...
GeneralizedTime. A GeneralizedTime is a time format in the ASN.1 notation . It consists of a string value representing the calendar date, as defined in ISO 8601, a time of day with an optional fractional seconds element and the optional local time differential factor as defined in ISO 8601.
In computing, the Structure of Management Information (SMI), an adapted subset of ASN.1, is a technical language used in definitions of Simple Network Management Protocol (SNMP) and its extensions to define sets ("modules") of related managed objects in a Management Information Base (MIB). SMI subdivides into three parts: module definitions ...
