OSI Systems Management, Internet SNMP and ODP/OMG CORBA as Technologies for Telecommunications Network Management
George Pavlou · 1999
Syntax Notation 1 (ASN.1) [X208] language. This is an abstract "network" data structuring language that supports simple and constructed types. A particularly important ASN.1 type is the Object Identifier (OID), which expresses a sequence of nonnegative integers on a global registration tree. OIDs are registered by standards bodies, for example ISO, ITUT and IETF, and are used instead of friendly string names to avoid ambiguities. For example, the OSI objectClass attribute name is registered as {joint-iso-ccitt(2) ms(9) smi(3) part2(2) attribute(7) objectClass(65)}. ASN.1 is used in both the OSI management and SNMP frameworks to specify the management protocol packets and the structure of managed object information, for example attributes, operation parameters / results and notification information.
