Overview
ISO/IEC 10747:1994/Amd 1:1996 is an amendment to the ISO/IEC 10747 International Standard that governs the Protocol for exchange of inter-domain routeing information among intermediate systems to support forwarding of ISO 8473 PDUs. Amendment 1 adds formal Implementation Conformance Statement (ICS) proformas - structured templates suppliers must complete to declare and prove conformance for management information and related OSI management roles.
Key topics and requirements
- Scope of the amendment: introduces normative annexes (Annexes L, M, N and O) that provide proformas for management conformance statements:
- MCS (Management Conformance Summary) - Annex L
- MICS (Management Information Conformance Statement) - Annex M
- MOCS (Managed Object Conformance Statement) - Annex N
- MRCS (Managed Relationship Conformance Statement) - Annex O
- Conformance structure:
- Conformance is split into protocol implementation (subclause 12.1) and management information implementation (subclause 12.2). These are independent.
- Static conformance: supplier must declare manager and/or agent role support and meet minimum requirements for those roles.
- Dynamic conformance: implementations claiming dynamic conformance must support specified procedures and semantic elements for items claimed.
- Role-specific requirements:
- Manager role: must implement at least one management operation, notification or action on the managed objects specified by the standard (tables referenced in Annex L).
- Agent role: must support one or more instances of the IDRP config managed object and the Adjacent BIS managed object and at least one name binding per supported managed object.
- Proforma rules: Any MCS/MICS/MOCS/MRCS must be technically identical to the proformas in the annexes - preserving table numbering and index items (pagination/headers may differ).
- Technical references:
- ASN.1 / BER transfer syntax required for referenced abstract data types: joint-iso-ccitt asn1(1) basicEncoding(1) (ISO/IEC 8825).
- Conformance testing and ICS guidance reference ISO/IEC 9646 series and ITU-T/ISO guidance (X.724 / ISO/IEC 10165-6, X.291, X.296).
Applications and who uses it
- Network equipment vendors implementing inter-domain routing protocols for OSI-based networks (IDRP / ISO 8473).
- Software developers building protocol stacks, management agents or network management systems that must declare conformance.
- Test labs and certification bodies performing conformance testing and interoperability assessments.
- Network architects and operations teams who need precise conformance documentation for procurement, integration and compliance.
