IEC 62541-5:2020OPC Unified Architecture - Part 5: Information Model

IEC 62541-5:2020 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62541-5:2020 defines the Information Model of the OPC Unified Architecture. The Information Model describes standardized Nodes of a Server's AddressSpace. These Nodes are standardized types as well as standardized instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not expected that all Servers will provide all of these Nodes. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Added Annex F on User Authentication. Describes the Role Information Model that also allows configuration of Roles. b) Added new data types: "Union", "Decimal", "OptionSet", "DateString", "TimeString", "DurationString", NormalizedString", "DecimalString", and "AudioDataType". c) Added Method to request a state change in a Server. d) Added Method to set Subscription to persistent mode. e) Added Method to request resending of data from a Subscription. f) Added concept allowing to temporarily create a file to write to or read from a server in C.4. g) Added new Variable type to support Selection Lists. h) Added optional properties to FiniteStateMachineType to expose currently available states and transitions. i) Added UrisVersion Property to ServerType. This version information can be used for session-less service invocation.

Network Functions Virtualisation (NFV) Release 2; Management and Orchestration; Or-Vnfm reference point - Interface and Information Model Specification

The present document specifies the interfaces supported over the Or-Vnfm reference point of the Network Functions Virtualisation Management and Orchestration (NFV-MANO) architectural framework ETSI GS NFV-MAN 001 as well as the information elements exchanged over those interfaces.

ETSI GS NFV-IFA 007 V2.7.1

Network Functions Virtualisation (NFV) Release 3; Management and Orchestration; Or-Vnfm reference point - Interface and Information Model Specification

The present document specifies the interfaces supported over the Or-Vnfm reference point of the Network Functions Virtualisation Management and Orchestration (NFV-MANO) architectural framework ETSI GS NFV-MAN 001 as well as the information elements exchanged over those interfaces.

ETSI GS NFV-IFA 007 V3.3.1

Network Functions Virtualisation (NFV) Release 2; Acceleration Technologies; Management Aspects Specification

The present document specifies functional requirements for both the Virtualised Infrastructure Manager (VIM) and the NFV Infrastructure (NFVI), for NFV acceleration from an infrastructure management perspective. This includes the controlling and management of acceleration resources, e.g. allocation, release and discovery of acceleration resources. The present document also identifies the corresponding impacts on VIM related specifications regarding functional requirements ETSI GS NFV-IFA 010 and reference points (ETSI GS NFV-IFA 005 and ETSI GS NFV-IFA 006).

ETSI GS NFV-IFA 004 V2.4.1

Network Functions Virtualisation (NFV) Release 2; Acceleration Technologies; vSwitch Benchmarking and Acceleration Specification

The present document specifies performance benchmarking metrics for virtual switching, with the goal that the metrics will adequately quantify performance gains achieved through virtual switch acceleration conforming to the associated requirements specified herein. The acceleration-related requirements will be applicable to common virtual switching functions across usage models such as packet delivery into VNFs, network overlay and tunnel termination, stateful Network Address Translators (NAT), service chaining, load balancing and, in general, match-action based policies/flows applied to traffic going to/from the VMs. The present document will also provide deployment scenarios with applicability to multiple vendor implementations and recommendations for follow-on proof of concept activities.

ETSI GS NFV-IFA 003 V2.4.1

Network Functions Virtualisation (NFV); Virtualisation Technologies; Hypervisor Domain Requirements specification; Release 3

The present document provides requirements for the hypervisor domain as it pertains to an operator's network. It focuses on gaps between Network Functions Virtualisation (NFV) use cases and the industry state of art at the time of publication. Therefore requirements that are deemed to be supported by most hypervisor solutions at the time of publication are not repeated in the present document.

ETSI GS NFV-EVE 001 V3.1.1

Network Functions Virtualisation (NFV) Release 3; Reliability; Maintaining Service Availability and Continuity Upon Software Modification

The present document specifies requirements for the purpose of Software Modifications, such that NFV service availability and continuity is maintained. All types of software related to Network Function Virtualisation (NFV) - e.g. Virtual Network Functions (VNF), Management and Orchestration (MANO) and Network Function Virtualisation Infrastructure (NFVI) as well as required controlling and supporting functionality will be addressed. Where applicable, external specifications may be referenced to avoid duplication of work. The present document contains normative provisions.
