vMRF High Level Statement of Compliance
Virtual Multimedia Resource Function

Contents


1 General

This document provides general information about compliances with standards for the Virtual Media Resource Function (vMRF). This document includes a listing of standard specifications, RFCs, technical reports, and other specifications applicable to the vMRF.

The Ericsson virtual media resource functionality consists of two main functional structures: Multimedia Resource Function Processor (MRFP) functionality and Multimedia Resource Function Controller (MRFC) + MRFP functionality, as shown illustrated in Figure 1.

The MRFP functionality supports only announcement service and audio conferences. That must be in mind when reading the compliance statements.

This document indicates also the difference to legacy MRF running on Ericsson native hardware:

Standards which are supported by the native MRF, but not yet supported by vMRF are marked with italic text.

Standards which are supported only by vMRF and not in native MRF are marked with bold text.

Note: The MRFC functionality has not been implemented yet.
Figure 1   vMRF Functional Structure Overview

2 Statement of Compliance

Each specification is categorized by one of the following statements:

Compliant (C)  

States that the functionality provided has been implemented according to the standard definition. The High-level SoC summarizes the important exceptions.
Partly Compliant (PC)  

States that some part of the functionality that is provided has been implemented in a way that differs from the standard definition. The High-level SoC summarizes the important exceptions.
Not Compliant (NC)  

States that the functionality that is provided has been implemented in a way that differs from the standard definition.
Not Implemented (NI)  

States that the functionality specified in the standard is not provided at all. Note, that if, for example, a supplementary service standard is listed as "Not Implemented", it also means that sections in other standards covering, for example, interactions with this supplementary service are "Not Implemented". This will however not be visible in the list of limitations for those other standards.
Not Applicable (NA)  

This category is used for the following cases:

  • Descriptive specifications containing no normative requirements for vMRF.

  • Specifications that only put requirements on the terminals.

2.1 ETSI NFV Standards

Generally, the vMRF VNF follows the principles set out in the ETSI NFV standards: http://www.etsi.org/technologies-clusters/technologies/nfv
