ETSI announce a number of resource management and orchestration enhacements to its NFV specifications for supporting 5G networks.
Specifically, new NFV Release 3 features that closely relate to 5G include:
- Support for network slicing in NFV
- Management over multi-administrative domains, and
- Multi-site network connectivity.
“As a founding partner in 3GPP, ETSI has a major role to play in contributing and aligning specifications and requirements.” says Cristina Badulescu, ETSI ISG NFV Vice-Chair.
ETSI and 3GPP collaboration has been key throughout the specification work of ETSI NFV Release 2 and 3, to ensure interoperability between management systems – covering upper orchestration and management layers, such as network management or application management. The 3GPP-defined management system interacts with ETSI NFV Management and Orchestration (MANO) system to realize the resource management for virtualized Core Network (CN), virtualized Radio Access Network (RAN) and network slicing.
More specifically, in the NFV Release 3, an external touchpoint between the NFV’s Network Service and network slicing was defined – in which the Network Service becomes a composite element of the 3GPP SA5 network slice subnet construct – enabling market implementations to easily combine the 3GPP SA5 Network Resource Model (NRM) with the ETSI NFV Information Model.
ETSI and Linux Foundation agree on Open Source collaboration
The Linux Foundation and ETSI signed a Memorandum of Understanding to bring open source and standards closer and foster synergies between them. Areas of mutual interest include technologies concerning NFV, MANO, AI and edge computing. The collaboration agreement is expected to enable faster information-sharing and deployment of open networking technologies. The organinzations will engage in collaborative activities, joint communication, promotion…
Lean NFV proposes a Key-Value Store to simplify deployments
A new industry initiative known as Lean NFV is aiming to simplify the process of onboarding virtualized network functions (VNFs). Six years after the publication of the first Network Functions Virtualization (NFV) specification, proponents of Lean NFV argue that the technology has failed to live up to its promises largely due to complexity and inefficiency in the deployment model. The topic was addressed in a keynote at last week’s Open Networking…
OPNFV Verification Program adds VNF testing
LF Networking (LFN) is expanding its OPNFV Verification Program (OVP) to include Virtual Network Function (VNF) compliance testing. The expanded OVP, created in conjunction with the ONAP testing community, now includes publicly-available VNF compliance test tooling based on requirements developed within ONAP, as well as a Verified Labs Program and the induction of the University of New Hampshire-Interoperability Lab (UNH-IOL) as the first OPNFV…
ETSI Multi-access Edge Computing phase 2 specs released
The ETSI Multi-access Edge Computing group (MEC ISG) released the first set of its Phase 2 specifications, including ETSI GS MEC 002 which includes new requirements for Phase 2, ETSI GS MEC 003 dealing with architecture and framework, and ETSI GS MEC 009 giving general principles for service APIs. The updated specs focus on the integration of NFV integration. The specification also describes example use cases and their technical benefits,…
