The present document specifies the interfaces supported over the Vi-Vnfm reference point of the NFV-MANO architectural framework as well as the information elements exchanged over those interfaces.
The present document specifies the interfaces supported over the Or-Vi reference point of the NFV-MANO architectural framework ETSI GS NFV 002 as well as the information elements exchanged over those interfaces.
The present document specifies the interfaces supported over the Or-Vi reference point of the NFV-MANO architectural framework ETSI GS NFV 002 as well as the information elements exchanged over those interfaces.
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).
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.
The present document specifies requirements for a set of abstract interfaces enabling a VNF to leverage acceleration services from the infrastructure, regardless of their implementation. The present document also provides an acceleration architectural model to support its deployment model.
The goals of the present document are:
VNF providers have to mitigate two goals:
The present document is an informative architectural study that identifies different viable architectural and functional options for the partitioning/distribution/consolidation of functionality amongst NFV-MANO functional blocks defined in NFV architectural document ETSI GS NFV 002 and further refined in NFV-MANO architectural framework ETSI GS NFV-MAN 001, as well as the potential impact in each case on reference points, on interfaces associated with the reference points, and on information elements exchanged over those interfaces.
Network Functions Virtualisation (NFV) adds new capabilities to communications networks and requires a new set of management and orchestration functions to be added to the current model of operations, administration, maintenance and provisioning. The NFV Management and Orchestration (NFV-MANO) architectural framework has the role to manage the infrastructure and orchestrate the resources needed by the Network Services (NSs) and Virtualised Network Functions (VNFs).
In order to guide the development of the specification of the interfaces exposed between the NFV-MANO Functional Blocks (FBs), it is important to have a clear and consolidated set of functional requirements to be addressed by the NFV-MANO. The present document is providing functional requirements on NFV MANO e.g. VNF lifecycle management (LCM), NS LCM, virtualised resource management, etc.
The functional requirements specified in the present document are mainly derived from functional requirements identified in ETSI GS NFV 002, ETSI GS NFV 003, ETSI GS NFV 004, ETSI GS NFV-MAN 001, ETSI GS NFV-SWA 001, ETSI GS NFV-REL 001 and ETSI GS NFV-INF 001 or derived from concepts defined in these documents.
The present document specifies the performance measurements that are exposed on various NFV MANO reference points (e.g. Or-Vnfm, Ve-Vnfm-em, Vi-Vnfm, Or-Vi and Os-Ma-nfvo). ETSI GS NFV-TST 008 specifies the Network Function Virtualisation Infrastructure (NFVI) performance metrics that will be reported to Virtualised Infrastructure Manager (VIM). VIM processes the performance metrics received from NFVI to generate performance measurements to be sent to NFV Orchestrator (NFVO) and VNF Manager (VNFM). VNFM and NFVO conduct further processing to generate performance measurements.
The present document defines the requirements to interface the Security Control to NFV-MANO as described in ETSI GS NFV-SEC 013 and the LI Controller in ETSI GR NFV-SEC 011. The present document identifies the extensions to the NFV-MANO architecture related to security management and monitoring. Multiple trust domains are considered.
The present document specifies the interfaces used for acceleration resource management on the Nf-Vi reference point of the NFV MANO framework, as well as the information elements exchanged over those interfaces.
The present document specifies the network acceleration related interfaces supported over the Vn-Nf reference point of the NFV architectural framework between a VNF and a dedicated switch controlled by that VNF. The present document also defines information elements exchanged over those interfaces.
The present document is built on the use of the Dynamic Optimization of Packet Flow Routing (DOPFR) mechanism (see use case described in ETSI GS NFV-IFA 001). Based on DOPFR, the present document aims to design a common interface allowing a Network Intensive VNF (NI-VNF) to accelerate its data plane processing on a dedicated switch.
