4 Release overview
4.1 Introduction
ETSI ISG NFV Release 3 (hereinafter referred also as Release 3 or the present Release) builds on top and leverages the
results of ETS ISG NFV documents published by the end of 2014. The NFV Release 2 did not include any architectural
changes and the list of capabilities part of the Release were thus aligned with the ETSI NFV Architectural Framework,
see ETSI GS NFV 006 [i.3]. The Release 3 introduces new features on top of the Release 2 specified capabilities.

The feature provides NFV related management and orchestration operations to flexibly allocate VNFs to available
NFVI and acceleration components by exposing acceleration capabilities instead of specific acceleration resource
characteristics.
Four interfaces support the exchanges between the NFVI and VIM regarding acceleration resource management:
- acceleration Resource Discovery;
- acceleration Resource Lifecycle Management;
- acceleration Resource Fault Management; and

5.2.2 Network acceleration for VNF (FASTSWITCH)
5.2.2.1 Description
The feature encompasses the interaction (e.g. interfaces) between the virtualization layer and switching accelerator
drivers to enable network acceleration transparent to the VNF and to be independent of any accelerator vendor and type.
The feature specification is built on the use of the Dynamic Optimization of Packet Flow Routing (DOPFR) mechanism
which offers the capability to accelerate the data plane processing of a VNF on a dedicated switch
