7 <para>The NFV Access Platform Guide available with this release of Enea
8 Linux, seeks to provide further information that will help all intended
9 users make the most out of the virtualization features.</para>

12 <title>NFV Access Platform Description</title>
13
14 <para>Enea NFV Access is a lightweight virtualization software platform
15 designed for deployment on edge devices at customer premises. Streamlined
16 for high networking performance and minimal footprints for both platform
17 and VNFs, it enables very high compute density.</para>
18
19 <para>ENFV Access also provides a foundation for vCPE agility and
20 innovation, reducing cost and complexity for computing at the network
21 edge. It supports multiple architectures and scales from small white box
22 edge devices up to high-end network servers. Thanks to the streamlined
23 footprint, Enea NFV Access can be deployed on systems as small as single
24 2-core ARM devices. It scales up to clustered 24 core x86 Xeon servers and
25 beyond, allowing multiple VNFs on the same machine, and eliminating the
26 need to use different virtualization software for different hardware
27 platforms, saving costs through single source provisioning.</para>
28
29 <para>Optimized virtual networking performance provides low virtualized
30 networking latency, high virtualized networking throughput (10 Gb wire
31 speed), and low processing overhead. It allows high compute density on
32 white box hardware, maintaining performance when moving functionality from
33 application specific appliances to software on standard hardware. The
34 optimized boot speed minimizes the time from reboot to active services,
35 improving availability.</para>
36
37 <para>Enea NFV Access provides virtualization using both containers and
38 virtual machines. Containers provide lightweight virtualization for a
39 smaller VNF footprint and a very short time interval from start to enabled
40 network services. VMs provide virtualization with secure VNF sandboxing
41 and is the preferred virtualization method for OPNFV compliance. Enea NFV
42 Access allows combinations of containers and VMs for highest possible user
43 adaptability.</para>
44
45 <para>Flexible interfaces for VNF lifecycle management and service
46 function chaining, are important to allow a smooth transition from
47 traditional network appliances to virtualized network functions in
48 existing networks, as they plug into a variety of interfaces. Enea NFV
49 Access supports VNF lifecycle management and service function chaining
50 through OpenStack, NETCONF, REST, CLI and Docker. It integrates a powerful
51 device management framework that enables full FCAPS functionality for
52 powerful management of the platform.</para>
53
54 <para>Building on open source, Enea NFV Access prevents vendor lock-in
55 thanks to its completely open standards and interfaces. Unlike proprietary
56 platforms that either do not allow decoupling of software from hardware,
57 or prevent NVF portability, Enea NFV Access includes optimized components
58 with open interfaces to allow full portability and
59 interoperability.</para>
