1.  NFV and SDN are highly complementary, they are mutually beneficial but not dependent on each other (NFV can be
deployed without SDN andvice-versa)
2.  SDN can enhance NFV performance, simplify compatibility, facilitate operations
3.  NFV aligns closely with SDN objectives to use software, virtualization and IT orchestration and management techniques

5G network will be based on slices on top of the same infrastructure
-  NFV and SDN as the main enablerfor:
-  the business agility – with its capabilities for on-demand, fast deployments
-  the network adaptability – requires redesign of network functions (to cloud native)
-  the flexibility – support for functions variance, flexible function allocation, etc.
-  the composition – putting multiple services together in a slice – end-to-endmanagement
-  the slicing – enabling separation at networklevel
-  the customization – enabling different network services of the same type
-  the programmability – software-only network functions and theirinteraction
with the physicalsystems
è Orchestration is the cornerstone for all of these features
NFV and SDN are the support technologies for 5G

Constraints

Role of SDN/NFV in the Networking Stack
SDN/NFV provide a novel virtual service enablement layer
-  SDN/NFV platform acts as an end-to-end middlewarebetween:
-  A distributed heterogeneous infrastructure including dedicated components (e.g. radio), heterogeneous datacenters
(compute & storage) and inter-connecting networks (fronthaul, backhaul, third party backbone, etc.)
-  Generic network functions implemented in software and running in virtual machines
-  Virtualised IMS, EPC, radio and SGi components, home and enterprise networks, Application Servers, etc.

In the ETSI NFV architecture, the Orchestrator is the main decision point in the interaction between
services and infrastructure.
-  The Orchestrator is the only component which has a complete view of the infrastructure resources
-  The Orchestrator allocates the resources for the services based on theirrequirements
-  The Orchestrator maintains the resources of the network services at the expected parameters during the life-cycle
management
-  Functionality roles of theorchestrator:
-  Life-cycle management of the network services
-  Ensuring the network KPIs arefulfilled
-  Ensuring dynamic managementfunctionality:
-  Keeping system coherence whilescaling
-  end-to-end fault management,
-  end-to-endreliability
Why do we need an orchestrator?
11
© Fraunhofer FOKUS

A comprehensive MANO orchestrator is (still) missing…
Two approaches in regard to orchestration were taken:
-  Orchestrating from the infrastructureperspective
-  Extending the VIM functionality towards proving service orchestration. Missing:
-  Adaptation to complex network services requirements:
-  e.g. fault management, scaling, network function placement, virtual network configuration,
information flow paths, security, reliability
-  Orchestrating from the network serviceperspective
-  Extending the Network Management System to handle orchestration.
Missing:
-  Capitalize through native developed components on the cloud
opportunities: scaling, dynamic resource allocation
-  Fix the remaining problems: define the appropriate network
service KPIs, end-to-end fault management, providing end-to-end
reliability insurance, etc.
è With more than 10 years of experience in network services and network services implementation as software and in
cloud management, Fraunhofer FOKUS is in the unique position to understand and practically implement the
connection between the twoworlds.

What is OpenBaton?
OpenBaton is an Open Source implementation of the ETSI MANO
specification
-  OpenBaton aims to foster, within the NFV framework, the integration betweenthe:
-  Virtual Network Function providers
-  Cloud Infrastructure providers
-  Functionality:
-  Installation, deployment and configuration of network services
-  Runs on top of multi-site OpenStack
-  Provides independent infrastructure slices
-  Support for generic or specific VNF management
-  Runtime operations: fault management, autoscaling, etc.
-  A large amount of virtualization use cases
e.g. core networks, M2M and Multimedia communication
-  Designed for answering R&Drequirements
-  Easy to configure and to deploy
-  Providing a centralized view of the testbed
-  Available on github:https://github.com/openbaton 27
© Fraunhofer FOKUS

-  No vendor lock-in: OpenBaton does not contain any vendor specific features. It follows
open specifications and it is open to the community
-  Built from scratch following the ETSI MANOspecification.
-  The NFVO uses the ETSI NFV data model internally for the definition of the Network Service and
Virtual Network Descriptors.
-  Allows interoperability
-  Being interoperable is one of the challenges brought by the fragmented ecosystem in the
management and orchestration area. It requires a lot of work to make two different vendors
solution working together à need of a single vendor-independent platform
-  Gives a fast access to Fraunhofer know-how
-  Large experience in network functions implementations (assoftware)
-  Large experience in cloud networkmanagement

What OpenBaton stands for

The reference implementation of the ETSI NFV MANO specification
−  Open Baton is based on the ETSI NFV MANO v1.1.1 (2014-12) (*) specification. It
provides
−  A NFV Orchestrator managing the lifecycle of Network Service Descriptors
(NSD) and interfacing with one or more VNF Manager(s)(VNFM)
−  A generic VNFM, which can be easily extended for supporting different type of
VNFs
−  An Autoscaling Engine which can be used for automatic runtime management
of theVNFs
−  A Fault Management System for automatic management of faults
−  A set of libraries which could be used for building your own VNFMs (vnfm-sdk)
−  A dashboard for easily managing all the VNFs
−  It integrates with OpenStack as main VIM implementation
Open Baton the game changer into the NFV environment

Open Baton provides a set of libraries for integrating new network services
Do you have a VNF, and would like to
orchestrate it using Open Baton?
-  All you need to do is to implement your
installation scripts and a VNFM. The
NFVO supports two different mechanisms
for interacting with your VNFM.
-  We provide a Java SDK (soon to be
extended with a python version) which
can help you on building your VNFM
Integrating your own network service

Soon to come a VNF catalogues where you can choose existing open source VNFs for
interoperability testing
In case you are developing a specific
VNF and would like to integrate in a
Network Service
-  Make use of the open catalogue for
downloading and using existing
VNFs
-  Create your own instance
independent of the catalogue
-  Adapt your own VNF to the existing
VNFs
-  Contribute to the community with
your own VNFs.
