It explains how we analyzed the use of SDN based within an NFV environment. We picked the ITU model of Network resources, SDN controller and SDN applications and mapped those elements to the ETSI NFV architecture. Then we studied some design patterns, typical design of a network architecture with SDN and NFV, many different models. We also described SDN hierarchy and federation and collected lessons learnt from ETSI NFV POC using SDN and NFV. Finally we looked into few specific use cases such as Transport Network, or vCPE, but also policy. and last we looked into opensource SDN controller. We ended up with 35 recommendations that we are reviewing now in ETSI NFV to decide upon next steps. Comments welcome !

The Next Step of OpenStack Evolution for NFV DeploymentsDirk Kutscher
NFV is now a well-known concept and in an early deployment stage, leveraging and adapting OpenStack and other Open Source Software systems. In the OPNFV project, a large group of industry peers is building a carrier-grade, integrated, open source reference platform for the NFV community. The telco industry has successfully adopted Open Source Software for carrier-grade deployments. It is now time for taking the next steps and to extend the colloaboration with upstream projects -- by opening up previously proprietary developments, by contributing code and other artifacts in order to create a ecosystem of NFV platforms, applications, and management/orchestration systems.
This talk shares some insights on how Red Hat and NEC are working together to foster collaboration in the NFV ecosystem by actively working with OpenStack and other upstream projects.
NEC has pioneered the adoption of Linux, KVM, Open vSwitch, and OpenStack for their mobile network core product line (virtualized EPC) and has gained significant experience through development work and deployments. NEC's extensions for high efficiency and high availability have led to contributions of new features to OpenStack, such as DPDK vSwitch control and CPU allocation features. For NEC, it is very important to have those features integrated into the mainstream code base for building reliable infrastructure systems.
Red Hat, one of main contributors to OpenStack, leads the development of those functions to meet NFV requirements in OpenStack, making critical and demanding applications run of top of open platforms. The presentation explains how NEC and Red Hat are integrating and optimizing Red Hat Enterprise Linux OpenStack Platform and NFV, along with contributions to open source communities, including OpenStack and Open Platform for NFV (OPNFV).

Challenges in positioning open stack for nf-vi_ are we biting off more than w...OPNFV
Hwee Ming Ng, Red Hat, Sadique Puthen, Red Hat
Many Service providers and communities like OPNFV is seeing OpenStack as the preferred cloud IaaS platform for NFV. However, Openstack was not designed with NFV in mind from day 1 and brings a lot of challenges when adapting to Telco environments. These challenges range from product design and development to solution design and architecture, deployment and support to match Telco expectations.
Red Hat has been working with a number of early adopters to roll out NFV solutions. Even though we have many successes, we have our fair share of challenges. When a solution architect and support engineer stand on the dais, it may be appropriate to recollect these challenges based on our experience from a solution design, architecture and support perspective. These challenges include distributed NFV, High Availability everywhere, Fault Tolerance, Predictive recovery, network performance, interoperability with multiple vendors, accommodating different types of VNFs with different operating systems, troubleshooting, feature availability, etc from a solution design perspective and support perspective.
Throughout this session we will touch base on these challenges, what are the possible solutions, how did we overcome them and open a discussion for challenges which do not have an acceptable solution. We will also discuss details of some of the challenges associated with troubleshooting issues specific to NFV deployments.
Distributed VNF Management - Architecture and Use casesTrinath Somanchi
Telco operators are on journey to discover what virtualization means for the network. Markets have believed that NFV architecture elements: NFVI and VIM, hold the complete responsibility in providing virtualized networks with carrier grade properties.
Telco operators have reached to a conclusion that VNFs must take their fair share of responsibility to realize NFV goals while meeting carrier-grade behavior in the entire NFV architecture. While the trend moves on, Cloud native VNFs are emerging best citizens of the cloud. Thus communication from EMS to VNFM is blurred and eventually may disappear in the future. This requires better understanding of, and agreement over the role of VNFMs and EMS for VNFs.
This presentation describes the evolution of Distributed VNF management, Architectural design considerations and Use-case scenarios. The following proposal is based on a comprehensive study on evolving cloud native VNF management.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Lesson #3. VNF on-boarding is far from being seamless, killing the benefits in
terms of OPEX and Time to Market

Lesson #4. Most approaches for lifecycle, focused on use cases of anecdotic
value for network operation…
LITTLE GAIN FROM AUTO-SCALING
- Peak periods correlated at PoP level!
AUTONOMOUS ACTIONS AT VNF LEVEL MAY LEAD TO INSTABILITY
- VNFs are often middlepoints of an E2E service
- Uncertain protection against chain reactions
APPROACHES TO LIFECYCLE OFTEN REQUIRE “EXCEPTIONS” FOR EVOLUTIONARY
DEPLOYMENTS
- Resource Orchestration and Service Orchestration often convoluted in NFV
- “Legacy” OSS needs clear boundaries between them!
… WHILE ADDING HUGE COMPLEXITY TO COMMON USE CASES
- Proposed abstractions, often unfriendly for network engineering

Lesson #5. There are issues to orchestrate evolutionary multi-vendor
scenarios, even for simple ‘network creation’
•VNFs seen as PNFs from OSS point of view
•Predictable performance
•Scenarios can be saved and re-deployed
•Low entry barriers
Vendor- and VNF-agnostic
No formal integration
WHAT IS NEEDED TO START…
•No utilities for network design
•Low performance
No EPA awareness
•NFVO-OSS coordination is
often needed
•Not ready for creating
scenario snapshots
•“Sticky” MAC addresses
prevent re-deployment
•VNFs still need formal
integration with MANO!
High entry barriers in practice

Conclusions
CLASSIC CLOUD CANNOT PROVIDE CARRIER-GRADE PERFORMANCE
- Does not have proper view of HW resources
- Introduces unintended contention in packet processing
PROPER VNF DESCRIPTORS ARE KEY FOR
