NFV aims to reduce network operators' costs and improve service delivery speeds by using virtualization technology to consolidate network functions onto industry-standard servers and switches located in data centers. This allows functions like routing, firewalls, and load balancing to be delivered as software rather than via proprietary hardware appliances. NFV promises benefits like reduced capital and operational expenditures, increased flexibility and agility to deploy new services, and easier scaling of network functions. The ETSI NFV working group is working to define requirements and approaches for NFV implementation through industry collaboration.

Software-Defined Networking (SDN): Unleashing the Power of the NetworkRobert Keahey
It goes without saying that cloud computing has dramatically reshaped the information technology services landscape. Virtualization is unleashing the power of commodity-based technology and open source communities are building new applications and services at an astonishing rate, but networking has lagged behind compute and storage in virtualization and automation. We’ve become accustomed to specialized networking silicon, complex operating systems and highly distributed control planes. For the most part, we’ve accepted the model along with its high costs.
All that is changing! New protocols such as OpenFlow are freeing the network control plane from proprietary operating systems and hardware platforms. We are entering a new era where customers control the features – and release schedules – of new, open networking applications that address the needs of the mega-scale world.
A lot of work is required to realize the potential of Software-Defined Networking (SDN), where we can enjoy the benefits derived from “software automating software.” This talk will examine some of the history that led us to the point where current networking architectures are no longer viable for cloud computing at mega-scale. We’ll take a look at the basics of SDN and some of its key elements – OpenFlow, network virtualization, and orchestration – along with some of the initiatives and companies that are setting the stage for the next generation of networking.
Software Defined Networks (SDN) is an evolutionary paradigm that will not only change how the vendors will built their products and technologies, but also change how the organizations are going to consume these capabilities. That said, adoption of these SDN capabilities is very low. Some of them is shaped by the myths and expectations around what SDN can versus cannot do. It is therefore important to understand these adoption challenges and correspondingly use some of the consultative services frameworks to overcome these challenges.

Research Challenges and Opportunities in the Era of the Internet of Everythin...Stenio Fernandes
Currently there is increasing interest in scientific research on network traffic management for advanced scenarios (e.g. Internet of Everything (IoE), Everything as a Service (XaaS), Smart Cities, and the like) and their respective demands for novel network services. Such networked applications bring massive amounts of traffic data to be processed in real-time, thus driving researchers to develop affordable yet efficient network management systems. In fact, new paradigms, services, and architectures, such as Network Virtualization (NV), Software-Defined Networking (SDN), Distributed Cloud Computing, Network Functions Virtualization (NFV), Service Function Chaining (SFC), etc, will require robust and dynamic capabilities to support a myriad of possibilities for applications from the IoE and XaaS concepts. For example, there is a need for an in-depth understanding of the composition and the dynamics of Internet traffic to perform accurate capacity planning, deploy efficient management policies and pricing strategies, assess protocol performance, and detect abnormalities in such scenarios. Research on measurement, modeling, and analysis of network traffic and infrastructure always face new challenges as new applications are continuously deployed.
In this talk, I will discuss the rise of IoE and XaaS as well as the demand for advanced networking services, paradigms, and architectures (e.g., SDN, NFV). I will give an overview of some challenges, opportunities, and directions in these research topics.
IT teams face unprecedented challenges to support dynamic application requirements on top of a rigid legacy infrastructure. A vendor-agnostic orchestration helps deliver rapid network
services for multi-vendor infrastructure. Anuta NCX platform with it’s layered, YANG model-driven and abstraction approach helps in delivering vendor neutral, extensible and maintainable
services for multiple domains such as Branch/CPE, Data Center, Cloud, and Carrier Core networks. The NCX platform enables customers and partners to develop their own Service and Device models for complete customization within few days. Many large enterprises and service providers have deployed NCX to orchestrate their brownfield and greenfield networks.

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.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Why Network Functions Virtualization??
Network Functions Virtualization (NFV) explicitly targets the two biggest problems facing network
operators: bringing costs in line with revenue growth expectations and improving service velocity. NFV's
premise is that industry standard IT virtualization technology (servers, switches, and storage) located in
data centers, network nodes, or end-users' premises can be used to reduce the cost and increase the
speed of service delivery for fixed and mobile networking functions. We believe Network Functions
Virtualization is applicable to any data plane packet processing and control plane function in fixed
and mobile network infrastructures.
What Makes NFV Different
While PC-based network devices have been available since the '80s, they were generally used by small
companies and networking enthusiasts who didn't or couldn't afford to buy a commercial-based solution.
In the last few years many drivers have brought PC-based networking devices back into the limelight,
including: Ethernet as the last mile, better network interface cards, and Intel's focus on networking
processing in its last few generation of chips.
Today many vendors are producing PC-based network devices. Advancements in packet handling within
Intel's processors, allowing processor cores to be re-programmed into network processors, allow PC-
based network devices to push 10's or even 100's of Gbp/s.
Values of NFV
Some of the values to the NFV concept are speed, agility, and cost reduction. By centralizing designs
around commodity server hardware, network operators can:
• Do a single PoP/Site design based on commodity compute hardware;
• Avoiding designs involving one-off installs of appliances that have different power, cooling and
space needs simplifies planning.
• Utilize resources more effectively;
• Virtualization allows providers to allocate only the necessary resources needed by each
feature/function.
• Deploy network functions without having to send engineers to each site;
o “Truck Rolls” are costly both from a time and money standpoint.
• Achieve Reductions in OpEX and CapEX; and,
• Achieve Reduction of system complexity i.e Deliver Agility and Flexibility: quickly scale up or
down services to address changing demands; support innovation by enabling services to be
delivered via software on any industry-standard server hardware
• Accelerate Time-to-Market: reducing the time to deploy new networking services to support
changing business requirements, seize new market opportunities and improve return on
investment of new services. Also lowers the risks associated with rolling out new services,
allowing providers to easily trial and evolve services to determine what best meets the needs of
customers.
• Error resilience : Ensuring the appropriate level of resilience to hardware and software failures.
• Scale: Network Functions Virtualization will only scale if all of the functions can be automated.
2. Overview of the ETSI NFV ISG
The ETSI Board approved foundation of the NFV ISG in time for publication of our first white paper
last October. ETSI is a global organisation and has proved to be an excellent environment in which to
Network Functions virtualization progress our work and we extend our thanks to the Director General and
the ETSI Board for their accommodation and support. Although ETSI is a Standards Development
Organisation (SDO), the objective of the NFV ISG is not to produce standards. The key objectives are to
achieve industry consensus on business and technical requirements for NFV, and to agree common
approaches to meeting these requirements. The outputs are openly published and shared with relevant
standards bodies, industry fora and consortia to encourage a wider collaborative effort. The NFV ISG will
collaborate with other SDOs if any standardization is necessary to meet the requirements. The NFV ISG
also provides an environment for the industry to collaborate on Proof of Concept (PoC) platforms to
demonstrate solutions which address the technical challenges for NFV implementation
and to encourage growth of an open ecosystem
NFV: Vision
NFV architecture Model
• Network operators have proven NFV feasibility via proof of concept test platforms
• Network operators and vendors have identified numerous “fields of application” spanning all
domains (fixed and mobile network infrastructures)
• Significant CAPEX/OPEX benefits, leveraging also the economies of scale
• Emerging virtual network appliance market
• Novel ways to architect and operate networks, spawning a new wave of industry wide innovation
• Network Functions Virtualization can dramatically change the telecom landscape and industry
over the next 2-5 years
3. NFV Relationship with Software Defined Networks (SDN)
Whereas SDN was created by researchers and data center architects, NFV was created by a consortium
of service providers. The original NFV white paper1
describes the problems that they are facing, along
with their proposed solution, Link1 to white paper has complete information about this.
SDN and NFV – Working Together?
Let’s look at an example of how SDN and NFV could work together. Figure shows how a managed router
service is implemented today, using a router at the customer site.
Network Functions virtualizations goals can be achieved using non-SDN mechanisms, relying on the
techniques currently in use in many datacenters. But approaches relying on the separation of the control
and data forwarding planes as proposed by SDN can enhance performance, simplify compatibility with
existing deployments, and facilitate operation and maintenance procedures. Network Functions
Virtualization is able to support SDN by providing the infrastructure upon which the SDN software can be
run. Furthermore, Network Functions Virtualization aligns closely with the SDN objectives to use
commodity servers and switches.
1 1
http://portal.etsi.org/portal/server.pt/community/NFV
4. Managed Router Service Today
NFV would be applied to this situation by virtualizing the router function, as shown in Figure. All that is left
at the customer site is a Network Interface Device (NID) for providing a point of demarcation as well as for
measuring performance.
5. Managed Router Service Using NFV
Finally, SDN is introduced to separate the control and data, as shown in Figure. Now, the data packets
are forwarded by an optimized data plane, while the routing (control plane) function is running in a virtual
machine running in a rack mount server.
Managed Router Service Using NFV and SDN
The combination of SDN and NFV shown in Figure provides an optimum solution:
• An expensive and dedicated appliance is replaced by generic hardware and advanced software.
• The software control plane is moved from an expensive location (in dedicated platform) to an
optimized location (server in a data center or POP).
• The control of the data plane has been abstracted and standardized, allowing for network and
application evolution without the need for upgrades of network devices.
How NFV will push SDN beyond the data center
NFV's use of virtual network overlays could also drive an expansion of this SDN model beyond the data
center where it's focused most often today. If NFV allows services to be composed of virtual functions
hosted in different data centers, that would require virtual networks to stretch across data centers and
become end-to-end. An end-to-end virtual network would be far more interesting to enterprises than one
limited to the data center. Building application-specific networks that extend to the branch locations might
usher in a new model for application access control, application performance management and even
application security.
Will NFV unify differing SDN models?
6. With the use of network overlays, NFV could also unify the two models of SDN infrastructure -- centralized
and distributed. If connectivity control and application component or user isolation are managed by the
network overlay, then the physical-network mission of SDN can be more constrained to traffic management.
If SDN manages aggregated routes more than individual application flows, it could be more scalable.
Remember that the most commonly referenced SDN applications today -- data center LANs and Google's
SDN IP core network -- are more route-driven than flow-driven. Unification of the SDN model might also
make it easier to sort out SDN implementations. The lower physical network SDN in this two-layer model
might easily be created using revisions to existing protocols, which has already been proposed. While it
doesn't offer the kind of application connectivity control some would like, that requirement would be met by
the higher software virtual network layer or overlay.
Why NFV is the future?
• Recent tests by network operators and vendors have demonstrated that network functions can
operate at the level of several millions of packets per sec, per CPU core
• Demonstrates that standard high volume servers have sufficient processing performance to cost-
effectively virtualized network appliances
o The hypervisor need not be a bottleneck
o The OS need not be a bottleneck
• Total Cost of Ownership advantages are a huge driver – could be scenario specific but expect
significant benefits, e.g., energy savings
• Advances in virtualization & server technologies have propelled the importance and use of
software in many applications and fields
• A concerted industry effort is underway to accelerate this vision by encouraging common
approaches which address the challenges for NFV
