SDN and NFV both aim to virtualize and commoditize network hardware to reduce costs and increase flexibility. SDN separates the control plane from the data plane to allow centralized control of network behavior via software. NFV virtualizes network functions like firewalls and load balancers that were traditionally hardware appliances. Both seek to standardize networking functions through open source projects and standards bodies like ONF for SDN and ETSI for NFV. Major implementations include OpenStack for virtual infrastructure, OpenDaylight as an SDN controller, and OpenFlow as the SDN protocol. While complementary, SDN and NFV face challenges around vendor support and complexity that could slow wide adoption.
If you’re in Tech and haven’t heard about Docker, you’ve been living under a rock. The ultimate Silicon Valley darling went from a two-person startup into becoming the de facto standard of modern application design virtually overnight. Two years ago very few people knew about Docker. Today, if your software is not supporting Docker, you’re not part of the cool kids club. In my opinion Docker is a marketing driven company because early on it understood the needs of their customers, i.e. the developers, and created three fantastic value propositions. First, Docker solved an important problem for developers: it overcame the limitations of the existing Linux container technologies and made the promise “build an app once, run it anywhere” possible. Second, Docker adopted “give before you take” attitude, open-sourced their code and contributed to the DevOps community early on. Lastly, Docker focused on making the developer’s life as easy as possible by building a bunch of tools to automate mundane tasks.

Dr. Christos Kolias – Senior Research Scientist
Keynote Title: “NFV: Empowering the Network”
Keynote Abstract: Network Functions Virtualization (NFV) envisions and promises to change the service provider landscape and has emerged as one of one of today’s significant trends. Although less than two years old, NFV has garnered the industry’s full attention and support. Moving swiftly, a number of key accomplishments have already taken place, and a lot more work is currently under way within ETSI NFV while we are embarking on its future phase. Various proofs-of-concepts (ranging from vEPC to vCPE, vIMS and vCDN) are being developed while issues such as open source and SDN are becoming key ingredients as the can play a pivotal role.
Dr. Christos Kolias' Bio: Christos Kolias is a senior research scientist at Orange Silicon Valley (a subsidiary of Orange). Christos is a co-founder of the ETSI NFV group and had led the formation of ONF’s Wireless & Mobile working group. He has lectured on NFV and SDN at several events. Christos has more than 15 years of experience in networking, he is the originator of Virtual Output Queueing (VOQ) used in packet switching. He holds a Ph.D. in Computer Science from UCLA.

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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications.

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.

SDN NFV
“Think of it as a general language or an instruction
set that lets me write a control program for the
network rather than having to rewrite all of code on
each individual router”
Scott Shenker, Professor at UC Berkley
“NFV will have a tremendous impact. It means we'll
rebuild all telecom networks from how they are built
today. When it's done, it will give a major benefit.”
Johan Wibergh, Networks Head at Ericsson
5. Applicability
SDN NFV
• Optimize network infrastructure such as
Ethernet switches, routers and wireless
access points
• OSI Layer 2-3
• Optimize deployment of network functions
such as: load balancer, firewall, WAN
optimization controller, deep packet
inspection etc.
• OSI Layer 4-7
6. Analogies

Distributed intelligence using complex
protocols and purpose-built network
devices, manipulated via low level
configuration files and CLI

7. Benefits
SDN NFV
• Simplify configuration as the entire network,
often comprised of thousands of physical
routers, switches etc. from different vendors, can
be programmed with a single API
• Simplify operations as the entire network is now
reduced to a single switch from an application or
a policy control function perspective
• Reduce cost of the network as expensive,
feature-rich switches and routers are no longer
needed
• Accelerate time-to-market of new services as
application-level changes will no longer require
hardware-level modifications
• Simplify the process of procurement, design,
integration and maintenance of the infrastructure
as it is now heavily standardized
• Increase agility/scalability by dynamically
allocating hardware level capacity to the network
functions needed at a given time

9. SDN transformation in the Data Center
DataCenter
Core
Routers
In a classical router or switch architecture, the packet
forwarding (data path) and the high level routing
decisions (control path) occur on the same device. The
routing protocol engine programs forwarding decisions
on the local device, i.e. router, using OSPF or BGP.
In SDN, there is a separation of control and forwarding
planes. The data path portion still resides on the switch,
while high-level routing decisions are moved to a
separate controller, typically a standard server. The
controller uses the OpenFlow protocol to program the
forwarding decisions into the switches.

14. Virtualization Framework for Telco
Motivation Contributors
It started in October 2012 when 13 tier-one
network operators from around the globe
issued a call for action to the industry in the
form of their first white paper on NFV. The
operators firmly believed that NFV would
increase network performance and
capabilities more cost-effectively than before,
and they stated their commitment to this
approach.
ETSI has signed a cooperation agreement
with the Open Networking Foundation in an
effort to align the standards work of SDN and
NFV, and bring the results to a wider
community.
215 member organizations, 34 of which are
network operators:
A lot of traditional networking and IT vendors:

15. Operating System for Cloud
Motivation Contributors
OpenStack is a global collaboration of
developers and cloud computing
technologists producing the ubiquitous open
source cloud computing platform for public
and private clouds.
The project aims to deliver solutions for all
types of clouds by being simple to implement,
massively scalable, and feature rich. The
technology consists of a series of interrelated
projects delivering various components for a
cloud infrastructure solution.

16. SDN Controller
Motivation Contributors
OpenDaylight is an open source project with
a modular, pluggable, and flexible controller
platform at its core. This controller is
implemented strictly in software and is
contained within its own Java Virtual Machine
(JVM). As such, it can be deployed on any
hardware and operating system platform that
supports Java.
http://www.opendaylight.org/
17. SDN Protocol
Motivation Contributors
• OpenFlow is the protocol that aims to
separate the intelligence required to route
a packet from the act of moving a packet–
can commoditize the switches and routers.
• Just like x86 processors turned the server
market into a battle over new features on
a consistent platform, networking gear will
soon be about a consistent platform where
features matter and vendors can’t lock in
their clients.
• OpenFlow enables remote programming
of the forwarding plane. The OpenFlow
Standard is the first SDN standard and a
vital element of an open software-defined
network architecture.
