As SDN & NFV services become commercially available, the industry needs to approach once again the reach issue. There is not a single service provider with complete reach; that is why we build NNIs and need a wider SDN/NFV Ecosystem.
Slides introducing NFV and what is done on the subject in OpenStack and explaining the benefits of 6WIND Gate in an NFVi setup with OpenStack. Presentation done with Vincent Jardin, CTO at 6WIND.

If you missed my presentation at the SDN World Congress this week, here it is !
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 !
And if you want to see real life implementations, go and see HP NFV POC #34 and #38 in the POC Zone on site in Dusselfdorf this week Oct 8-16 2015 !

Enterprise Datacenter Virtualization und Cloud Computing stellen neue Anforderungen an das Netzwerk. Traditionsgemäss wurden virtuelle Workloads über als Bridge fungierende virtuelle Switches mit VLANs auf dem physischen Netzwerk verbunden. Mit dem Wachstum der Anfordungen an Skalierung und Automatisierung stossen diese Modelle an Grenzen.
Thomas Graf bot an diesem OpenTuesday einen Einblick in Protokolle und Technologien wie OpenFlow, VXLAN, OpenStack Neutron und Open vSwitch, die eingesetzt werden, um neue automatisierte Netzwerkkonzepte der nächsten Generation, wie Software Defined Networking oder Network Function Virtualization, umzusetzen.
Le SDN et NFV sont très à la mode en ce moment car en passant des appliance physiques aux équipement réseau massivement logiciel, celà devrait offrir une grande flexibilité et agilité aux entreprises (et telco en particulier). Néanmoins chainer des services réseau est un exercice encore très complexe et ce document vous explique ce qu'il est déjà possible de faire sur OpenStack en couplant par exemple : un load balancer (BigIP), un Firewall (BigIP), un réseau virtuel WAN (RiverBed) ou encore un routeur virtuel (Brocade).
Edge Computing: A Unified Infrastructure for all the Different PiecesCloudify Community
Edge Computing along with 5G promises to revolutionize customer experience with immersive applications that we can only imagine at this point. The edge will include PNFs, VNFs, and mobile-edge applications; requiring containers, virtual machines and bare-metal compute. But while edge computing promises numerous new revenue streams, managing and orchestrating these edge infrastructure environments is not going to be a seamless, instant process. In this webinar, experts in NFV orchestration discuss the concerns you must address in the transition to the edge, and show how you can use available open source tools to create a single management environment for PNFs, VNFs, and mobile-edge applications.
Learn more about how today's service provider's networks are built to deliver yesterday's services and how the Next generation service require a new approach with our Evolved Programmable Network's offerings will enable business transformation for new service deliveries.

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.

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. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

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.
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.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

• SDN is (still) in its early days. Most of the work by ONF/IETF/NFV still to be
done (long journey). Most SDN products not GA - dust will settle eventually
• Carrier class OpenFlow switches not generally available in the market (2012).
However, DC SDN overlay solutions are a reality (Pilot completed, vendor
selected, deployment on-going in Colt)
• SDN/Network Programmability fits extremely well with Colt’s strategy to
deliver integrated IT & Network services to our customers
– SDN key for automation and orchestration/policy (faster delivery/change, more agility,
better utilisation, standard services)
• NFV and service chaining will change the way we deliver L3-L7 services even
