Ildikó Váncsa, Chris Price, and Carsten Rossenhövel's presentation at the 2017 Open Networking Summit.
Communications service providers (CSPs) have a wide range of options when building virtualized services from the ground up including multiple choices for each functional block in the ETSI NFV reference architecture. CSPs prefer heterogeneous systems with building blocks from different vendors including open source software; for such deployments interoperability becomes a crucial requirement.
OpenStack, as the NFVI and VIM, serves as a widely used cloud platform for telecom and NFV use cases. As a common base, OpenStack offers the means for vendors and other open source projects to ease the interoperability challenge by providing a set of open API’s while focusing on upgradeability and backward compatibility.
However, when it comes to productization, interoperability testing often falls short and is sometimes left to the carrier as shown by the testing programs actively run by no fewer than 10 organizations today.
Join Carsten Rossenhövel from the European Advanced Networking Test Center (EANTC) and the rapporteur (editor) of ETSI’s NFV interoperability standards, Ildikó Váncsa from the OpenStack Foundation, and Chris Price, Ericsson and OpenStack board director to learn more about
The ETSI NFV Release 2 interoperability testing activities - standardization and recently completed ETSI PlugTest. Over 40 commercial and open source implementations were tested for interoperability, including 20 virtual network functions, 10 management and orchestration solutions and 10 NFV platforms.
The New IP Agency (NIA) interoperability testing campaigns of commercial NFV implementations executed by EANTC, focusing on results, lessons learned and recommendations.
How vendors and open source projects are stepping up to the challenge, realizing they must work together.
How to stay up-to-date with OpenStack releases and the community.
How to get involved to ensure you are aware of the latest developments and contribute what you need to OpenStack.
What will I learn from attending this session?
CSPs, open source projects and vendors alike will learn more about the recent ETSI PlugTest and NIA-commissioned interoperability testing, their results and how to architect full NFV solutions that will work together. Interoperability API tests and associated marks from OpenStack will be covered, as well as features to help stay current on OpenStack releases. Attendees will also hear from Ericsson about a vendor’s point of view, and how other projects such a OPNFV are evolving and expanding in scope to address this challenge.
Christophe Alter of Orange Telecom presented to attendees of MPLS+SDN+NFV World in Paris in March 2017. He discussed the OIF's new certification program.
Traditional carriers' transport networks consist of vertically-integrated devices with vendor-proprietary interfaces, that causes "vendor lock in" environment and interferes with adopting software based control and configuration for carriers' transport networks. NTT Communications are trying to adopt disaggregation approach for them to transform our operations by integrating commoditized multi-vendor components and SDN technology.
In this presentation, we will talk about our expectations for disaggregated transport networks and its controller architecture with multiple SDN controllers including open source software. Furthermore, we will show our internal evaluation result of disaggregated transport network feasibility and discuss future development plans.
Providing carriers with essential tools in the

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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
