The Interoperability Challenge in Telecom and NFS Environments
The Interoperability Challenge in Telecom and NFS EnvironmentsOpen Networking Summit 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.

Get Loose! Microservices and Loosely Coupled Architectures 
Get Loose! Microservices and Loosely Coupled Architectures DevOps.com The recently published results from the 2017 State of DevOps Survey shows that loosely coupled architectures and teams are the strongest predictor of continuous delivery. Microservices and Containers are a great choice for creating these loosely coupled systems. But, many teams find it hard to decompose monolithic applications into Microservices, and they find it harder still to coordinate deployments and releases into the emergent “hyper-hybrid” operating environments.

Turning up the HEAT with IBM MobileFirst for iOS Apps
Turning up the HEAT with IBM MobileFirst for iOS AppsMichael Elder The landmark partnership between Apple and IBM announced last year set the internet abuzz. The partnership aims to spark true mobile-led business change across the
enterprise. In this talk, we’ll show you how IBM is using OpenStack, Heat, and DevOps to
deploy a truly monumental undertaking.
To fulfill this goal, we needed to redefine how we deliver our software. Leveraging IBM’s unique expertise in OpenStack and DevOps, we turned the “art of the possible” into our new “reality”. In this talk, we’ll tell the story of how we used fullstack application patterns based on OpenStack Heat to provision environments with speed and reliability. You will hear directly from the joint development team how these patterns enabled us to collaborate unimpeded by the traditional road blocks of IT development. As it turns out, our goal to “spark true business change” has
extended beyond our customers to include IBM itself.
You will not only hear about the technical solution but see it in action with a demo in the session.

Arachne: How does Uber check the health of its Network Infrastructure every 1...Open Networking Summit One of the major challenges and requirements in achieving a very high (>99.99%) reliability of operation of any major network infrastructure (i.e. data center, enterprise, campus, etc.) is the ability to design and deploy an always-on active system that performs end-to-end functional testing of all the network-connected infrastructure components and, as a result, monitors the infrastructure and its dependent external services with high accuracy and granularity (down to the packet level) in the most efficient way; consuming the least amount of computational or network resources.
When it comes to packet loss detection, metrics reported by the original manufacturers cannot be relied upon; their tools may either be buggy or, in most cases, do not provide APIs for extracting measurements. Therefore, we needed to create our own tool; this is the gap Arachne is filling.
In this talk, we present Arachne. Arachne is a packet loss detection system and an underperforming path detection system. It provides fast and easy active end-to-end functional testing of all the components in Data Center (DC) and Cloud infrastructures. Arachne is able to detect intra-DC, inter-DC, DC-to-Cloud, and DC-to-External-Services issues by generating minimal traffic.

Troubleshooting for Intent-based Networking
Troubleshooting for Intent-based NetworkingOpen Networking Summit Joon-Myung Kang and Mario A. Sánchez's presentation at the 2017 Open Networking Summit.
Intent-based networking has gained a lot of interest in recent years with several different open source communities (including ONF, OpenDaylight and ONOS). However, network diagnosis and troubleshooting remain two essential aspects of network management that still require massive manual effort and extensive expert knowledge. So far, no approach has focused on troubleshooting the network at the intent level. We argue that providing reasoning capabilities about why an observed network state happens according to specified input policies can help simplify this complexity. In this talk, we present our work on network troubleshooting at the intent level. Our solution provides capabilities to enable posing what-if type questions at the policy level –e.g. when a new input policy is introduced– to help answer reachability questions both at the policy and infrastructure level.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...
Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.
