While XDP is less complex to offload than other forms of kernel functionality due to the fact that it sits at the bottom of the stack, there are a number of items that lead to complexity when dealing with XDP offload. This talk will explore some of the ideas around how to implement these concepts as well as share some of the results we have seen while implementing offload on a 32 bit architecture.

With the rise of cloud-native principles, applications are increasingly able to take advantage of diverse, specialized and distributed infrastructure. The emergence of Edge Cloud solutions promises faster and more immersive application experiences, as well as infrastructure primitives for 5G, IoT, mobility, and more. However, this new resource comes with space and power constraints that can only be overcome by using new disaggregated architectures that leverage network acceleration and optimally sized CPUs. The session will highlight how the capabilities unleashed by hardware offload of eBPF in edge cloud microservers will enable developers to efficiently leverage the massive amounts of data on the edge and to create next-generation real-time applications.

Using Network Acceleration for an Optimized Edge Cloud Server Architecture

We present a new open source project which provides IPv6 networking for Linux Containers by generating programs for each individual container on the fly and then runs them as JITed BPF code in the kernel. By generating and compiling the code, the program is reduced to the minimally required feature set and then heavily optimised by the compiler as parameters become plain variables. The upcoming addition of the Express Data Plane (XDP) to the kernel will make this approach even more efficient as the programs will get invoked directly from the network driver.

Cilium - Fast IPv6 Container Networking with BPF and XDP

Thomas Graf

This talk demonstrates that programmability and performance does not require user space networking, it can be achieved in the kernel by generating BPF programs and leveraging the existing kernel subsystems. We will demo an early prototype which provides fast IPv6 & IPv4 connectivity to containers, container labels based security policy with avg cost O(1), and debugging and monitoring based on the per-cpu perf ring buffer. We encourage a lively discussion on the approach taken and next steps.

Cilium - Container Networking with BPF & XDP

Thomas Graf

Cilium is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. At the foundation of Cilium is a new Linux kernel technology called BPF, which enables the dynamic insertion of powerful security visibility and control logic within Linux itself. Because BPF runs inside the Linux kernel itself, Cilium security policies can be applied and updated without any changes to the application code or container configuration.

Unikernels have been demonstrated to deliver excellent performance in terms of throughput and latency, while providing high isolation. However they have also been shown to underperform in some types of workloads when compared to a generic OS like Linux. In this presentation, we demonstrate that certain types of workloads - web servers, microservices, and other stateless and/or serverless apps - can greatly benefit from OSv optimized networking stack and other features. We describe number of experiments where OSv outperforms Linux guest: most notably we note 1.6 throughput (req/s) and 0.6 latency improvement (at p99 percentile) when running nginx and 1.7 throughput (req/s) and 0.6 latency improvement (at p99 percentile) when running simple microservice implemented in Golang. We also show that OSv' small kernel, low boot time and memory consumption allow for very high density when running server-less workloads. The experiment described in this presentation shows we can boot 1,800 OSv microVMs per second on AWS c5n.metal machine with 72 CPUs (25 boots/sec on single CPU) with guest boot time recorded as low as 8.98ms at p50 and 31.49ms at p99 percentile respectively. Lastly we also demonstrate how to automate the build process of the OSv kernel tailored exactly to the specific app and/or VMM so that only the code and symbols needed are part of the kernel and nothing more. OSv is an open source project and can be found at https://github.com/cloudius-systems/osv.

Berkeley Packet Filter is an old friend for most people that deal with network under Linux. But its extended version eBPF is completely redefining the scope of usage and interaction with the kernel. It can indeed be used to instrument most parts of the kernel. This goes from network tracing to process or I/O monitoring. This talk will provide an overview of eBPF, from concept to tools like BCC. It will then focus on XDP for eXtreme Data Path and the possible applications in term of networking provided by this new framework. Eric Leblond, Stamus Network

Container runtimes cause Linux to return to its original purpose: to serve applications interacting directly with the kernel. At the same time, the Linux kernel is traditionally difficult to change and its development process is full of myths. A new efficient in-kernel programming language called eBPF is changing this and allows everyone to extend existing kernel components or glue them together in new forms without requiring to change the kernel itself.

As containers are being deployed as part of multi tenant clusters, virtual multi layer switches become essential to interconnect containers while providing isolation guarantees. Assigning tenants their own private networks requires stateful network address translation (NAT) implemented in a scalable architecture to expose containers to public networks. Existing virtual switches integrated into the Linux kernel did not support stateful NAT so far. This presentation introduces a new virtual NAT service deployable as container built using existing kernel functionality such as network namespaces, routing rules and Netfilter to provide NAT services to existing virtual switches such as Open vSwitch and the Linux bridge but also the core L3 layer of Linux.

The Linux packet filtering technology, iptables, has its roots in times when networking was relatively simple and network bandwidth was measured in mere megabits. Emerging technologies, such as distributed NAT, overlay networks and containers require enhanced functionality and additional flexibility. In parallel, the next generation of network cards with speeds of 40Gb and 100Gb will put additional pressure on performance. In the upcoming Red Hat Enterprise Linux 7, a new dynamic firewall service, FirewallD, is planned to provide greater flexibility over iptables by eliminating service disruptions during rule updates, abstraction, and support for different network trust zones. Additionally, a new virtual machine-based packet filtering technology, nftables, addresses the functionality and flexibility requirements of modern network workloads. In this session you’ll: Deep dive into the newly introduced packet filtering capabilities of Red Hat Enterprise Linux 7 beta. Learn best practices.

Short The growing amount of data captured by sensors and the real time constraints imply that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in Arm-based platforms provide an unprecedented opportunity for new intelligent devices. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators. Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, accelerator solutions, and will describe the efforts underway in the Arm ecosystem. Abstract The dramatically growing amount of data captured by sensors and the ever more stringent requirements for latency and real time constraints are paving the way for edge computing, and this implies that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in recent Arm-based platforms provides an unprecedented opportunity for new intelligent devices with ML inference. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators. Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, model description formats, accelerator solutions, low cost development boards and will describe the efforts underway to identify the best technologies to improve the consolidation and enable the competitive innovative advantage from all vendors. Audience The session will be useful for executives to engineers. Executives will gain a deeper understanding of the issues and opportunities. Engineers at NN acceleration IP design houses will take away ideas for how to collaborate in the open source community on their area of expertise, how to evaluate the performance and accelerate multiple NN frameworks without modifying them for each new IP, whether it be targeting edge computing gateways, smart devices or simple microcontrollers. Benefits to the Ecosystem The AI deep learning neural network ecosystem is starting just now and it has similar implications with open source as GPU and video accelerators had in the early days with user space drivers, binary blobs, proprietary APIs and all possible ways to protect their IPs. The session will outline a proposal for a collaborative ecosystem effort to create a common framework to manage multiple NN accelerators while at the same time avoiding to modify deep learning frameworks with multiple forks.

“Delivering a well working distribution is hard. There are a lot of different hardware platforms that need to be verified and the software stack is in a big flux during development phases. In rolling releases, this gets even worse, as nothing ever stands still. The only sane answer to that problem are working Continuous Integration tests. The SUSE way to check whether any change breaks normal distribution behavior is OpenQA. Using OpenQA we can automatically run tests that hard working QA people did manually in the old days. That way we have fast enough turnaround times to find and reject breaking changes This session shows how OpenQA works, what pitfalls we had to make ARM work with OpenQA and what we’re doing to improve it for ARM specific use cases.”

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.

Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.
