The Linux Block Layer - Built for Fast StorageKernel TLV
The arrival of flash storage introduced a radical change in performance profiles of direct attached devices. At the time, it was obvious that Linux I/O stack needed to be redesigned in order to support devices capable of millions of IOPs, and with extremely low latency.
In this talk we revisit the changes the Linux block layer in the
last decade or so, that made it what it is today - a performant, scalable, robust and NUMA-aware subsystem. In addition, we cover the new NVMe over Fabrics support in Linux.

This talk focuses on the lessons learned in creating the Brocade vRouter using DPDK. It covers some of the architecture, locking and low level issues that all have to be dealt with to achieve 80 Million packets per second forwarding.
Ariel Waizel discusses the Data Plane Development Kit (DPDK), an API for developing fast packet processing code in user space.
* Who needs this library? Why bypass the kernel?
* How does it work?
* How good is it? What are the benchmarks?
* Pros and cons
Ariel worked on kernel development at the IDF, Ben Gurion University, and several companies. He is interested in networking, security, machine learning, and basically everything except UI development. Currently a Solution Architect at ConteXtream (an HPE company), which specializes in SDN solutions for the telecom industry.

Building Network Functions with eBPF & BCCKernel TLV
eBPF (Extended Berkeley Packet Filter) is an in-kernel virtual machine that allows running user-supplied sandboxed programs inside of the kernel. It is especially well-suited to network programs and it's possible to write programs that filter traffic, classify traffic and perform high-performance custom packet processing.
BCC (BPF Compiler Collection) is a toolkit for creating efficient kernel tracing and manipulation programs. It makes use of eBPF.
BCC provides an end-to-end workflow for developing eBPF programs and supplies Python bindings, making eBPF programs much easier to write.
Together, eBPF and BCC allow you to develop and deploy network functions safely and easily, focusing on your application logic (instead of kernel datapath integration).
In this session, we will introduce eBPF and BCC, explain how to implement a network function using BCC, discuss some real-life use-cases and show a live demonstration of the technology.

Using eBPF for High-Performance Networking in CiliumScyllaDB
The Cilium project is a popular networking solution for Kubernetes, based on eBPF. This talk uses eBPF code and demos to explore the basics of how Cilium makes network connections, and manipulates packets so that they can avoid traversing the kernel's built-in networking stack. You'll see how eBPF enables high-performance networking as well as deep network observability and security.
Integration of OVS in OpenWrt wireless network and investigation of SDWMNNazmul Hossain Rakib
OpenFlow managed Software Defined Network (SDN) and Wireless Mesh Network (WMN) are being an emerging technology for their autonomous functionality and economic feasibility. SDN is somehow defined as next generation technology which let the network configure, optimize and heal centrally using artificial intelligence. WMN has been adopted by several applications because of its promising functionality. In this research, applicability of SDN on WMN has been studied as well as the decentralized controller mechanism over SDWMN (Software Defined Wireless Mesh Network). First of all, two types of Wireless connectivity (AD Hoc and WDS) has been researched using OpenWrt configured SDN. Then probability and availability of WMN using SDN has been investigated. Finally, some solutions has been tried to figure out for the further future implementation of SDWMN.
Cilium - Container Networking with BPF & XDPThomas 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.
High-Performance Networking Using eBPF, XDP, and io_uringScyllaDB
In the networking world there are a number of ways to increase performance over naive use of basic Berkeley sockets. These techniques have ranged from polling blocking sockets, non-blocking sockets controlled by Epoll, all the way through completely bypassing the Linux kernel for maximum network performance where you talk directly to the network interface card by using something like DPDK or Netmap. All these tools have their place, and generally occupy a space from convenience to performance. But in recent years, that landscape has changed massively.. The tools available to the average Linux systems developer have improved from the creation of io_uring, to the expansion of bpf from a simple filtering language to a full-on programming environment embedded directly in the kernel. Along with that came something called XDP (express datapath). This was Linux kernel's answer to kernel-bypass networking. AF_XDP is the new socket type created by this feature, and generally works very similarly to something like DPDK. History lessons out of the way, this talk will look into, and discuss the merits of this technology, it's place in the broader ecosystem and how it can be used to attain the highest level of performance possible. This talk will dive into crucial details, such as how AF_XDP works, how it can be integrated into a larger system and finally more advanced topics such as request sharding/load balancing. There will be detailed look at the design of AF_XDP, the eBpf code used, as well as the userspace code required to drive it all. It will also include performance numbers from this setup compared to regular kernel networking. And most importantly how to put all this together to handle as much data as possible on a single modern multi-core system.
Accelerating Envoy and Istio with Cilium and the Linux KernelThomas Graf
This talk will provide an introduction to injection options of Envoy and then deep dive into ongoing Linux kernel work that enables injecting Envoy while introducing as little latency as possible.
The servicemesh and the sidecar proxy model are on a steep trajectory to redefine many networking and security use cases. This talk explains and demos a new socket redirect Linux kernel technology that allows running Envoy with similar performance as if the sidecar was linked to the application using a UNIX domain socket. The talk will also give an outlook on how Envoy can use the recently merged kernel TLS functionality to gain access to the clear text payload transparently for end to end encrypted applications without requiring to decrypt and re-encrypt any data to further reduce the overhead and latency.

Stacks and Layers: Integrating P4, C, OVS and OpenStackOpen-NFP
Smart Network Interface Cards (SmartNICs) are increasingly being deployed in cloud data centers to offload inline network processing tasks from server CPUs, thereby improving system throughput while freeing up server CPU cycles for application processing. The match/action and tunnel handling semantics of SmartNIC datapaths can be either expressed directly in the P4 language, be defined by virtual switching software like Open vSwitch (implementing the semantics of a specification like OpenFlow), or by using a combination of these. This presentation compares these approaches, considering aspects like the expressiveness and performance of the resulting datapath as well how these datapath variants can be integrated into existing cloud management systems (e.g. OpenStack).

Sharing High-Performance Interconnects Across Multiple Virtual Machinesinside-BigData.com
In this deck from the Stanford HPC Conference, Mohan Potheri from VMware presents: Sharing High-Performance Interconnects Across Multiple Virtual Machines.
"Virtualized devices offer maximum flexibility: sharing of hardware between virtual machines, the use of VMware vMotion to handle migration and take snapshots. However, when performance is the most critical requirement there are other options. VMware Direct Path I/O delivers excellent performance, but only for a single virtual machine. Single root I/O virtualization (SR-IOV), on the other hand, offers the performance of pass-through mode while allowing devices to be shared by multiple virtual machines.
This session introduces SR-IOV, explains how it is enabled in VMware vSphere, and provides details of specific use cases that important for machine learning and high-performance computing. It includes performance comparisons that demonstrate the benefits of SR-IOV and information on how to configure and tune these configurations."

Dataplane programming with eBPF: architecture and toolsStefano Salsano
eBPF is definitely a complex technology. Developing complex systems based on eBPF is challenging due to the intrinsic limitations of the model and the known shortcomings of the tool chain.
The learning curve of this technology is very steep and needs continuous coaching from experts. This tutorial will investigate:
What is eBPF and why it has gained a prominent position among the solutions to improve the packet processing performance in Linux/x86 nodes. We will shortly present some important use case scenarios for eBPF, like Kubernetes’ Cilium
The architecture of eBPF and its programming toolchain (e.g. bcc
What are the frameworks for eBPF programming, such as Polycube and InKeV.
How to make eBPF programming easier, more flexible and modular with HIKe/eCLAT
How to implement a custom application logic in eBPF with eCLAT using a python-like script
How to extend the framework and develop new modules
Packet processing in the fast path involves looking up bit patterns and deciding on an actions at line rate. The complexity of these functions at Line Rate, have been traditionally handled by ASICs and NPUs. However with the availability of faster and cheaper CPUs and hardware/software accelerations, it is possible to move these functions onto commodity hardware. This tutorial will talk about the various building blocks available to speed up packet processing both hardware based e.g. SR-IOV, RDT, QAT, VMDq, VTD and software based e.g. DPDK, Fd.io/VPP, OVS etc and give hands on lab experience on DPDK and fd.io fast path look up with following sessions. 1: Introduction to Building blocks: Sujata Tibrewala

Convergence of device and data at the Edge CloudMichelle Holley
Ever growing need of Intelligent Systems evolves analytics and decision making into AI with Machine Learning as tools for knowledge assimilation. What is essential for ML is a form of data that has inherent information that can be translated to useful information (intelligence) for decision making. IoT is the key for intelligent systems as they collect data at every end point. They are like ends of neuron network in human body. And the data collected has to be refined for decision making as it traverses up to the brain (AI Cloud) – like lymph nodes we have Edge Clouds. We will explore in this short talk two aspects of such IoT infrastructure where you have lossy network for IoTs, gateway options for device data and how it can seamlessly integrate with Edge Cloud Networks. We will review such protocols as Wireless Mesh, programmable gateways and extension of overlays into the Cloud.
Speaker: Murali Rangachari, Futurewei Technologies
The rapid growth of data requires advanced intelligence closer to the endpoints that are both generating and consuming data. To capture and accelerate this opportunity, the powerful data processing and analytics capabilities that have traditionally lived in the heart of the data center must be strategically placed closer-and-closer to the data generating and consuming endpoints, at the “edge.” This presentation will look at the opportunities facing the Edge ecosystem and show how Intel via its Intel Network Builders’ Network Edge Ecosystem program is helping the community capitalize on this opportunity and accelerate the deployment of Edge solutions.

The concept of service mesh is one of the new technologies that have grown up around the container and micro-service model over the last couple of years, and Istio is the latest entry into this space. As Istio was recently included as an incubated project in the CNCF, many companies are now looking to it to provide a set of key functions to accelerate their micro-service application management model. Istio enables bi-directional authentication and security of service communication via TLS based authentication and encryption, and at the same time is able to capture application level communication statistics, improving the application development team's visibility into the otherwise difficult to track communication patterns. In this way, Istio acts like an application level network, riding across the underlying capabilities of Kubernetes CNI based networks and network policy. We will implement Istio on a GKE kubernetes cluster, and instrument a simple application to get better insight into how Istio provides its capabilities.

Accelerating Virtual Machine Access with the Storage Performance Development ...Michelle Holley
Abstract: Although new non-volatile media inherently offers very low latency, remote access
using protocols such as NVMe-oF and presenting the data to VMs via virtualized interfaces such as virtio
adds considerable software overhead. One way to reduce the overhead is to use the Storage
Performance Development Kit (SPDK), an open-source software project that provides building blocks for
scalable and efficient storage applications with breakthrough performance. Comparing the software
paths for virtualizing block storage I/O illustrates the advantages of the SPDK-based approach. Empirical
data shows that using SPDK can improve CPU efficiency by up to 10 x and reduce latency up to 50% over
existing methods. Future enhancements for SPDK will make its advantages even greater.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Vector Packet Processing (VPP) Introduction
Vector Packet Processing is the open source high-performance packet
processing software, in development since 2002.
Open source version of Cisco’s VPP Technology.
The VPP platform provides a production-quality switch/router functionality.
It uses Data Plane Development Kit (DPDK) to take advantage of fast I/O.
DPDK provides fast packet processing libraries and user space drivers. It can
receive and send packets with the minimum number of CPU cycle by
bypassing the kernel and use a user poll mode driver.
7. 7
Vector Packet Processing (continued)
• Packet Processing Graph: VPP reads a large number of packets (called
vector) from the network I/O layer (DPDK input), then passes it to the packet
processing graph where each node provides a specific network function to
packets and each directed edge indicates the next network function that
handle the packets.
• Handle packet processing in batches, up to 256 packets at a time. The whole
vector of packets is processed by a graph node. When done, the whole vector
is moved to the next graph node.
• When a vector of packets is handled by a node, only the first packet in the
batch needs to load the CPU’s instructions to the cache; the rest of the
packets can benefit the from the instruction already in the cache.
8. 8
Vector Packet Processing (continued)
VPP architecture is flexible to allow users to create new nodes, enter them into
the packet processing graph, and rearrange the graph.
Run in user space.
VPP can be used on bare metal, virtual machines (VMs), or containers.
Run on x86, ARM, Power* architecture.
