Demystifying the Performance of XDP BPF

2019 IEEE Conference on Network Softwarization (NetSoft), 2019
High packet rates at $\geq 10\ \mathrm{GBit}/\mathrm{s}$ challenge the packet processing performance of network stacks. A common solution is to offload (parts of) the user-space packet processing to other execution environments, e.g., into the device driver (kernel-space), the NIC or even from virtual machines into the host operating system (OS), or ...

Explicit data placement (XDP)

ACM SIGPLAN Notices, 1993
The ability to represent, manipulate and optimize data movement between devices such as processors in a distributed memory machine, or between global memory and processors in a shared memory machine, is crucial in generating efficient code for such machines.

Efficient Network Monitoring Applications in the Kernel with eBPF and XDP

2021 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2021
Continuous traffic monitoring and analytics are fundamental to the operation of today?s networks. Network telemetry allows for performing fine-grained analytics on network flow or packet records for various use cases including intrusion detection and traffic engineering.

Understanding XDP Through Imaging, Pathology, and Genetics

International Journal of Neuroscience, 2010
The X-linked dystonia-parkinsonism (XDP) is a severe, progressive, adult-onset, X-linked endemic disorder in Filipinos, which is characterized by dystonic movements that start in the third or fourth decade, and replaced by parkinsonism beyond the 10th year of illness.

XDP

Proceedings of the twenty-sixth SIGCSE technical symposium on Computer science education, 1995
XDP is a simplified interface to the DP distributed programming library. I describe its use in a course on workstation programming, a pragmatic course whose mission is to cover concurrent programming, graphical user interfaces and event driven programming as well as network and distributed computing.

InXpect: Lightweight XDP Profiling

Proceedings of the 3rd Workshop on eBPF and Kernel Extensions
The eBPF eXpress Data Path (XDP) allows high-speed packet processing applications. Achieving high throughput requires careful design and profiling of XDP applications. However, existing profiling tools lack eBPF support. We introduce InXpect, a lightweight monitoring framework that profiles eBPF programs with fine granularity and minimal overhead ...

Understanding Delays in AF_XDP-Based Applications

International audiencePacket processing on Linux can be slow due to its complex network stack. To solve this problem, there are two main solutions: eXpress Data Path (XDP) and Data Plane Development Kit (DPDK).

Clinical evaluation of the xDP output compression strategy for cochlear implants

European Archives of Oto-Rhino-Laryngology, 2015
Technological advances in the domain of digital signal processing adapted to cochlear implants (CI) are partially responsible for the ever-improving outcomes observed with this neural prosthesis. The goal of the present study was to evaluate audiometric outcomes with a new signal processing strategy implemented in Oticon Medical-Neurelec cochlear ...

Processing of Electron Diffraction Patterns with the XDP Program

2012
Electron crystallography using two-dimensional crystals of membrane protein can provide high-resolution structure of a membrane protein within a lipid bilayer. With this technique, it is advantageous to use electron diffraction patterns to collect accurate intensities of the structure factors at high resolution.
