What is OpenOnload?
OpenOnload® is a high performance network stack from Solarflare that dramatically reduces latency and CPU utilization, and increases message rate and bandwidth. OpenOnload runs on Linux and supports TCP/UDP/IP network protocols with the standard BSD sockets API, and requires no modifications to applications to use.
What is Ef_vi?
ef_vi is an API that gives applications access to the network adapter’s. datapath. That is, it can be used to send and receive raw Ethernet frames. directly from user-level.
What is DPDK Linux?
The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation. It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space.
What is kernel bypass Linux?
Kernel-bypass networking eliminates the overheads of in-kernel network stacks by moving protocol processing to userspace. The packet I/O is either handled by the hardware, the OS, or by userspace, depending on the specific kernel-bypass architecture in use.
What is solarflare card?
Solarflare, a maker of 10 Gigabit Ethernet server adapter cards for performance-obsessed companies like stock exchanges, hedge funds, and supercomputer centers, is turning its network interface cards into servers, more or less.
What is kernel bypass?
Is DPDK open source?
DPDK is licensed under the Open Source BSD License.
Why is DPDK needed?
DPDK provides a programming framework for x86, ARM, and PowerPC processors and enables faster development of high speed data packet networking applications. It scales from mobile processors, such as Intel Atom, to server-grade processors, such as Intel Xeon.
What is the use of DPDK?
What is eBPF Linux?
eBPF is a revolutionary technology with origins in the Linux kernel that can run sandboxed programs in an operating system kernel. It is used to safely and efficiently extend the capabilities of the kernel without requiring to change kernel source code or load kernel modules.
What is solarflare network?
Solarflare is a technology company who pride themselves on providing cutting edge extreme performance network interface cards (NICs), highly efficient software and comprehensive networking solutions.
How does kernel bypass work?
It works by completely taking over a network card, and implements a hardware driver in userspace. It’s done on a PCI device level with a form of userspace IO (UIO), by mmaping the device registers with sysfs. This allows for very fast operation, but it means the packets completely skip the kernel network stack.
Open Source (GPLv2.0 and BSD-2-Clause). OpenOnload comprises a user-level shared library that intercepts network- related system calls and implements the protocol stack, and supporting kernel modules.
