Linux kernel networking

The Linux family of operating systems is based on this kernel and deployed on both.Linux Kernel Networking Sub-system - part1 Video Contents: 1.Kernel bypass proponents like to argue that the server networking performance needed in SDN and NFV applications can be achieved using high-performance x86 CPU cores, and therefore traditional NICs are all that are needed.

Clone with HTTPS Use Git or checkout with SVN using the web URL.Unfortunately the speed of vanilla Linux kernel networking is not.

Linux Kernel 4.4.32 LTS Adds Networking Improvements

The ability to offload these compute-intensive networking functions to the SmartNIC brings higher levels of performance and security to VMs, increases the number of applications that can be delivered per server, and provides an overall boost in data center efficiency.

For example, there are implementations of Open vSwitch and OpenContrail that use DPDK as a kernel bypass approach.

With parallel networking stacks comes a seemingly endless list of security, manageability, robustness, hardware vendor lock-in, and protocol compatibility issues.

Kernel bypass - Cloudflare Blog

Why, then, have so many networking companies been so eager to bypass the Linux kernel -- or more specifically, the Linux kernel networking stack.Rather, intensive network processing tasks in the Linux kernel networking stack need to be offloaded to SmartNICs in a vendor agnostic way, instead of using implementations that result in parallel, redundant networking stacks.What could be so wrong with the networking packet arteries in the Linux kernel that motivates so many of us to bypass them.

The right way to solve the two problems above would be to find ways to accelerate performance of the kernel networking stack transparently, using smart networking hardware, and without any vendor lock-in.

Netronome Kernel bypass challenges The challenges related to adopting parallel stacks outside of the kernel networking stack are obvious to datacenter operators challenged with scaling their infrastructure to a very large number of servers.Linux Kernel Networking: Implementation and Theory takes you on a guided in-depth tour of the current Linux networking implementation and the theory behind it.

Table of Contents. 1. Purpose and Audience for This Book. and:.Given that servers consume as much as 60 percent of total datacenter infrastructure costs, the ability to support greater workloads per server using SmartNICs promises significant savings.SmartNICs are NICSs (network interface cards) that are programmable, enabling the vendors who provide such products to innovate server networking hardware at the speed of software -- a practical requirement in modern software-defined and NFV-enabled datacenter infrastructure.First, the kernel networking stack is too slow -- and the problem is only getting worse with the adoption of higher-speed networking in servers and switches (10GbE, 25GbE, and 40GbE today, and rising to 50GbE and 100GbE in the near future).More recently, DPDK (Data Plane Development Kit) has been used in some applications to bypass the kernel, and then there are new emerging initiatives such as FD.io (Fast Data Input Output) based on VPP (Vector Packet Processing).
