Why multi-versioning support in VPP rocks!

By Ray Kinsella | Jun 10 2022, TSC member Ray Kinsella has been blogging recently on VPP. This latest post describes how VPP auto-magically optimizes for the microprocessor generation on which it is running. This means that optimizations can be targeted at specific microprocessors, giving much finer granularity of optimization and better overall performance.

Guide to talking to applications from VPP

By Ray Kinsella | Jun 1 2022, TSC member Ray Kinsella has been blogging recently on VPP. His latest post describes how different kinds of applications can punt packets to or receive packets from VPP. Different applications will have different requirements, and operate at different levels of the OSI model. VPP is therefore equipped to support a number of different APIs to support these varying requirements. Some applications may require a simple raw packet interface, others will require stateful protocol support behind the BSD Sockets API. VPP always has a solution.

Using HPC instructions to accelerate

By Ray Kinsella | May 24 2022, TSC member Ray Kinsella has been blogging recently on VPP. His latest post describes how VPP is accelerated using SIMD instructions. Single instruction, multiple data (SIMD) instructions are commonly used to improve software efficiency by performing an operation on multiple buffers (data) in parallel. This can improve ‘instructions per cycle’ (IPC) a common metric that describes the efficiency of software. SIMD instructions are most commonly used to accelerate High Performance Computing (HPC) workloads, however re-purposes these to accelerate networking workloads.

A Terabit Secure Network Data-Plane

By The linux foundation | Apr 6 2021, (“Fido”), relentlessly focused on data IO speed and efficiency supporting the creation of high performance, flexible, and scalable software defined infrastructures, today announced support for terabit rates of IPsec, as well as a billion packets per second of IPv4 routing at scale. Architectural improvements in 3rd Gen Intel Xeon Scalable processors including PCIe bandwidth increase and overall decrease in cycles-per-packet due to CPU micro-architecture improvements combined with software deliver significant price-performance gains for both cloud- and appliance-based software router and secure networking solutions. offers the software defined infrastructure developer community a landing site with multiple projects fostering innovations in software-based packet processing towards the creation of high-throughput, low-latency, and resource-efficient I/O services suitable to many architectures (x86, ARM, and PowerPC) and deployment environments (bare-metal, VM, …

CuVPP: Filter-based Longest Prefix Matching in Software Data Planes

By Minseok Kwon, Krishna Prasad Neupane, John Marshall, M. Mustafa Rafique | Sep 15 2020,

IEEE Cluster 2020 Kobe – The paper titled “CuVPP: Filter-based Longest Prefix Matching in Software Data Planes” wins “Best Papers” award at IEEE Cluster 2020 on September 15th. Programmability in network switches (or data planes) has become increasingly important with increasing network virtualization in the Internet infrastructure and large-scale data centers. A critical challenge in data plane programmability is to maintain high-speed packet processing performance with ever increasing link speed to hundreds of Gbps or Tbps. Another challenge is the rapid growing routing table size, e.g., more than 500,000 entries. We implement CuVPP as part of the Real Software Switch VPP and provide a comprehensive evaluation using popular alternative approaches with realistic data sets for network prefixes and traffic.

Fast Data Project’s Vector Packet Processor (VPP) Release 20.05

By Linux Foundation | Jul 23 2020,

SAN JOSE – (“Fido”) – an open source project within The Linux Foundation’s LF Networking (LFN) – announced the availability of Vector Packet Processor (VPP) software release 20.05. The VPP (Vector Packet Processor) release 20.05 is now available. VPP continues to be relentlessly focused on performance. In addition, VPP continues to add features. All this without sacrificing packet throughput. In this article we highlight some remarkable performance numbers, point to some of the features added in 20.05 and then point to some articles that have been published in the past 5 months.
