1/9/2024 0 Comments Netmap vs dpdkTeam is working on creating a DPDK PMD for 16-core OCTEON-III CN7360 PCIe NIC card. DPDK PMD for OCTEON-III and OCTEON-TX PCIe NIC The QuickAssist-AES driver can potentially also be used for pfSense and other firewalls based on 10.3 and higher versions. This is being utilized by our Customer for their FreeBSD IPSec VPNs both CPE and Concentrator. The AES-CBC performance results as checked on C2358 (4-core) and C2758 (8-core) were substantially better than SW path. Our Developers completed a port QuickAssist AES driver on FreeBSD 10.3 and 11.0, for use on C2000-Rangeley CPU series from Intel. QuickAssist Drivers port to FreeBSD for Intel Rangeley series Allowing for a Transpare seamless switch-over on 600 Pop Nodes for Customer. All Features and Controls were fully ported, tested with Automated Scripts, fuzz testing and High Packet rates using Traffic Generators. The Packet path saw a 2500% speed gain as compared to initial User-space stack. Our team ported Customer's proprietary GRE encaps features, into a DPDK Fast-path application in User-space deployed on dedicated CPU cores. DPDK adaption of Custoer's proprietary GRE features for Fast-path Acceleration See here for information on the Offload Stack. Stack has been tested and deployed with OpenWRT and VyOS Control-Planes. GRE offload feature is also a module addition to the Stack. IPSec Offload is also available, which can be added as a Module to this Stack. The Stack performs majority of IPv4 and IPv6 Packet Forwarding functions as well as NAT and Firewall features. Earlier the same Accelerator Stack was also enabled for OCTEON-III and OCTEON-TX2 Multi-core CPUs using Simple-Exec (SE, SE2) execution environments. Team completed its Network Offload Stack for use on Intel x86 Multi-core CPUs using DPDK framework. All these are frameworks and Toolkits to provide an optimized data-path for different OS environments (Linux / FreeBSD), to help a vendor achieve many folds of performance gains.ĭPDK Network Fast-Path Offload Accelerator for IPv4, v6, Firewall, NAT, IPSec, GRE, Traffic-Shaping We are also engaged with customers interested in Vector Packet Processing framework. We have worked on multiple projects involving DPDK, QuickAssist and NetMap. Paxym's team has extensive working experience with many flavors of packet processing acceleration frameworks (aka Fast-Path). Within various techniques, DPDK has been widely used because of its more thorough isolation from kernel scheduling and active community support.į-Stack is an open source network framework with high performance based on DPDK, include an user space TCP/IP stack(port FreeBSD 11.0 stable), Posix API(Socket, Epoll, Kqueue), Progamming SDK(Coroutine) and some apps(Nginx, Redis) interface.DPDK, NetMap, VPP, QuickAssist are technologies used in modern Router architectures to provide accelerated software packet processing path. Furthermore, kernel bypass can achieve higher performance with multi optimizing methods. Therefore, kernel bypass can avoid performance bottlenecks caused by kernel packet copy, thread scheduling, system calls and interrupt. The main idea of kernel bypass is that Linux is only used to deal with control flow, all data streams are processed in user space. There are various similar technologies appear, such as DPDK, NETMAP and PF_RING. However, the rapid development of the Internet needs high performance of network processing, kernel bypass has caught more and more attention. With the rapid development of NIC, the poor performance of data packets processing with Linux kernel has become the bottleneck.
