The pktgen software package for Linux is a popular tool in the networking community for generating traffic loads for network experiments. Pktgen is a high-speed packet generator, running in the Linux kernel very close to the hardware, thereby making it possible to generate packets with very little processing. In many cases, target applications can not reach line rate with 64-byte packets. If an expensive packet generator is not available, a good alternative exists based on DPDK - pktgen-dpdk. References; Prerequisites; Where to Get; Installation; Simple Commands to Build pktgen-dpdk; Tuning; Test Setup. Based on this answer it seems that pktgen sends packets below the packet capture hooks and it is not possible to see outgoing packets, untill and unless we modify the working of pktgen code. If anyone has a different suggestion please let me know. Thanks. 4 min - Uploaded by Intel SoftwareIn this video you'll build and launch two Docker containers that use Open vSwitch with DPDK.

Our measurement tests have been devoted to two main issues: the first was to evaluate the PktGen maximum performance (see Fig. 4), and the second was to compare PktGen with a software tool running on a high-end PC (Fig. 5). The PktGen maximum performance has been evaluated. 最近在做NFV相关的优化工作。在进行优化过程中需要对优化结果进行实时测试,以来确定优化手段是否有效果。由于公司并没有专业的发包机。而传统的netperf/iperf在10G场景下,64的小包很难发到限速。所以转而寻找其他工具来进行代替。刚好遇到了DPDK-Pktgen这个工具,完美的解决了我遇到的问题。 Common functions used by pktgen scripts # - Depending on bash 3 (or higher) syntax # # Author: Jesper Dangaaard Brouer # License: GPL ## -- General shell logging cmds -- function err() { local exitcode=$1 shift echo "ERROR: $@" >&2 exit $exitcode } function warn() { echo "WARN : $@" >&2 } function info() { if [[ -n. Hi, I've been using DPDK pktgen 2.8.0 (built against DPDK 1.8.0 libraries) to send traffic on a server using an Intel 82599 (X520-2). Traffic gets sent out port 1 through another server which also an Intel 82599 installed and is forwarded back into port 0. When I send using a single source and destination IP address, this works. pktgen. The pktgen kernel module (net/core/pktgen.c) can generate packets at very high speed. Monitoring and controlling is done via writing to /proc/net/pktgen entries. For “HOWTO for the linux packet generator" see Documentation/networking/pktgen.txt. Therefore, in our study, we chose to use Pktgen (detailed in section to avoid the interference of upper layer protocol processing and when the TCP performance is studied, we focused on how various optimizations affect the SR-IOV performance in terms of the bandwidth efficiency. 3 Experimental Setup The testbed we use. Here is some more information about Pktgen that others may want to know: At this point Pktgen is just a simple L2/L3 (UDP/TCP/IPv4 with some IPv6 support) traffic generator and does not have a network or any kind of state keeping. Mostly useful for sending traffic for performance testing and some other packet type testing. pktgen.c in snake-os located at /kernels/linux-2.6.16-gazineu/net/core.
