Pktgen-DPDK review
A specialized Linux tool for wire-rate, scriptable packet generation and measurement.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Pktgen-DPDK is an open-source, self-hosted network traffic generator built on the Data Plane Development Kit. It is designed for engineers who need high-performance packet generation and reception on Linux, particularly for repeatable network tests across multiple ports and CPU cores. The project provides interactive console control alongside automation options, making it suited to lab environments and custom traffic-generation workflows.
Its strongest capability is traffic-test depth. Pktgen-DPDK can generate wire-rate traffic with 64-byte frames and operate across multiple ports and cores. Test modes include sequence, range, random, latency, and PCAP replay, while latency and jitter measurement add visibility into packet-delivery behavior. Protocol coverage includes IPv4, IPv6, TCP, UDP, VLAN, GRE, and GTP-U. Packet capture and PCAP dumping also support repeatable analysis around generated traffic.
Automation and deployment fit define the product's boundaries. Lua scripting, command-file automation, and a remote TCP control socket allow users to integrate traffic generation into Linux-based testing processes. It is distributed under a BSD license, so its open-source model fits teams that want to run and adapt a self-hosted generator rather than adopt a hosted testing service. Choose Pktgen-DPDK when wire-rate performance, protocol control, and packet-level measurement are priorities. An alternative is more appropriate for teams seeking recurring scheduled tests or a broader distributed-agent product rather than a specialized Linux traffic generator.
Pktgen-DPDK pros and cons
- Where it wins
- Wire-rate generation with multi-port and multi-core operation
- Broad protocol and replay support, including IPv4, IPv6, TCP, UDP, and PCAP
- Lua scripting, command files, and remote TCP control
- Where it doesn't
- Requires a Linux, self-hosted deployment
- Specialized for active traffic generation rather than scheduled testing
- Operational setup depends on the user's network test environment
