DPDK Engineering & Consulting

Userspace networking at line rate.

I help telecom and technology companies build userspace dataplanes with DPDK — the same fast packet-processing techniques used in 4G/5G user-plane functions, tested from first packets on the wire to multi-queue hardware steering at 10G+.

4G / 5G Telecom

Fast packet processing where mobile networks demand it most

Modern 4G LTE and 5G networks move enormous volumes of subscriber traffic through the user plane — at the RAN edge, in the core, and inside virtualized network functions on standard servers. Every millisecond and every CPU cycle counts.

Why kernel networking falls short

Telecom user-plane workloads — GTP-U encapsulation, IPSec, QoS marking, DPI, and forwarding at the UPF, PGW, or vRouter — must sustain millions of packets per second with predictable latency. The Linux kernel stack adds overhead that makes consistent line-rate processing difficult on commodity hardware.

Where DPDK fits in 4G/5G

DPDK bypasses the kernel and drives NICs directly from userspace. It is widely used in NFV and cloud-native telco deployments for high-throughput user-plane functions, load balancers, session border controllers, and edge UPF instances where packets must be received, classified, and forwarded without per-packet syscall cost.

How my work helps telecom teams

The open-source tools and tutorials I have built map directly to problems telecom engineers face when bringing up, validating, and scaling user-plane software on real NICs.

  • Line-rate traffic generation — stress-test UPF and gateway paths before field deployment (validated at 10 Gbps on Intel XL710)
  • Multi-queue RX & RSS — spread subscriber flows across cores for 4G/5G throughput growth without redesigning the stack
  • Hardware flow steering (rte_flow) — redirect, drop, or isolate traffic classes in the NIC before packets hit the CPU
  • ACL & tuple classification — enforce subscriber or service policies on IP/port tuples at speed
  • Checksum & parse offload — free CPU cycles on GTP-U and UDP-heavy user-plane traffic
  • Telemetry & packet capture — observe live counters and record PCAPs during integration and fault isolation
  • Multiprocess dataplane — separate control-plane and user-plane processes, a common telco architecture pattern

Services

What I deliver for engineering teams

Practical DPDK work — not slide decks. I ship code, measure on real NICs, and leave your team with something maintainable.

DPDK application development

Custom high-speed dataplane apps: RX/TX pipelines, multi-lcore workers, mempools, and ring-based producer/consumer designs.

Performance optimization

Throughput and latency tuning — burst sizes, queue depth, NUMA placement, cache-friendly mbuf handling, and NIC statistics analysis.

Hardware offload & rte_flow

Program NIC classifiers to redirect, drop, or steer traffic in hardware. Validate rules per PMD (i40e, ixgbe, mlx5) before production.

Traffic tools & validation

Packet generators, dumpers, and lab harnesses to stress-test your stack at line rate with measurable, repeatable results.

Classification & filtering

Software ACL, RSS queue distribution, hardware packet-type parsing, and hybrid designs that minimize CPU per packet.

Architecture review & mentoring

Code reviews, DPDK onboarding for your team, telemetry integration, and multiprocess designs for control + dataplane separation.

Technical depth

Built on real dataplane experience

My work spans the full DPDK stack — EAL setup, ethdev configuration, mbuf lifecycle, and driver-specific behavior on production hardware.

  • DPDK EAL, ethdev, mempool, mbuf, ring, ACL, telemetry APIs
  • Intel XL710 / i40e PMD — tested in lab with loopback validation
  • IPv4/UDP checksum offload and L3/L4 hardware parsing
  • Receive Side Scaling (RSS) and Toeplitz hash verification
  • rte_flow: queue redirect, hardware drop, per-queue observability
  • Multiprocess primary/secondary communication via shared memory
  • Linux environment: hugepages, vfio-pci, dpdk-devbind, CMake builds

Typical engagements

  1. POC / spike Prove line-rate RX or TX on your target NIC in 1–2 weeks.
  2. Feature delivery Integrate offload, filtering, or steering into an existing product.
  3. Performance rescue Find packet loss, queue bottlenecks, and fix throughput regressions.
  4. Team enablement Pair with your engineers and transfer operational knowledge.
