Our Core Expertise

Datacenters Software

  • HW/SW integration and offloads, including protocol offloads (CSUM, segmentation), zero-copy designs, traffic streams balancing (RSS): support, validation, profiling and optimization.
  • Implementation and adaptation of IPv6 stacks on multiple platforms.
  • BPF/eBPF-based network analyzers and performance enhancement systems implementation.
  • Network management for enterprise environments (CIM providers), multi-platform support (including Linux/Windows/ESX). Passing ESX CIMPAT certification.
  • Network drivers including DPDK PMD implementation, support and performance tuning for Linux/BSD/Solaris/ESX.
  • IOVP, NIC, SR-IOV, Vmware ESX certifications.
  • Upstreaming drivers to DPDK, FreeBSD, Linux Kernel and Illumos.
  • Solutions that allow to get higher performance from existing equipment by moving certain processing into userland context.
  • TCP/IP network stack performance/latency optimizations, including low level optimizations for x86/x86_64/Power 7/aarch64 architectures, tuning for multi-core and NUMA systems.
  • DPDK drivers development and optimization.
  • OpenOnload: key developers.

Network Performance Optimizations

Block Subsystem

  • Environments: Linux kernel, SPDK.
  • Understanding Linux internals (block i/o, scheduling, multithreading, synchronization, interrupts, memory management, filesystems, device drivers, virtio-block).
  • NVMe technology, including NVMe over TCP and NVMe over RDMA (RoCE).
  • Performance engineering (benchmarking, profiling, bottleneck research, latency optimizations).
  • Validation of storage solutions: Test suite development, passing UNH certification.
  • Hands-on experience with CEPH solutions, development of HW/SW-accelerated clients.
  • Implementation of fully automated test systems.
  • HW/Design validation on models including development of in-house HW-accurate C-based models integrating with QEMU for early prototyping.
  • Synchronous and asynchronous models including creation of HW system models.
  • Implementation of test results management systems for customer needs.
  • Internal products used for testing and validation: distributed test SDK/Engine, used in most complex POSIX API test suite, DPDK, NVMeoF, OVS, Home gateways, Filesystems and other test suites.

Validation and Testing

Optimization of existing solutions


Optimization of existing networking applications w/o need to rewrite them using custom network stacks - leads to many-fold growth of performance and huge costs savings.

Datacenter IO

Development of network/block solutions for high performance datacenters.

Migration to SPDK/DPDK

Replacement of network/block stacks in existing solutions by DPDK/SPDK based stack - leads to many-fold growth of performance and huge costs savings.

Migration to SPDK_DPDK (2)

Implementation of automatic test systems

Implementation of fully-automated test systems and results management systems capable of handling tens of millions of results.
