DPDK-Based High-Performance Network

aNET leverages the Data Plane Development Kit to achieve significant performance improvements by moving network packet processing to userspace. This kernel-bypass approach eliminates context switching overhead and utilizes polling-mode drivers with huge page memory management, allowing for more efficient CPU utilization and higher packet processing rates.

Multiple Queues and Interrupt Binding For NICs

The system implements multiple queue support for network interface cards with intelligent interrupt binding to optimize I/O processing. Each physical NIC is configured with multiple receive and transmit queues mapped to specific CPU cores, enabling parallel packet processing and preventing any single core from becoming a bottleneck.

NUMA Node Affinity

aNET employs Non-Uniform Memory Access awareness to optimize resource allocation and data locality. The system automatically detects the NUMA topology and ensures virtual network components are allocated resources from the appropriate NUMA nodes, minimizing cross-node memory accesses and reducing memory latency for improved network performance.
