Aeron Premium Aeron Transport Kernel Bypass

Overview

Aeron Transport Kernel Bypass is designed to unlock the full potential of your network by leveraging kernel bypass technologies. These technologies allow direct access to the TX/RX ring buffers of network cards, providing APIs designed for performance with zero copy semantics and real-time lock-freedom/wait-freedom. This significantly reduces CPU overhead and yields lower and more predictable latency.

Key Features

• Reduced CPU Overhead: By bypassing the kernel, CPU resources are freed up for critical tasks.
• Enhanced Latency Predictability: Consistent performance with lower and more predictable latency.
• Market-Competitive Throughput: Achieve high-speed execution with efficient APIs for accessing ring buffers.
• Flow and Congestion Control: Aeron provides flow and congestion control on top of its UDP implementation, avoiding the need for a full implementation for WAN usage.

Technical Details

• Kernel Bypass Extension: Aeron supports DPDK (Data Plane Development Kit) kernel bypass extension.
• Zero-Copy APIs: Efficient APIs for accessing ring buffers with zero copy and lock-free operations.
• Supported Network Cards: Optimized for Solarflare/Xilinx and NVidia/Mellanox network cards, including AWS Nitro instances.

Operational Considerations

• Supported Platforms: Available as an Aeron Premium feature.
• Dependencies: Requires specific network cards and drivers for optimal performance.
