Networking
How packets get from a wire into memory and out again: the NIC, Ethernet, PCIe, DMA, RSS and DPDK.
- Network Interface Cardinteractive 3D
An interactive, fully procedural 3D model of a dual-port 10GBASE-T PCIe NIC. Orbit it, click any part, lift the heatsink, and follow a packet from the RJ45 port to the RX queue.
NICPCIeDMARSSRX/TX queues - NIC to host memoryinteractive 3D
The first AxioByte system: the NIC in its PCIe slot, the lanes to the CPU, the memory channels to host memory — and DMA, the NIC writing each packet straight into a buffer in memory while no core copies it.
