+NVLink is the protocol itself – a low-level, hardware-accelerated, point-to-point interconnect designed specifically for GPU-to-GPU/CPU communication. Protocol Stack	No TCP/IP, Ethernet, or InfiniBand. Uses proprietary NVLink Packet Protocol with minimal overhead. No TCP/IP, Ethernet, or InfiniBand. Uses proprietary NVLink Packet Protocol with minimal overhead.
