Conversely, introduces a modular, multi-threaded architecture by decoupling the control plane from the data plane. The operating system utilizes a hardened Linux kernel as its foundation. Classic Cisco IOS is modularized to run as a separate daemon—called the IOS Daemon (IOSd) —on top of this underlying Linux substrate.

The spa designation stands for . This means the binary contains cryptographic signatures verified by the hardware’s bootloader to ensure authenticity and protect against tampering or supply-chain malware injection. 4.
