HIPC (Horizon Inter-Process Communication) is a custom IPC implementation tailored for the Horizon OS.
There are two protocols over [[#HIPC|HIPC]]:
* [[#CMIF|CMIF]]: Command Interface (?). Supports session management with domains and dynamic multiplexing of services.
* [[#TIPC|TIPC]]: Tiny IPC. Simple and lightweight protocol.
[[#CMIF|CMIF]] is universally used for virtually almost all Switch services. [[#TIPC|TIPC]] is only used by the [[Services_API|Service Manager]] and [[PGL_services|pgl]].
