Services Layer

Service Layer

Function

The services layer implements several system services that are spawned by the kernel upon boot-up.

Design Principles

• Provides runtime processes to poll device sockets.
• Supports input and output streams to sockets.
• Sockets may be physical devices or IPC queues, allowing staged processing of streams.
