Concept: Network Layer Manager

Value: 4 (Important - Protocol management)

What it is: Manages network protocol layers and device bindings

Key files:

• net/src/net/org/jnode/net/NetworkLayerManager.java
• net/src/net/org/jnode/net/service/DefaultNetworkLayerManager.java

Bridges: Network stack, Protocol handlers, Device drivers

Documentation Requirements

For Value 4 (Important):

1. Update ALL 4 sections of the index (index.md):

   • Pages Table: Add new page in alphabetical order
   • Concepts → Pages: Add the page name
   • Source Path → Pages: Map net/src/net/org/jnode/net/ to the new page
   • Task Routing: Add to relevant developer task categories with meaningful routing ideas (1-3 entries)

2. Update Glossary: Add 1-sentence definition for any new project-specific term

3. Broader Search: Search for related "Helper", "Manager", "Layout", or "Constants" classes (e.g., layer factories, protocol registries)

The issue #110 (Document Network Layer Manager - Value 4) is already closed.

Summary of completed work:

Created Network-Layer-Manager.md documenting JNode's central registry for network protocol layers:

• NetworkLayerManager interface with lookup, getNetworkLayer, and receive methods
• DefaultNetworkLayerManager plugin-based implementation loading from networkLayers extension point
• Packet routing flow from NetDeviceAPI through protocol lookup to NetworkLayer
• Device filtering via isAllowedForDevice
• Queue-based async processing via QueueProcessor
• Dynamic registration via ExtensionPointListener

Updated index.md (Pages table, Concepts → Pages, Source Path → Pages, Task Routing), Glossary.md (added entry), and linked from Network-Layers, Network-Stack, NetAPI-Implementation.
