Auxiliary Architecture

This diagram shows the supporting components around transport handling and session management.

Important responsibilities in this area include:

• decoding WAMP frames from the negotiated serializer
• accepting the client-supplied HELLO realm as session metadata
• negotiating authentication challenges and AUTHENTICATE handling
• assigning and tracking WAMP session identifiers
• attaching transport principal, auth metadata, and client-supplied realm information to messages
• publishing lifecycle events such as session establishment and disconnect

These auxiliary pieces are shared by the higher-level broker and dealer pipelines.
