Data Plane

The Secure Low-Latency Interactive Messaging (SLIM) data plane implements an efficient message routing and delivery system between agents.

Message Format

SLIM messages use a channel-based addressing scheme for content routing:

message SLIMMessage {
    string channel_id = 1;
    string message_id = 2;
    bytes payload = 3;
    MessageMetadata metadata = 4;
}

Connection Table

The connection table maintains agent connectivity information by mapping channel IDs to connected agents and tracking connection state and capabilities.

Forwarding Table

The forwarding table implements intelligent message routing by implementing the following:

  • Maps message patterns to delivery strategies.

  • Supports content-based routing.

  • Maintains routing metrics and preferences.

  • Handles multicast and anycast delivery.

Message Buffer

The message buffer provides temporary storage by implementing the following:

  • Caches messages for reliable delivery.

  • Implements store-and-forward when needed.

  • Supports message deduplication.

  • Handles out-of-order delivery.

The diagram shows the message flow through the SLIM data plane components:

  1. Messages enter the system and are processed by the Message Buffer.

  2. The Message Buffer handles deduplication and store-and-forward.

  3. The Forwarding Table determines routing strategy.

  4. The Connection Table manages delivery to connected agents.

  5. Messages are delivered through direct, multicast, or anycast methods.
