Agent Gateway Features

Core capabilities for agent communication.

🆔

Agent Identity

Manage unique agent identities with cryptographic authentication. Verify agent credentials and maintain identity across sessions.

🔐

Access Control

Define which agents can communicate with each other. Enforce role-based permissions and capability restrictions.

📨

Message Routing

Route messages between agents based on destination, capability, or load. Support point-to-point and broadcast patterns.

💾

State Synchronization

Share state across agents in real-time. Maintain consistent view of shared memory and conversation context.

Load Balancing

Distribute requests across multiple agent instances. Scale agents horizontally based on demand.

📊

Observability

Track agent interactions, message flows, and performance metrics. Debug complex multi-agent conversations.

Communication Protocols

Standard protocols for agent interaction.

📡

Request-Response

Synchronous communication pattern where one agent requests and another responds.

agent_a → gateway: REQUEST
gateway → agent_b: FORWARD
agent_b → gateway: RESPONSE
gateway → agent_a: DELIVER
📢

Pub/Sub Messaging

Asynchronous broadcasting to multiple subscribed agents.

agent_a → gateway: PUBLISH topic
gateway → agent_b: NOTIFY
gateway → agent_c: NOTIFY
gateway → agent_d: NOTIFY
🔄

Streaming

Continuous message stream between agents for real-time data transfer.

agent_a → gateway: STREAM OPEN
agent_a → gateway: CHUNK 1
agent_a → gateway: CHUNK 2
agent_a → gateway: STREAM CLOSE
🤝

Handshake

Negotiation protocol for establishing agent communication channels.

agent_a → gateway: HELLO + CAPS
gateway → agent_b: INTRODUCE
agent_b → gateway: ACCEPT
gateway → agent_a: CONNECTED
