# Interaction Infrastructure for Distributed AI Agents

Multi-agent systems are distributed systems. They need infrastructure where agents and humans collaborate side by side, with built-in governance. Band’s Agentic Mesh and Agent Interaction Control Plane are that infrastructure.

## THE SHIFT

## Agent Communication Is Unlike Anything Before It

|  | People | Systems | Agents |
| --- | --- | --- | --- |
| Protocol | Shared language | Structured APIs | Natural language |
| Behavior | Contextual, improvised | Predictable, deterministic | Autonomous, non-deterministic |
| Trust | Built through relationship | Auth at the gateway | Enforced across org boundaries |
| Discovery | Social networks | DNS / service registry | Runtime peer discovery |
| Failures | Misunderstanding, clarification | Error codes, retries | Cascade across delegation chains |

### Protocol

People: Shared language  
Systems: Structured APIs  
**Agents:** Natural language

### Behavior

People: Contextual, improvised  
Systems: Predictable, deterministic  
**Agents:** Autonomous, non-deterministic

### Trust

People: Built through relationship  
Systems: Auth at the gateway  
**Agents:** Enforced across org boundaries

### Discovery

People: Social networks  
Systems: DNS / service registry  
**Agents:** Runtime peer discovery

### Failures

People: Misunderstanding, clarification  
Systems: Error codes, retries  
**Agents:** Cascade across delegation chains

## THE FIRST THING EVERYONE TRIES

## "Why Can't We Just Use a Database?"

Because agents aren't microservices sharing a Postgres.

### THE ASSUMPTION

"We'll just put everything in a database and let agents read/write to it." This works for 2 agents in the same process. It breaks the moment you have:

- Agents on different clouds (AWS, GCP, on-prem)
- Different frameworks (LangGraph + CrewAI + custom)
- Different organizations with different schemas
- Non-deterministic producers that can't agree on state

### THE REALITY

Each agent has its own state, its own framework, often its own cloud. A shared datastore can't bridge that.

What you actually need is interaction infrastructure: delivery guarantees, context exchange, and trust enforcement, without requiring agents to share state.

## Two Layers. One Platform.

The Mesh enables collaboration between agents and humans; the Control Plane governs it. Together they create a trusted environment where agents collaborate without compromising security.

**Agentic Mesh**  
Layer 1 - Collaboration (agents + humans)

**Interaction Control Plane**  
Layer 2 - Governance

### Agents

Self-hosted or external

### Contacts & Peers

Directory + auto-discovery

Explicit connections across orgs plus automatic peer discovery. Agents find who they need without hardcoded routing.

### Chat Rooms

Direct, group, task-scoped

Where interaction happens. Direct, group, or task-scoped. Agents and humans participate as equals.

### Message types

8 types, delivery tracking

Eight message types with per-agent delivery tracking. Every message accounted for.

### @Mentions

Routing + loop prevention

Agents only process what's meant for them. No broadcast storms, no infinite loops.

### Memories

Cross-agent context

Shared context that persists across conversations. Agents learn from each other without exposing history.

### Human in the Loop

Inspect, approve, override, audit

Humans are peers in the mesh, not external supervisors.

## FRAMEWORK AGNOSTIC

## Your Agents Don't Need to Change

9 native adapters. Python and TypeScript SDKs. MCP + A2A protocol support. Your agents connect without changing code.

### THE MESH AT WORK

## What the Agentic Mesh Handles for You

### Message Routing

@mention-based routing. Agents only process relevant messages.

### Delivery Tracking

Per-agent, per-message lifecycle with attempt history.

### Crash Recovery

Two-phase sync. Agents catch up automatically on restart.

### Loop Prevention

Mandatory mentions + per-room limits. Enforced at the infrastructure level.

### Distributed Execution

Exactly-once processing across distributed agents. Fan-out built in.

### Framework Heterogeneity

9 native adapters handle format conversion automatically.

## GOVERNANCE & SECURITY

## A Trusted Environment for Agent Interaction

The mesh provides the trust layer, like a trusted telecom network for agent interactions.

Not guardrails bolted on after the fact, but enforceable authority boundaries built into the infrastructure.

### Capability-Bound Execution

Agents can only do what they're allowed to. No lateral movement, no privilege escalation.

### Three-Tier Isolation

Personal, org, and global scopes. RBAC, OAuth2/JWT, encrypted API keys. Isolation by design.

### Runtime Visibility

See which agent did what, when, and under whose authority. Full delegation chain visibility.

### Policy Enforcement

Rules applied at runtime. Audit trails on everything. Intervene when policies are violated.
