Overview + +The **EventMesh A2A (Agent-to-Agent) Protocol** is a specialized, high-performance protocol plugin designed to enable asynchronous communication, collaboration, and task coordination between autonomous agents. + +With the release of v2.0, A2A adopts the **MCP (Model Context Protocol)** architecture, transforming EventMesh into a robust **Agent Collaboration Bus**. It bridges the gap between synchronous LLM-based tool calls (JSON-RPC 2.0) and asynchronous Event-Driven Architectures (EDA), enabling scalable, distributed, and decoupled agent systems. + +## 2. Core Philosophy + +The architecture adheres to the principles outlined in the broader agent community (e.g., A2A Project, FIPA-ACL, and CloudEvents): + +1. **JSON-RPC 2.0 as Lingua Franca**: Uses standard JSON-RPC for payload semantics, ensuring compatibility with modern LLM ecosystems (LangChain, AutoGen). +2. **Transport Agnostic**: Encapsulates all messages within **CloudEvents**, allowing transport over any EventMesh-supported protocol (HTTP, TCP, gRPC, Kafka). +3. **Async by Default**: Maps synchronous Request/Response patterns to asynchronous Event streams using correlation IDs. +4. **Native Pub/Sub Semantics**: Supports O(1) broadcast complexity, temporal decoupling (Late Join), and backpressure isolation, solving the scalability limits of traditional P2P webhook callbacks. + +### 2.1 Native Pub/Sub Semantics + +Traditional A2A implementations often rely on HTTP Webhooks (`POST /inbox`) for asynchronous callbacks. While functional, this **Point-to-Point (P2P)** model suffers from significant scaling issues: + +* **Insufficient Fan-Out**: A publisher must send $N$ requests to reach $N$ subscribers, leading to $O(N)$ complexity. +* **Temporal Coupling**: Consumers must be online at the exact moment of publication. +* **Backpressure Propagation**: A slow subscriber can block the publisher. + +**EventMesh A2A** solves this by introducing **Native Pub/Sub** capabilities: + +```mermaid +graph LR + Publisher[Publisher Agent] -->|1.

Functional Specification + +### 4.1 Message Processing Flow + +1. **Ingestion**: The adaptor receives a `ProtocolTransportObject` (byte array/string). +2. **Detection**: Checks for `jsonrpc: "2.0"`. +3. **Transformation (MCP Mode)**: + * **Request**: Parses `method`. + * If `message/sendStream`, sets type suffix to `.stream` and extracts `_seq`. + * If `_topic` present, sets `subject` (Pub/Sub). + * If `_agentId` present, sets `targetagent` (P2P). + * **Response**: Parses `result`/`error`. Sets `collaborationid` = `id`. +4. **Batch Processing**: Splits JSON Array into a `List`. + +### 4.2 Key Features + +#### A. Intelligent Routing Support +* **Mechanism**: Promotes `_agentId` or `_topic` from JSON body to CloudEvent attributes. +* **Benefit**: Enables EventMesh Router to perform content-based routing (CBR) efficiently. + +#### B. Batching +* **Benefit**: Significantly increases throughput for high-frequency interactions. + +#### C.

Overview + +The **EventMesh A2A (Agent-to-Agent) Protocol** is a specialized, high-performance protocol plugin designed to enable asynchronous communication, collaboration, and task coordination between autonomous agents. + +With the release of v2.0, A2A adopts the **MCP (Model Context Protocol)** architecture, transforming EventMesh into a robust **Agent Collaboration Bus**. It bridges the gap between synchronous LLM-based tool calls (JSON-RPC 2.0) and asynchronous Event-Driven Architectures (EDA), enabling scalable, distributed, and decoupled agent systems. + +## 2. Core Philosophy + +The architecture adheres to the principles outlined in the broader agent community (e.g., A2A Project, FIPA-ACL, and CloudEvents): + +1. **JSON-RPC 2.0 as Lingua Franca**: Uses standard JSON-RPC for payload semantics, ensuring compatibility with modern LLM ecosystems (LangChain, AutoGen). +2. **Transport Agnostic**: Encapsulates all messages within **CloudEvents**, allowing transport over any EventMesh-supported protocol (HTTP, TCP, gRPC, Kafka). +3. **Async by Default**: Maps synchronous Request/Response patterns to asynchronous Event streams using correlation IDs. +4. **Native Pub/Sub Semantics**: Supports O(1) broadcast complexity, temporal decoupling (Late Join), and backpressure isolation, solving the scalability limits of traditional P2P webhook callbacks. + +### 2.1 Native Pub/Sub Semantics + +Traditional A2A implementations often rely on HTTP Webhooks (`POST /inbox`) for asynchronous callbacks. While functional, this **Point-to-Point (P2P)** model suffers from significant scaling issues: + +* **Insufficient Fan-Out**: A publisher must send $N$ requests to reach $N$ subscribers, leading to $O(N)$ complexity. +* **Temporal Coupling**: Consumers must be online at the exact moment of publication. +* **Backpressure Propagation**: A slow subscriber can block the publisher. + +**EventMesh A2A** solves this by introducing **Native Pub/Sub** capabilities: + +```mermaid +flowchart LR + Publisher["Publisher Agent"] -->|1.

**Extension**: `a2amethod` | +| **Correlation** | `id` (e.g., `req-123`) | **Extension**: `collaborationid` (on Response)
**ID**: Preserved on Request | +| **Direction** | Implicit (Request vs Result) | **Extension**: `mcptype` (`request` or `response`) | +| **P2P Routing** | `params._agentId` | **Extension**: `targetagent` | +| **Pub/Sub Topic** | `params._topic` | **Subject**: The topic value (e.g. `market.btc`) | +| **Streaming Seq** | `params._seq` | **Extension**: `seq` | + +## 4. Functional Specification + +### 4.1 Message Processing Flow + +1. **Ingestion**: The adaptor receives a `ProtocolTransportObject` (byte array/string). +2. **Detection**: Checks for `jsonrpc: "2.0"`. +3. **Transformation (MCP Mode)**: + * **Request**: Parses `method`. + * If `message/sendStream`, sets type suffix to `.stream` and extracts `_seq`. + * If `_topic` present, sets `subject` (Pub/Sub). + * If `_agentId` present, sets `targetagent` (P2P). + * **Response**: Parses `result`/`error`. Sets `collaborationid` = `id`. +4. **Batch Processing**: Splits JSON Array into a `List`. + +### 4.2 Key Features + +#### A. Intelligent Routing Support +* **Mechanism**: Promotes `_agentId` or `_topic` from JSON body to CloudEvent attributes. +* **Benefit**: Enables EventMesh Router to perform content-based routing (CBR) efficiently. + +#### B. Batching +* **Benefit**: Significantly increases throughput for high-frequency interactions. + +#### C. Streaming Support +* **Operation**: `message/sendStream` +* **Mechanism**: Maps to `.stream` event type and preserves sequence order via `seq` extension attribute. + +## 5.
