Integrating A2A Protocol - Intelligent Agent Communication Solution for BeeAI Framework
Using A2A protocol instead of ACP is a better choice for BeeAI, reducing protocol fragmentation and improving ecosystem integration.
A2A vs ACP Protocol Comparison Analysis Report
A2A (Agent2Agent Protocol) and ACP (Agent Communication Protocol) represent two mainstream technical approaches in AI multi-agent system communication: 'cross-platform interoperability' and 'local/edge autonomy' respectively. A2A, with its powerful cross-vendor interconnection capabilities and rich task collaboration mechanisms, has become the preferred choice for cloud-based and distributed multi-agent scenarios; while ACP, with its low-latency, local-first, cloud-independent characteristics, is suitable for privacy-sensitive, bandwidth-constrained, or edge computing environments. Both protocols have their own focus in protocol design, ecosystem construction, and standardization governance, and are expected to further converge in openness in the future. Developers are advised to choose the most suitable protocol stack based on actual business needs.
Building an A2A Currency Agent with LangGraph
This guide provides a detailed explanation of how to build an A2A-compliant agent using LangGraph and the Google Gemini model. We'll walk through the Currency Agent example from the A2A Python SDK, explaining each component, the flow of data, and how the A2A protocol facilitates agent interactions.
