On April 10, Google announced the launch of an intelligent agent interaction protocol called Agent2Agent (A2A for short). The core value of this protocol is to provide an open and standardized technical framework for collaboration between AI agents.

The launch of this agreement marks an important step forward in cross-platform collaboration and ecosystem integration of AI technology, which will undoubtedly significantly improve productivity and reduce long-term costs.

The core concept of A2A protocol


The core of the A2A protocol is to achieve interoperability between AI agents. No matter what underlying technology these agents are developed with, through this protocol, AI agents from different suppliers can collaborate seamlessly and complete complex tasks together.

Google also revealed that A2A is not intended to replace existing AI technology, but rather to serve as a supplement and work in conjunction with other technical frameworks such as the MCP (Model Context Protocol) proposed by Anthropic.

The goal of the A2A protocol is to give intelligent agents greater autonomy while improving efficiency through collaboration. For example, in an enterprise environment, multiple intelligent agents can work together to complete full-process tasks from data analysis to customer support without the need for human intervention, which greatly reduces labor costs and improves work efficiency.


Technical basis and functional characteristics


The A2A protocol is built on existing popular technical standards, including HTTP, SSE (Server Sent Events), and JSON-RPC, etc. The maturity and widespread adoption of these technologies provide a stable technical foundation for A2A.

A notable feature of A2A is that it supports long-duration tasks and can process multiple data formats such as audio and video. This means that agents can work together in complex scenarios, for example, processing multimedia content in real time or performing multi-step tasks.

In terms of specific implementation, A2A adopts a client-remote agent collaboration model, in which the client agent is responsible for formulating tasks and conveying instructions, while the remote agent focuses on the execution of specific tasks. Both parties transmit information through standardized interfaces to ensure the efficiency and consistency of collaboration.


A brief discussion on A2A application scenarios


The application scenarios of the A2A protocol are quite extensive. In an enterprise environment, it can be used to optimize supply chain management, automate customer service processes, and even support complex decision support systems.

At the individual user level, A2A can help users integrate AI services from different suppliers, such as smart home devices, personal assistants, and content generation tools, to achieve a smarter and more personalized experience.

In addition, the openness of A2A also provides developers with a lot of room to play. Developers can build new intelligent entities based on this protocol, allowing it to be seamlessly integrated with the existing AI ecosystem. This openness not only promotes technological diversity, but also lays the foundation for the establishment of industry standards.


Partners and Industry Impact


Google's A2A protocol has received support from more than 50 technology partners, which shows the industry's recognition of this protocol. These partners include technology companies, research institutions and industry leaders. Their participation will definitely further promote the popularization and application of A2A.

Summarize


Google's Agent2Agent protocol represents a new direction in the development of AI technology. By achieving seamless collaboration between intelligent agents, A2A not only improves productivity, but also paves the way for the widespread application of AI technology.

With the participation of more partners and the expansion of application scenarios, A2A is expected to become an important foundation of the future AI ecosystem, promoting technological progress and industry innovation.
