Here’s What’s Missing. **[Cisco](https://daily.dev/sources/cisco)** · 6 min read · 0 upvotes · 0 comments ## Summary A2A (Agent2Agent) is an emerging open standard that enables AI agents to communicate with each other, complementing MCP (which connects agents to tools). In the context of SD-WAN, individual edge agents making independent decisions can cause coordination failures — like a traffic stampede when all agents reroute simultaneously. A2A solves this by letting agents negotiate, share load, and collaborate. The post outlines a three-layer model: agents (decision-making), MCP (tool connectivity), and A2A (peer coordination). It also covers trust guardrails and a phased rollout path from centrally arbitrated communication to a fully autonomous agent fabric. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between MCP and A2A for AI agents? MCP lets an individual agent communicate with its tools and the systems it manages, acting like a universal interface or 'USB-C port for AI.' A2A (Agent2Agent) lets agents communicate with other agents, allowing them to identify themselves, share capabilities, and negotiate tasks. The two are complementary layers rather than competing technologies: MCP handles an agent's reach into the network, while A2A handles its coordination with peers. _Anyone architecting multi-agent network automation can follow how MCP and A2A protocols evolve on daily.dev._ ### Why can a network of individually smart AI agents still fail without coordination? Each agent may independently reach the same locally optimal decision, causing a collective failure like a stampede. In a retail SD-WAN example, when customer traffic spikes, every store's autonomous agent might reroute overflow to the same healthiest exit simultaneously, overwhelming that path instead of distributing load. Cooperation through a shared communication layer lets agents see one another and share the work instead of all pushing toward the same outcome. _Teams designing distributed agent systems can track patterns like this stampede problem on daily.dev._ ### What is the Agent2Agent (A2A) protocol for AI agents? Agent2Agent is an emerging open standard that lets AI agents communicate directly with other agents rather than just with their own tools. Its first stable release shipped, and it is now a Linux Foundation project. It enables agents to identify themselves, advertise capabilities, request that peer agents perform tasks, and receive completion notifications, replacing purely reactive agent behavior with negotiation. _Developers evaluating emerging agent coordination standards can follow A2A's progress on daily.dev._ ## Similar posts on daily.dev - [MCP and A2A: A Network Engineer’s Mental Model for Agentic AI](https://daily.dev/posts/mcp-and-a2a-a-network-engineer-s-mental-model-for-agentic-ai-l74fjxbsd) · Cisco · 1 upvotes · 0 comments - [Stop talking to AI, let them talk to each other: The A2A protocol](https://daily.dev/posts/stop-talking-to-ai-let-them-talk-to-each-other-the-a2a-protocol-xhgjvo7os) · The Next Web · 0 upvotes · 0 comments - [From Isolated Agents to Collective Intelligence: Why A2A Is the Protocol the Agentic SOC Has Been Waiting For](https://daily.dev/posts/from-isolated-agents-to-collective-intelligence-why-a2a-is-the-protocol-the-agentic-soc-has-been-wa-wm5fv6b4r) · Cisco · 0 upvotes · 0 comments --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#networking](https://daily.dev/tags/networking), [#mcp](https://daily.dev/tags/mcp) [View this post on daily.dev](https://daily.dev/posts/a-high-iq-network-isn-t-a-smart-network-here-s-what-s-missing--r4wl7zkxm) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"A High-IQ Network Isn’t a Smart Network.
