Agentic AI: Rethinking the OSI Model for the Internet of Agents and Cognition
Agentic AI is changing how systems communicate. Explore why the OSI model may need Layer 8 and Layer 9 for identity, cognition, semantics, and meaning.
In the era of Agentic AI and the Internet of Cognition, the traditional OSI model designed for an Internet of Information may require reevaluation. As AI agents increasingly collaborate and exchange context, two proposed new layers by Cisco Research—Layer 8 and Layer 9—could enhance communication. Layer 8, the Agent Communication Layer, focuses on the structure and context of agent-to-agent conversations, while Layer 9, the Agent Semantic Layer, emphasizes meaning and intent.
These layers aim to go beyond mere data transfer and foster meaningful, efficient, and context-aware interactions. By incorporating these layers, agents could establish shared understanding, coordinate actions, and build a collective intelligence across distributed systems, moving closer to a cognitively connected "Cognition Fabric."
