The Network layer (OSI Layer 3) is responsible for logical addressing and routing packets between end systems across different networks. IP, OSPF, and BGP operate at this layer. The Data Link layer handles node-to-node delivery on the same network segment. The Transport layer manages end-to-end communication between hosts. The Session layer manages sessions/connections between applications.
