Layer 4-7 Switches: Also known as content switches, these devices operate at the transport layer (Layer 4) and higher layers (up to Layer 7 – the application layer) of the OSI model. They not only manage network traffic based on IP addresses and port numbers but also on the basis of data content. This enables more complex and flexible network management, including load balancing and quality of service features, as well as advanced security features, such as protection against application-specific attacks.
