The basic data in layer 3 is packets. The packets are made of fields such as TTL, source address, destination address, payload etc. Router and Layer 3 switches are examples of Layer 3 devices.What is the purpose of a layer 3 switch? Purpose of Layer 3 Switches. Layer 3 switches were conceived as a technology to improve network routing performance on large local area networks (LANs) like corporate intranets. The key difference between Layer 3 switches and routers lies in the hardware internals.
