TCP/ IP is named after its two primary protocols. However, when TCP/ IP is compared to OSI, we can say that the TCP/ IP protocol suite is made of five layers: physical, data link, network, transport, and application. The original TCP/ IP protocol suite was defined as having four layers: host-to-network, internet, transport, and application. Forouzan” Data communications and Networking 28  The layers in the TCP/ IP protocol suite do not exactly match those in the OSI model. No 517) What is Frame Relay? High-performance WAN protocol Operates at the physical and data link layers Originally designed/BRI)(Applicable for home users) Primary rate interface (PRI)(Applicable for corporate customers.)

Switching at Physical Layer At the physical layer, we can have only circuit switching. Packet switching can further be divided into two subcategories-virtual circuit approach and datagram approach Switching and TCP/ IP Layers Switching can happen at several layers of the TCP/ IP protocol suite.
