What are the protocols used in circuit switching and packet switching network?

In circuit switching, the primary protocols used are Signaling System 7 (SS7) and the Resource Reservation Protocol (RSVP), which facilitate the establishment and maintenance of a dedicated communication path. In contrast, packet switching relies on protocols like internet Protocol (IP) and Transmission Control Protocol (TCP), which allow data to be broken into packets that can travel independently across the network and be reassembled at their destination. Both methods serve different networking needs, with circuit switching focusing on consistent connections and packet switching prioritizing efficient data transmission.
