Ethernet
Packet Switching - Computer Communications (Digital)Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.

Receiving and making calls primarily involve two key technologies: circuit switching and packet switching. Circuit switching establishes a dedicated communication path between the caller and receiver for the duration of the call, commonly used in traditional landline systems. In contrast, packet switching breaks calls into smaller data packets that travel over a network, enabling more efficient use of bandwidth and supporting technologies like Voice over Internet Protocol (VoIP). Both methods rely on signaling protocols to manage call setup, control, and termination.
A MPLS network would be essential if you want to protect a network you may be using in two different locations. MPLS stands for Multi-Protocall Label Switching.
A circuit switching network physically changes the connection before it sends a message. This would be like the old pulse phone relay system. When you spun the dial on your phone for each number, there would be a switch that would physically move at the other end of the line. Each number switched you to a different set of switches which would in turn combine to make a physical route to your destination. A message switching network is what modern phone systems and computers use to communicate. Most computers use a "Store and Forward" type of switching. Once a network switch receives a message, it stores the entire message in memory, then sends it towards its destination. With message switching, there is no physical switching of the wires. All wires are connected to a processor which determines how to handle the message. For a good explanation of message switching and how packets work on the internet, watch the free movie "Warriors of the Net" from the website below. http://www.warriorsofthe.net/movie.html

What network does sprint use? I know Verizon uses cdma network
Although some would suggest that a switch could segment a network (and it does use the MAC address for switching) more properly a bridge would be the answer if you are speaking of segmenting a network.
It is simplest form of switching which have dedicated physical path between sending and receiving. In circuit switching network,a set of switches are connected by physical link. A connection between the two stations is a dedicated path made up of one or more links.
