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.

ngn use an ip as a transport unlike in analog switching, it uses packet switching
interconnecting several networks using different technologies.

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.
