The IP-switching function is meant to create more stability on the Web by allowing an overloaded Web site to switch servers without a hiccup.

FORBES: Future Phishing

Their conclusion is that the switching and transmission costs for IP-based telephone networks are much lower than for switched circuit telephone networks.

CNN: IP telephony is the "in" thing these days, but should it be?

They then analyze how the remaining major cost components, switching and transmission for both types of networks and interconnecting with the switched circuit network for the IP-based networks, change with the change in technology.
