SONET, ISDN, Frame Relay, ATM—all of these are wide area protocol examples that are traditionally associated
with leased circuits, which can include ISDN BRI/PRI; DS-x - T1, T2, and T3; or Optical Carrier circuits (OC). These concepts are explored briefly in the NIST SP800-34 Section 5, but you can easily find more information on the Web. In a disaster recovery situation, assess the benefit of a leased circuit over an open or virtual circuit.
Some organizations are forgoing the expense of a private leased WAN in favor of a public vWAN. Compare advantages of public vWAN over private leased WAN, and assess the impact on contingency planning.
