In terms of IP network design, faults cannot be restored within less than one second. However, applications such as VoIP are increasingly demanding for rapid Fault Detection and recovery. A new protocol called Bidirectional Forwarding Detection (BFD) will help solve this problem and improve fault detection and recovery speed. As a draft IETF standard, BFD provides a simple method for detecting the forwarding
