Novel method for fast IP network recovery

Routing is the process of selecting path in a network along which to send network traffic. Routing is performed for many kinds of network, including the telephone network, electronic data networks, and transportation networks. it involves two basic activities: Determining best path and forwarding packets through these paths. The internet routes packet one at a time, some of these packets may be delayed for various amounts of time or even lost in transmission. So a network must be designed to continue to operate when there are failures and service or maintenance interruptions in the network. Fast IP network recovery (FINR) is strictly connection oriented. FINR guarantee that packet reach by receiver. And it is base on additional route in each router. So FINR control Bandwidth, delay, load, reliability and Security. FINR is local mechanism and calculated backup in advanced when a failure is detected; the affected packets are immediately forwarded through backup path to shorten the service disruption. And recovery after failure is less than millisecond.
