Distributed Denial-of-Service (DDoS) attacks can collapse even the well-structured networks. Now-a-days with evermore-powerful tools in a hacker's armoury, DDoS attacks are easier to launch. Typical types of DDoS attacks include bandwidth attacks and application attacks. In a bandwidth attack, network resources or equipment are exhausted by a bulk volume of packets. In application attack, TCP or HTTP resources are prevented from processing transactions. The authors concentrated in bandwidth attacks by using network coding concept along with the alternate path selection by using IP trace back one hop concept. Router acts as a intermediate to transfer packets across networks.
