| The objective of this thesis is to propose effective counter measures to address the problem of the malicious act of denial of Internet access by International Internet Service Providers (IISPs), and to increase the resilience of the Internet services. Furthermore, the thesis is to address this specific problem at the routing level. The proposed solution is dependent on the use of a tunneling protocol. The proposed solution and the effect of tunneling on the problem solution is evaluated through simulation experiments. For the simulation purpose the OPNET network simulator was used. The performance of the proposed solution is evaluated in terms of throughput, end-to-end delay, and packet drop. Both the proposed solution and the simulation experiments followed the Internet standards as closely as possible. |
