Interdomain Traffic Engineering Techniques to Overcome Undesirable Connectivity Incidents
The importance of Internet availability is supported by the overwhelming dependence of government services and financial institutions upon said availability. Unfortunately, the Internet is facing different level of undesirable connectivity incidents. So, it is imperative to take serious measures in order to increase Internet connectivity resilience. We consider a scenario where a concerned region is facing an undesirable connectivity incident by its primary Internet Service Provider (ISP) which still advertises reachability to the concerned region. Assuming that connectivity to a secondary ISP is available, software is designed to implement different traffic engineering techniques in order to enhance internet connectivity resilience and send the traffic through the secondary ISP. The work is characterized by the implementation of these traffic engineering techniques in the laboratory through a detailed set of experiments.
