The explosive growth of mobile internet and bandwidth-intensive applications is creating a huge demand for bandwidth. The backbone networks spanning large areas are subject to various failures, such as natural disasters, operation errors, and malicious attacks. A robust network provisioning scheme that can survive failures is desirable to avoid data and revenue loss. Multipath provisioning can significantly outperform conventional single-path provisioning in resource efficiency, service resilience, and flexibility. This book investigates the algorithm design for multipath provisioning considering the differential-delay constraints. This book has proposed novel adaptive methods for disaster failure protection and recovery. The algorithm presented in this book has practical usage significances for modern data center service provisioning. It also provides a good guidance for multipath provisioning research.
