"WebAbstract—Shortest path algorithms such as SPF and CSPF are widely used in online trafﬁc engineering where connections need to be setup one at a time as connection requests arrive sequentially. We propose an ap-proach, called design-based routing (DBR), whereby optimized paths com-puted ofﬂine are used to guide online path setups. " - Cspf algorithm
