Near loop-free routing
Klaus M. Schneider, Beichuan Zhang, Lan Wang, Lixia Zhang · 2017
When splitting traffic for one destination among multiple paths, the employed paths should be loop-free, lest they waste network resources, and the involved routers should be given a high path choice, that is, a high number of potential nexthops. In IP networks this requires the use of a loop-free routing protocol, which limits the achievable path choice.
