This letter presents a generic adaptive multipath routing solution. The method, called
Core-State-Limited Load Sharing (CSLLS), has two parameters. One determines the adaptation
time to load changes and the other one controls how long the path of a flow is unchanged.
With these two parameters CSLLS is capable of modelling previous multipath routing
concepts like ECMP, OMP and QoSPF. CSLLS overcomes the limitations of earlier approaches
by being adaptive (opposed to ECMP), by ensuring path integrity for a flow (opposed
to OMP), and by relying on only a few stored states in core routers (opposed to QoSPF).
