Multipath provisioning (MPP) uses multiple disjoint paths for data transmission to tolerate network failures. This paper proposes an MPP scheme, which allows allocating the different number of spectrum slots and different amount of transmission capacity to each path to minimize required spectrum resources in elastic optical networks. We present two optimization problems based on the proposed scheme and formulate them. Numerical results observe that the proposed scheme reduces the required spectrum resources compared to the conventional scheme, which allocates the same number of spectrum slots or the same amount of transmission capacity to each path.
