Abstract
At least one bandwidth-guaranteed segment routing (SR) path through a network is determined by: (a) receiving, as input, a bandwidth demand value; (b) obtaining network information; (c) determining a constrained shortest multipath (CSGi); (d) determining a set of SR segment-list(s) (Si=[sl1i, sl2i . . . slni]) a that are needed to steer traffic over CSGi; and (e) tuning the loadshares in Li, using Si and the per segment-list loadshare (Li=[l1i, l2i . . . lni]), the per segment equal cost multipath (“ECMP”), and the per link residual capacity, such that the bandwidth capacity that can be carried over CSGi is maximized.
