GUARANTEED BANDWIDTH FOR SEGMENT ROUTED (SR) PATHS

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..sln...

Summary: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 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.
