Claim 6:
7. A non-transitory computer-readable storage medium having a computer-readable code stored thereon, the computer-readable code that when executed by a processor of a label edge router (LER), causes the LER to perform steps of:
receiving link utilization measurements flooded by one or more Label Switch Routers (LSRs)
wherein the link utilization measurements are for links associated with one or more SR tunnels; determining whether the one or more SR tunnels are congested, based on one or more of an unreserved bandwidth, a maximum reservable bandwidth, and a maximum bandwidth of corresponding links, where a given SR tunnel is determined to be congested based on one or more of (1) a negative value of the unreserved bandwidth, (2) the maximum reservable bandwidth being greater than the maximum bandwidth, and (3) the maximum reservable bandwidth being equal to the maximum bandwidth; and
causing performance of one or more routing actions for the one or more SR tunnels based on the determination.
