Management of a plurality of sub-tunnels is disclosed herein. Resource utilization of a plurality of sub-tunnels of a network tunnel implementing a Resource Reservation Protocol is monitored. A resource utilization of a first set of the sub-tunnels exceeding a defined utilization threshold is detected. As a result of the detection, an adjusted resource utilization is determined for a second set of the sub-tunnels. The resource utilization of the second set of sub-tunnels may be less than a defined utilization threshold. The adjusted resource utilization is established for the second set of sub-tunnels for a next measurement interval. The adjusted resource utilization of each sub-tunnel of the second subset of sub-tunnels may be less than a lowest resource utilization among the first set of sub-tunnels.
