Overview:
In Multi-Protocol Label Switching (MPLS) networks, traffic demands can be routed along tunnels called Label Switched Paths (LSPs). One tunnel is characterized by a path in the network and a reserved bandwidth. These tunnels can be created and deleted dynamically, depending on traffic demand arrivals or departures. After several operations of this type, the network resources utilization can be unsatisfactory, with for instance congestion or too long routing paths. One way to improve it is to reroute tunnels. Different rerouting procedures may be applied, breaking tunnels or using make-before-break.
