An important aspect in designing a multiprotocol label switching (MPLS) network is to determine an initial to-
pology and to adapt it to the traffic load. A topology change in an MPLS network occurs when a new label switched
path (LSP) is created between two nodes. The LSP creation involves determining the route of the LSP and the ac-
cording resource allocation to the path. A fully connected MPLS network can be used to minimize the signaling. The
objective of this paper is to determine when an LSP should be created and how often it should be re-dimensioned. An
optimal policy to determine and adapt the MPLS network topology based on the traffic load is presented. The problem
