The invention is a novel and efficient distributed control scheme for dynamic allocation and de-allocation of bandwidth. The scheme can be applied to MPLS or MPlambdS networks where bandwidth guaranteed connections (either protected against single link or node failure, unprotected or pre-emptable) need be established and released in a on-line fashion. It can be implemented as a part of the G-MPLS control framework. It achieves near optimal bandwidth sharing with only partial (aggregated) information, fast path determination and low processing and signaling overhead. Further, it can allocate and de-allocate bandwidth effectively as a request arrives, avoiding the need for complex optimization operations through e.g., network reconfiguration.
