Impacts of GMPLS on topology design and protection planning of survivable IP-over-optical networks

The convergence of IP and optical networks through the GMPLS common control plane motivates a new paradigm of integrated network management. In this paper, we study how the new synergy between the IP and optical layers influence the decision on topology design and protection planning of survivable IP-over-optical networks. We discovered a new guideline which indicates that existing balanced and sparse networks could benefit the most from the migration from the single-layer management to the GMPLS-based multi-layer management.
