Hierarchical PCE architecture is considered in multi-domain EONs. A novel scheme is proposed to proactively update the parent PCE using BGP-LS. Simulations show that the proposed scheme reduces blocking probability and parent PCE control load.

Abstract
Hierarchical PCE architecture is considered in multi-domain EONs. A novel scheme is proposed to proactively update the parent PCE using BGP-LS. Simulations show that the proposed scheme reduces blocking probability and parent PCE control load.File in questo prodotto:
