Abstract To construct Reconfigurable Service Carrying Network (RSCN) in Reconfigurable Flexible Network (ReFlexNet) infrastructure can effectively solve the puzzle faced by traditional internet infrastructure. Resilient construction problems of RSCN in the precondition of physical link prone to failure are discussed. Mathematics model of RSCN resilient construction issues are established. To avoid enormous influence because of important resource failure, a Resource Stress Factor (RSF) Awareness RSCN Construction Algorithm named RSF-ACA is proposed. To improve success running ratio of RSCN, RSCN Link Failure Recovery Algorithm named RSLFRA is implemented when single link failure takes place. The efficiency of algorithms is evaluated by emulation experiments according to RSCN success running ratio and different RSF resource distribution and physical link utilization under several scenarios.
