In this paper, we introduce an emergency optical network design problem for the low-cost post-disaster recovery of core optical transport networks. We take into account both the interconnection of the surviving multi-vendor resources and the utilization of portable emergency erbium-doped fiber amplifiers (EDFAs). The surviving multi-vendor optical nodes (e.g., reconfigurable optical add/drop multiplexer...
For the recovery of core optical transport networks after disaster, in this paper, we introduce an emergency optical network design problem. In this problem, we take account of both the interconnection of the surviving multi-vendor resources and the utilization of the emergency portable EDFAs. The surviving multi-vendor optical nodes [e.g., reconfigurable optical add/drop multiplexer (ROADM) or wavelength...
For the recovery of multi-layer networks after disaster, in this paper, we introduce two correlated planning problems which are based on the multi-vendor interconnection approach: 1) planning of emergency multi-layer network construction with the IP-over-Optical overlay model, and 2) planning of an operational process for control/management-plane (C&M-Plane) network recovery. We propose two corresponding...
