Past disasters, e.g., mega-quakes, tsunamis, have taught us that it is difficult to fully repair heavily damaged network systems in a short time. The only method for quickly restoring core communications is to start by fully utilizing the surviving network resources from different networks. However, as these networks might be built using different vendors' products (which are often incompatible with each other), the interconnection and utilization of these surviving resources are not straightforward. In this paper, we consider an all-optical multi-vendor interconnection method as an efficient reactive approach during disaster recovery. First, we introduce a disaster recovery scenario in which we use the multi-vendor interconnection approach. Second, we present two sub-problems and propose solutions: (1) network planning problem for multi-vendor interconnection-based emergency optical network construction and (2) interconnection problem for multi-vendor optical networks including both the data-plane and the control-and-management-plane. To enable the operation of multi-vendor systems, command translation middleware is developed for individual vendor-specific network control-and-management systems. Simulations are conducted to evaluate our proposal for sub-problem (1). The results reveal that multi-vendor interconnection can lead to minimum-cost network recovery. Additionally, an emergency optical network prototype is implemented on a two-vendor optical network test-bed to address sub-problem (2). Demonstrations of both the data-plane and the control-and-management-plane validate the feasibility of the multi-vendor interconnection approach in disaster recovery.
