Research overview
This survey examines task deployment and recovery across space, air, and ground networks using software-defined networking and network function virtualization.
The problem
Different network layers offer heterogeneous resources and support diverse services. Resource competition, changing connectivity, and failures complicate reliable task deployment.
The approach
The survey introduces the layered architecture and SDN/NFV mechanisms, then organizes service-function-chain deployment, intelligent scheduling, and matching-based recovery strategies.
Evaluation
A use case examines service-chain completion and recovery from resource failures. The original article provides the modeled deployment settings and the discussion of resource-management challenges.
