Abstract Software-Defined Networking (SDN) has been proposed as a promising way for its
centralized network control and management. However, the latest SDN research focuses on …

The space–air–ground integrated network (SAGIN) is considered to be a significant
framework for realizing the vision of “6G intelligent connection of all things.” A typical SAGIN …

As the large-scale application of software-defined networking (SDN), one major research
challenge for the SDN is to place multi-controllers reasonably. The researchers have …

By separating control plane from data plane, software‐defined network (SDN) adopts
centralized controllers to manage data flows in the network. Nevertheless, the rapid growth …

Satellite networks can help extend wider communication coverage and provide more types
of services; and introducing service function chain (SFC) to satellite networks can enhance …

Software Defined Networking (SDN) marks a paradigm shift towards an externalized and
logically centralized network control plane. A particularly important task in SDN architectures …

Software-Defined Networking (SDN) is a developing architecture that provides scalability,
