Network virtualization/softwarization

Network virtualization/softwarization has been introduced as a key role in the next-generation networking paradigm to fend off the ossification of traditional networks. While network virtualization/softwarization leads to a more flexible network by adopting the technologies of computer virtualization, network function virtualization (NFV), and software-defined networking (SDN), it brings challenges for network management, one of which is how to efficiently allocate network resources considering different requirements such as reliability and latency. We study resource allocation for different problems with typical application scenarios in network virtualization/softwarization.

Optical networks

Data traffic has tremendously increased with the grouth of network applications. Different optical networking technologies has been introduced to make the transmission capacity closely follow this exponential growth. We study various aspects of these emergeing technologies, especially elastic optical networks (EON) and space division multiplexing (SDM) networks, to relileze extremely high capacity networks.
