Enablers for IoT & 5G Innovation and Services

• Innovative IoT services such as Tactile Internet, Autonomous Driving and Massive M2M are considered major service offers in the future.

• These IoT services are characterized by very diverse QoS, security, latency and mobility requirements.

• Consequently, a more flexible, adaptable network than the existing 4G is required to accommodate and inspire IoT service innovation.

• For each service innovation, a specific network with the designated QoS, security, latency and mobility features must be provided.

• Network slicing envisaged by 5G networks will be the answer.

• SDN/NFV are the key technologies to realize network slicing in 5G.


What’s Network Slicing? Three Example Network Slices defined by NGMN

What are SDN and NFV?

• SDN (Software-Defined Network) separates the control plan from the data plan via an SDN controller by defining a northbound and a southbound API.

• NFV (Network Function Virtualization) transforms traditional hardware-based network appliances to software-based service applications or APPs.

• SDN and NFV complement each other and jointly enable slicing-required network softwarization and virtualization.

NCTU Project on “SDN-enabled Cloud-based Network Technologies & Services” 2015-2017• Technical Focuses

• Controller• SDN Multi-Controller• Service Chaining• Network Virtualization• Service Orchestration• Southbound APIs• Northbound APIs• SDN Switch/Access Point


NCTU Research Accomplishments on “SDN-enabled Cloud-based Networks”• Established the NCTU SDN testbed that incorporates Ryu、OpenDaylight and

ONOS controllers with a variety of SDN switches from different vendors.

• Successfully participated in global SDN-IP Peering of ONF and connected the NCTU SDN testbed to eight cities around the globe in five continents to increase the visibility of Taiwan.

• Successfully assisted Chunghwa Telecom to incorporate SDN in their broadband networks based on Ryu as the controller.

• Proactively promoted an SDN ecosystem in Taiwan.

• Trained over 250 PhD/MS students in the MOST project with expertise in SDN/NFV

• Produced more than 35 patents

• NCTU Network Benchmarking Lab (NBL) was approval by ONF as one of seven ONF Authorized Test Labs for OpenFlow conformance testing.
