• Design Principles– User-Group based Virtual Network Control/Use

• Root users *control*, General users *use*

– Easy-to-Use User Interface• Simple and Rapid: several-click Easy, ms Fast

– User-oriented Network Visualization and Monitoring

• Virtual Network Topology and Operational Attributes

ONOS Build 2016 12

ONOS Build 2016 13

• Pruning strategy– Link(s) should support required BW while 

not being allocated by other VDNs

• Unification of multiple links– Select links with minimum BW

• Spanning tree algorithm– Find center node which has the 

minimum number of hop counts between center and access switches

– Find shortest paths between center and access switches

– Merge the shortest paths = Spanning tree = VDN

ONOS Build 2016 14

ONOS Build 2016 15

• Detection of removed‐link events– Discover VDNs with removed link(s)– Update VDN based on corresponding input 

information (Required BW, VDN end‐hosts)

Global Network

Origin VDN Updated VDN

ONOS Build 2016 16

• CLI for VDN– vdn-create [bandwidth: Mbps] [host id list]– vdn-update [vdn id/name] [bandwidth(Mbps)] [host id list]– vdn-remove [vdn id/name]– vdn-list– vdn-detail [vdn id/name]
