・Multi-layer topology in one viewFeatures in Demonstration
・Support multiple protocols(NETCONF, TL1, REST, OpenFlow...)
・Hierarchical path management and protection switching
Normal View Oblique View
Available paths Primary path and Backup path
OpenFlow, SNMP, TL1, NETCONF, REST
OPS: Optical Protection Switch
Demonstrated on ONS 2017 by ON.Lab
・Open source project・Governed by ON.Lab・NTT Communications acts as a partner
