Super PTN Feasibility

Whole network transfer：High risk with not well-proven benefit

Start from Small PTN：risk under control, good technology available, predictable Apps innovation Controller which is similar to NMS MPLS-TP traffic encap/decap already supported by OpenFlow QoS：basic Shaping and Policing support by OpenFlow Meter

Function OAM ：extendable by OF-Config Protection：extendable by OpenFlow Group functionality

Small PTN to Small Super PTN- Maybe we could do better

Unified hardware platform for both Small PTN and Small Super PTN

Lower power and cost

Large flow table for more innovation

Better hardware based OAM and protection

Summary

Small PTN is a good point for Super PTN. Available technology with possible Apps innovation

Super PTN needs extension of current OpenFlow and OF-Config，such as OAM and APS

Much voice for SDN on small PTN/NID
