Packet layer

protection

Tunable interface &

ROADM protect +

› Coordinating protection layers is complex

– Upper layer protection must be aware of underlying protection scheme and speed

– But relax timing causes unnecessary delays should under-layer fail to protect

– Integration of dynamic signaling / coordination complex across multi-layer

› Packet level protection + Optical restoration offers ideal mix

– Packet layer provides rapid and flexible protection schemes

– Optical layer can work uncoordinated to provide restoration of the primary path

– Does require strict diversity of the optical path to guarantee success

› WHAT ABOUT PACKET-OPTICAL?

[…]

This could be the year packet-optical, specifically combined layer 0-2

equipment, re-enters the network debate in force, this time riding the

coat tails of SDN. Coupling P-OTS with a SDN allows the hardware

to essentially become less intelligent as the complex control

plane is decoupled from the optical hardware. In essence, this

lowers the barriers to entry for this technology, provided the operator is

moving to a more SDN-like control plane.
