Packet Optical Networking
Routers and Transport
Management plane integration
Transport NM displays, monitors and
manages native router DWDM ports
and services
Transport NM can partition DWDM
network bandwidth “reservation
rules” per customer requirements
Data plane integration
OTN and non-OTN DWDM router
ports connected directly to DWDM
platform without the need for
transponders
More than 1000km transmission
distance demonstrated at 10Gb/s
Control plane integration
MPLS/GMPLS interop enables router user (via CLI) or automated
script to create end to end loose paths across the transport network
without needing to manually configure the DWDM equipment

Why “Packet Optical” Networking?
Service Velocity Leading to New Service Creation
Introduction of new service features / pricing
Enabling customers to control their Bandwidth requirements
Service Flexibility Leading to CAPEX & OPEX savings
Efficient use of network resources
Minimize equipment requirements
• Transponder elimination and router bypass
Service Reliability Leading to Improved Customer Satisfaction
Eliminating the human aspect of bandwidth provisioning
Improved multi-layer protection/restoration co-ordination

Dynamic Provisioning Example
Automated BW Provisioning
•Initial path set-up
•JUNOS CLI based
connectivity request
•Additional traffic
request leading to IP
congestion
•Automated additional
path setup, balancing
traffic, reducing
congestion
