1. Intelligent Signaling Objectives
• Application-centric Signaling
– Enable applications to control and provision lambda-switched paths or lightpaths
within an all-optical network.
• Centralized Control Plane
– Intra-Domain GMPLS (Generalized Multi-Protocol Label Switching)
– Inter-Domain OBGP (Optical Border Gateway Protocol)
– O-UNI (Optical User Network Interface)
• Collaborative optical networking:
– Dynamic provisioning of lightpaths.
– On-demand rerouting of lightpaths.

 Inter-domain Intelligent Signaling
 LightGate (optical signaling gateway) Mechanism
•
1st Phase: Inter-Working Function between OMNInet and NetherLight.
•
2nd Phase: Generic scalable signaling gateway between any two domains
–
.
A superset of OBGP (Optical Border Gateway Protocol) to extend BGP
routing to support lightpath setup & management.
–
Support domain-level source-routing to complement intelligent signaling.

2. Flexible Lambda Provisioning Objectives
• Framework to support e-science (optional e-commerce) applications
with a diverse range of throughput and traffic requirements.
• Current Features
– Single-Lambda Applications (Gb applications)
•
Lambda-switched path or lightpath
– Multiple Applications per Lambda (Kb/Mb applications)
• DEITI (Dynamic Ethernet Intelligent Transit Interface) to
encapsulate logical label-switched paths within a lightpath.
• Future Implementations
– Multi-Lambda Applications (Tb applications)
• Optical inverse-multiplexing scheme.
– Bursty Applications
• DASOBS (Dynamic Adaptive Slotted Optical Burst
Switching) to support bursty and variable-rate traffic
requirements.

3. User-Empowered Ad-hoc Sharing Objectives
•
User-Empowered Ad-hoc Sharing
–
–
•
Distributed Control Plane over Lightpath Objects
–
–
•
Users own, control and manage lightpath objects (fibers, lambdas, optical
cross-connects, etc.).
Enable users or organizations to advertise portions or all of their lightpath
objects to other users when not in use.
Enables rapid sharing and provisioning of lightpath objects across multiple
independent management domains.
Enable dynamic configuration of optical-VPN.
Object Oriented Networking Architecture
–
–
Object Model: defines how lightpath objects are distributed across a
heterogeneous environment.
Reference Model: defines interactions among lightpath objects.
