Control Plane Architecture for User-centric
Dynamic Lightpath Provisioning

• User domain as associated partner in control
  plane
• ASON (Automatically Switched Optical Network) by
  ITU
• No sharing of user-owned resources.
• TeraGrid
• Clusters based domains, sharing of user-owned
  resources
• OptIPuter
• Clusters based domains, sharing of user-owned
  resources
• Diminishing optical core
• User domain as full partner in control plane
• CAnet4
• Fine granularity of shared optical resources
  (e.g., individual OXC port)
• User application as associated partner in
  control plane
• OMNInet (All-optical core, no sharing of
  user-owned resources)

OMNINet Application-centric Inter-domain
Intelligent Signaling

• Intra-domain Intelligent Signaling
• ODIN (Optical Dynamic Intelligent Signaling)
• TeraAPI, THOR, DEITI, GMPLS
• Inter-domain Intelligent Signaling
• PIN (Photonic Inter-domain Negotiator)
• PINAPI
• Generic API for both intra-domain and
  inter-domain
• PINGP (PIN Gateway Protocol)
• Supports domain-level source-routing to
  complement intelligent signaling.
• Future version will also extend BGP routing to
  support lightpath provisioning (i.e., PINGP will
  become a superset of OBGP).
• Inter-domain Security
• Advanced Scheduling
• GARA/Globus based scheduler

Management Plane Security Infrastructure

• GSI (Grid Security Infrastructure)
• Public key with X.509 certificates (like the web)
• Globus Security
• Each domain enforces its own security policy
  (Globus concentrates only on multi-domain
  security threats).
• Mechanism for cross-domain authentication, making
  a user known in remote domains.
• AAA (Authentication, Authorization, and
  Accounting)
• IETF defines intra-domain AAA
• IRTF defines inter-domain policy based AAA
