  • Much attention is on emerging technology, yet carriers must deliver services over diverse networks based on legacy, contemporary and cutting edge technologies.
  • There is no universal convergence layer or technology that meets everyone’s requirements

ASON Architecture and OIF IAs
  • ASON architecture addresses the transport network evolution
    • Heterogeneous network topologies, technologies, and applications
    • Diverse internal control plane protocols, including management-based
    • Separation of transport and control planes
  • OIF complements the work of optical standards bodies
    • Implementation Agreements (IAs) based on standards
    • Interoperability testing and prototyping of solutions

OIF Multi-layer Control Plane ModelGeneric Technology Layers with Recursion
  • Edge nodes typically provide layer adaptation and multi-layer control plane. Core nodes typically operate in single server layer
  • Supports non-disruptive modification (BW or VLAN IDs) to meet varied demands of client while in-service
  • Versatile – supports only layers needed (e.g Eth-VCAT-SDH, packet over WDM) yet supports multiple layer adaptations
    • Server layer call/connection signaling flow completes before client layer
