Single Domain Controller NBI Requirement Network resource retrieval Retrieval of Node, Ltp and Link Including ETH, ODU, Och Info Statistics of network resource utilization (For which I think we are running out of time) Gap: Protection characteristic of Link, e.g. a ETH Link is supported by a ODUk Connection, the Protection characteristic of this Link will inherit the Protection Type of this Connection. Path Computation Support following Objective Function: Minimum Hop, Minimum Link Cost, Minimum Latency, Load Balance Support following Topology Constraint: Include/exclude Node or Link, Optical Layer Constraint(Constraint of Wavelength and Optical Layer Performance, Considering OSNR, CD, PMD), Combination of above constraints Diversity Policy for resilience (SRLG, Link/Node diversity) Gap: Minimum Hop, Minimum Latency, Load Balance, Optical Layer Constraint Connection Management Creation and Deletion of 10GE, STM-N, OTUk, EPL/EVPL/EP-LAN/EVP-LAN and Och Traffic Modify Connection with: Capacity, Resilience Constraint Support following Resilience Constraint: 1+1 Permanent Protection, 1+1 Protection Combine with Dynamic Restoration, Pre-compute Route Restoration, Dynamic Restoration Gap: Resilience Constraint, Distinguish of virtual traffic (i.e. between EPL and EVPL, or between EPLAN and EVPLAN)

Multi-Domain Inter-operate Requirement Network resource retrieval Configuration of Inter-Domain Links (Auto-discovery is Optional) The rest Same as Single-Domain. Gap: Configuration of Inter-Domain Links Path Computation Topology Constraint for Inter-Domain Links Connection Management Resilience Constraint divided into two parts: Per-Domain(Segment) Resilience Constraint and End2End Resilience Per-Domain(Segment) Resilience Constraint: Same as Single-Domain requirements End2End Resilience: End to End ODUk 1+1 Protection, End to End Dynamic Restoration

Protection characteristic of Link protectionType -> resilienceType, also the data type

Route Compute Policy proposed to add OpticalRoutingStrategy to OTSi Module and augment the RouteComputePolicy Pac ; Relay to Regenerate?( to make sure )

Distinguish of virtual traffic add description and examples of the isExclusieveService

Resilience Requirements

single-domain - 1+1 Permanent Protection Once Route failed, restore this route

single-domain - 1+1 Protection Combine with Dynamic Restoration Both Routes failed, then restore this service

single-domain - Pre-compute Route Restoration Compute one Path for a Connectivity-Service but not reserve resources, when C-S failed, restore with this Path

single-domain - Dynamic Restoration when C-S failed, compute a new route and restore

Per-Domain(Segment) Resilience Constraint Same as Single-Domain requirements

End2End Resilience: End to End ODUk 1+1 Protection, End to End Dynamic Restoration

Resilience Constraint
