Cost Model Based Network Design March 29, 2018 Charleston, South Carolina DISTRIBUTION STATEMENT A: Approved for public release.

Acknowledgement The cost model was developed under the National Shipbuilding Research Program (NSRP) Panel Project Number 2016-426 “Paradigm for Optical Networks” www.nsrp.org

MOTIVATION FOR USE OF WDM LAN- Reduces weight, space, and complexity Reduces EMI susceptibility Flexible Infrastructure (FI) modular deployment Technology follows mature commercial applications Large capacity physical layer to accommodate all traffic

WHAT WE’VE LEARNED- WDM LAN ARCHITECTURES- Reduce number of physical connections Physical versus functional topologies Re-arrangeable backbone implementation MILITARY AND AEROSPACE- Highly variable traffic between static nodes The environment dictates allowable components Can use evolving data center technologies Constant increase in bandwidth demand

Access / Adaptation Elements change with application or mission BASIS FOR THE WDM LAN ISO / open systems view: Access / Adaptation Elements change with application or mission

BACKBONE NETWORK ELEMENTS PRACTICAL WDM LAN BACKBONE NETWORK ELEMENTS OTM- Optical Terminal Multiplexer OXC- Optical Cross Connect OPS- Optical Power Splitter OLA- Optical Line Amplifier OADM- Optical Add-Drop Multiplexer

COST MODEL DESIGN Follows WDM LAN architecture Open spreadsheet with instructions COSTS: Acquisition / Maintenance / Upgrade LABOR: Engineering / Install / Test / Maintenance / Upgrade TOTALS: All levels all categories switchable

COST MODEL

COST MODEL COMPARISON OF ALTERNATIVES From: Mazurowski, Habiby- AVFOP 2018

THIS PROJECT WILL- Task 1: Identify architectures, applications, and associated interface protocols and required adaptation (Ingalls Shipbuilding, Penn State ARL, and Vencore Labs). Task 2: Construct cost model for selected variants (Penn State ARL and Vencore Labs). Task 3: Develop simple WDM testbed using existing facilities (Vencore Labs and Penn State ARL). Task 4: Optimize interconnect methods considering single mode fiber and fusion splicing technologies (Ingalls Shipbuilding, Penn State ARL and Vencore Labs).

DELIVERABLES- Technical Report- includes task results, cost model results for specified architectures, and a template for network analysis. Quarterly Status Reports- three, six, and nine months. Panel Meeting Presentations- quantity two. Work Meetings- quantity two.

ISSUES- The project team will need platform specific information (Task 1); however the subcontractor assigned to this task did not subcontract. There may be an alternate vehicle that would be more suitable for participation of the original subcontractor. Ingalls Shipbuilding has prepared an estimate for the cost of taking on this task. The project would remain within its original budget.

NEXT STEPS- Kickoff teleconference. Solve platform information issue. Schedule work meeting.

Thank you!
