Making 100G/200G Economical for DCI

Nice, June 29, 2016

Revolution in content delivery model drives

changes in network architecture

35TB total country-

to-country capacity Internet backbone

Regional internet traffic

Need

• Optimize for DC and CDN based service delivery model.

• Keep pace with DC evolution: higher speed, more

capacity, better space utilization, lower power consumption

and more openness

Ken Florance, Netflix’s VP of

content delivery: “Our peak traffic

is more than that … . Our scale is

actually larger than the

international capacity of the

Internet.”

Levers

• DCI optimized networks: Disaggregation, purpose built DCI solutions

• 100G+ interface technology: PAM4, interoperable plain vanilla, flexi-rate and high baud rate

DCI Applications Constraints Open Line System Drivers

Cost/port and power density lead but …

… ease of integration and DC

automation is key, and… … requirement for Best-in-

Class functions emerging

Drivers for Purpose Built DCI Solutions

Disaggregation

• Why disaggregation

– Break incumbency and vendor lock-in, compete on a “best of breed” basis

– Quicker and decoupled cycles of innovation in each function

– Value to be gained from OpEx improvements, not just CapEx reduction

– Enables deployment of solutions targeted to requirements and business models of different providers

• What disaggregation is not

– Does not equal commodity

– Does not necessarily equal white box (though doesn’t exclude it)

– Is not about lowest common denominator

Other Considerations of Disaggregation

• How does the network operator ensure end-to-end optical

performance?

• Who is responsible for support and troubleshooting across domain

boundaries?

• How does the industry achieve interop for OLS with different

transponder technologies and suppliers?

• Pricing models still need to reflect value while changing to reflect

evolving technology and applications.

• There are other models of disaggregation for the industry to consider

100G+ interfaces segment into applications

Flexi-rate bandwidth variable transponders (BVT) • Engineered for highest performance, flexibility

and density

• SW switchable modulation and band-width-reach trade-off

Interoperable 100G • Engineered for lowest cost with medium

performance

• Interoperation through quasi-standard Staircase FEC (OpenROADM, black link)

• Pluggable options

Direct detect • White-light or colored PAM4

• Dispersion compensation needed

• Pluggables (QSFP28 or CFPx)
