7 DEMONSTRATING MULTISPEED INTEROPERABILITY

From 10GbE to 400GbE Dave Estes, Spirent

June 18, 2020 Validating Multi-Vendor Interoperability

§ Who? 17 Ethernet Alliance members § Why? - Implement the most complex demonstration possible proving Ethernet’s robust connectivity/interoperability and compliance to Ethernet specifications demanded by emerging markets and applications - Highlighting the importance of testing early in an innovation’s development cycle to ensure interoperability and accelerate time to market

§ How? - Components (switches, routers, cables, optics, interconnects) ranged across various form factors and speeds interconnected with all compatible components and test and measurement solutions

www.ethernetalliance.org 9 Behind the Scenes @EA OFC20

The Equipment List

- It all starts with a list… - Months of careful collaboration with multiple participants on what equipment to showcase - Identifying demonstration details based on available vendor equipment - Mapping switches/routers including port counts & capabilities - Aligning cables/optics/fibers to compatible components - Dreaming big…

Enabling LIVE 400GbE network across multiple booths

www.ethernetalliance.org 10 Behind the Scenes @EA OFC20

The White Board

- Visualizing “minimum” number of connections to deliver maximum impact - Incorporating traffic routes and verifying interoperability (i.e. connections are operating error-free) - Optimizing available ports and interconnects - Diversifying showcase to highlight latest technologies and industry innovations

LIVE 400GbE network FlexE 100/40GbE testing AN/LT on 50GbE PAM4

The Hot Stage

- 17 participating vendors, 3 days of testing, all equipment onsite to build a fully functioning network - Testing every connection to ensure interoperability - Optimizing showcase with additional connections - Collaborating to resolve issues experienced - Testing integration with 200G/400G switch network - Displaying all connections in a single diagram

Thanks to all participants, and to Teledyne LeCroy for hosting the hot stage again this year!

14 ETHERNET CHALLENGES ON 400GE INTEROPS

Anabel Alarcon - EXFO

June 18, 2020 Tsunami Alert.. Flex E Rates Modulation Since 400GE appeared on the market a Form Factors complete ecosystem was born, including the following elements:

§ Form Factors (OSFP, QSFP-DD, CFP8)

§ Modulations (PAM4, NRZ)

§ And more flexible ways to transport ethernet traffic(FlexE)

www.ethernetalliance.org 16 Wide variety of interfaces

The different sorts of form factors and rates out there have generated an extensive variety of and cables.

As a test an measurement company we value a lot the opportunity to interop with new manufacturers and test new technologies on plug fests and interops.

§ That really gives us the opportunity to quickly adapt to market trends.

§ Also allowing us to create new tools. Example read registers, etc.

www.ethernetalliance.org 17 New challenges …

400G/200G transceivers and cables include a new type modulation PAM4(Pulse Amplitude Modulation 4) that has different characteristics and new challenges.

Key challenges

§ Three eyes per lane § Different electrical characteristics

www.ethernetalliance.org 18 New challenges new tools

PAM4 pluggables introduce a higher level of complexity, new flexible tools to test and validate them are required

1 2 3 4 5 PAM4 Eye Pre-Emphasis/ FEC Errors Validation RX Equalization (Power Multi-register diagram Consumption R/W & Temperature)

www.ethernetalliance.org 19 Different players

Another element inside ethernet networks is the increasing number of switch fabrics, on data centers, clouds, core, edge, etc.

Key lessons learned when testing these fabrics at interops:

ü Clean your fibers

ü Generate L2/L3/L4 traffic

ü BERT with different frame sizes (EMIX)

ü Smart loopback (very useful during interop’s)

www.ethernetalliance.org 20 FlexE Ethernet

Another member of the 400G ecosystem is Flexible Ethernet

§ The objective of this technology is to transport several mix clients with different bandwidth (5G, 25G up to 400G) using different high speed interfaces.

§ All the management is done at Layer 2, and its even possible to assign a specific mac address to each client.

www.ethernetalliance.org 21 Going forward ….

400G/200G Deployed massively

800G debut

400G/200G Coherent Optics

www.ethernetalliance.org 22 Summary

Ethernet ecosystem is growing more form factors, rates 1 and modulations

Interops reveal new manufactures, pluggable and 2 technologies

The industry requires teamwork, interoperability Thanks Dave you are the best 3 and have more FUN !!!

www.ethernetalliance.org 29 Summary

Cabling, Connectors, and Optical Modules are interoperable with leading switches, servers, and test equipment - even at 400G.

Ethernet Standards have created an eco-system where customers can choose components from multiple vendors over multiple data rates and have them all work together.
