  • Walked over to the Ethernet Alliance booth, will be a great collaborator wioth OFCnet
  • Walked over to the Open Roadm booth, met there prof. Andrea Fumagalli from UTexas in Dallas.
  • Key is to find out what the concrete extra value will be when all these booths will get connected together and on the wide area optical networks.
    • What will they prove? Interop?
    • What applications will they enable?
    • How will they work together, what is their incentive?
  • Got exhibitor badge.

Prepared the info that I had as contribution from the UvA to the CIENA - OFCnet booth:



  • conference center WIFI is really bad, not more than 1 Mb/s
    • The OFCnet connection is one Million times faster than the entire bandwidth for the wireless!
  • wired is very expensive 10 Mb/s => 10k$
Went to special session on pandemic in 1AB. https://www.ofcconference.org/en-us/home/program-speakers/symposia/reflections-on-the-pandemic/
attendance looks low to me, similar to 2020.
  • Steve Alexander (CTO - CIENA)
    • talking about uptake of connectivity and digital divide
  • second speaker from NTT (Daisuke Shirai)
    • about video uptake during pandemic
    • utilization of optical network

  • subject: 5G to optical network convergence on the showfloor with connectivity to data via Fabric to Bristol and U Amsterdam data Exchange
  • Needs support from CIENA, is good candidate to propose for funding
  • Also couple in 5G work from Chrysa Papagianni
  • Another longer term opportunity is the coupling of classical and quantum networking only on the show floor.
  • look at TIP
  • quantum on showfloor
  • convergence scenarios with cellular
  • OFCnet use as 5g to att and verison
  • UBristol bring mobile network
  • work 5g for campus

10h15-10h45 Had an presentation and panel (Clark, Scott, Marc, me) in EXPO 3, Marc presented the slides, I gave some remarks, led the panel and entertained Q&A.

  • Explained the experimental nature of OFCnet, you are allowed to fail (if you do not fail you did not try hard enough)
  • features:
    • Capacity
    • Capability
    • Security
    • Network Convergence
    • Up to applications
  • Breakable network
  • long RTT across the world
  • Dark Fiber onsite and off-site (e.g. Quantum)
  • Attention on the entire range: components -> devices -> networks -> Applications
  • Different tracks: qnet, cnet, bnet, wnet, etc

Walked tech program and show floor.

Steve came to the booth just before exhibition closing time. Explained him: The OFC WIFI of the convention center never gave me more speed than 1.5 Mb/s
OFCnet was 1 million times faster at 1.6 Tb/s!

The OFCnet efforts have been successful. We had first light and we succeeded in making the case for such facility to many people from the Optica organization and the show floor participants. Marc is now well established as mr. OFCnet.


Had a brief after chat with Steve, Scott and Mark. All signs are green.
Wrapped up around 15h30, got the car to pick up the server from UCDS and left the conference.

Flight was smooth. Landed around 8h35. 10 minutes taxiing. No line at immigration. Half hour waiting for luggage.

Some epilogue:

Jim Steward (UEN) mailed me his thoughts in the form of a SWOT on OFCnet

Strengths
  • knowledgeable and experienced group of dedicated technologists who can draw from past similar efforts
  • OFC leadership support
  • CIENA leadership support
  • Infrastructure in place, especially fiber connectivity
  • CENIC, SDSC participation
  • Engineers and competent technology staff involvement
  • Location and infrastructure
  • Research focus
Weaknesses
  • expensive
  • Diminished willingness to travel
  • Development will evolve over years, delayed results
Opportunities
  • live network connecting booths on the floor to the outside world
  • Multi-vendor/carrier environment providing dev and lab environment opportunities
  • Participating vendors have access to researchers and other industry experts
  • Industry experts, researchers and other interested participants have access to a multi vendor, multi carrier environment
  • Opportunities to define research on a working network, prepare experiments, conduct experiments and publish results, also potential for invited talks and posters
  • Involve NSF program managers, develop NSF funded workshops
  • Vendor provided trainings and workshops, e.g. OTDR, fiber splicing and management best practices, OEO, etc.
  • OFCnet tour and other vertical tours
  • Training opportunities for OFCnet staff
  • Networking (professional relationship building) for all involved
Threats
  • withdrawal of support or perhaps under commitment from key stakeholders
  • Drawing from other older, established conferences and forums may be perceived as threatening
  • Fewer resources available going forward
  • Supply chain issues
Some of my final thoughts:

OFCnet
  • A problem we face is the 90-9-1 rule on the exhibition floor:
    • 90% components vendors
    • 9% device/interface builders
    • 1% network builders
  • OFCnet is geeky new, but also really needs new demonstrators and new organizations to attend.
  • With some work we may line up as first movers:
    • UCSD PRP-folks
    • Ethernet Alliance
    • OpenRoadm
    • U-Bristol+UVA on 5G-Optical convergence and smart city data exchange
  • For the future
    • Quantum Networking demonstrations on the showfloor only
  • To attract demo's and Proof of Concepts and Net-Building
    • set up a challenge and price / honorable highlighting in opening plenary
    • Make use of the EXPO's
  • To attract Academia
    • Awards for a number of categories
    • a birth of a feather and or workshop track
  • To think about
    • Should we have an equivalent of a top 500 list?
