thank you , good info/ideas

Open networking is certainly the future!

Many thanks for a great presentation and discusion.

Poll question answer: very important I believe.

Answer to bonus question: I believe a Cloud, analytics platforms and internet

I guess service agility first. And reduced costs in long term.

Test question answer: swimming is my fav. olympics sport :)

I'm excited to see the momentum of CORD and open networking.

@Guru: Thanks for answering my question!

Isn't vendor lock-in really just a FUD term, though?

Thanks all! What a great class @Guru and @Larry. I learned a lot, that's for sure.

Thanks everyone for your interest and participation. I am gong to sign off  now. 

Check out the details at http://opencord.org/ 



Thanks @Guru and @Larry for the excellent presentation today, for addressing our many questions, and for a great slide deck as well! Listeners - excellent questions today and thanks for your responses to the bonus question, I'm enjoying this discussion! We'll see you back here next Wednesday for the start of our Open Source series with OpenDaylight on Telcos & Open Source 101

Good question about density and performance one can get with proprietary boxes vs open. We are starting to see some amazing merchant silicon from chip vendors and more and more OEM vendors are using those silicon anyway. Still there is a trade off -- proprietary solution that offers some advantages over open solution with no vendor-lock in. We think for the infrastrucure, service providers willing to give up that extra edge with proprietary for openness and white boxes. 

@John: Indeed, this is the point that many people often miss in the security vs. accessibility debate.

Reliability is a balancing of those two interests.

About reliability, XaaS means getting your high-availability using best-practices in elastic cloud services -- from SW instead of HW! As for developing regions, the low-cost nature of CORD is exactly what companies like Google ane Facebook are looking for as a platform for delivering access services to the next billion.


Further reply to bonus question: Perhaps it is too obvious, but the internet backbone of everything as a service needs to be reliable, otherwise it all goes out the window, which means XaaS will be hard to implement in developing regions.

(Yay!  Thanks for asking/re-posting my question, Kelsey!)

Ooops. I meant we are NOT focusin on class 5 switches. 


@Guru/Larry: Another listener q: 

If you go with an entirely open infrastructure, how do you mitigate the performance and port-density issues at the center of the datacenter core that proprietary boxes have traditionally been best suited for?

We are focusing on legacy class 5 switches as much... We believe they have been already replaced with softswtiches and CORD will definitely integrate softswithces well. I must admit I am not as familiar with state of class 5 swithes in today's network and providers are not asking us for that. 

About security, a lot of people talk about micro-services. What XaaS gives you beyond a micro-services architecture is a separable service control plane, which is where we enforce the operator's security policy.


@John: Excellent point.  It's difficult; that's for sure!  I believe it can certainly be reasonably secure -- and certainly more secure than cloud and IoT solutions are today, in general.

Great presentation. Was thinking that any transition costs could be mitigated via colocation or other business model.

Eh, technically speaking, security isn't strictly "essential" either (though highly desirable).  Security and accessibility are the archnemeses of each other.  Perfect security means complete inaccessibility, and perfect accessibility means complete insecurity.  Accessibility of some non-zero degree is vital (and the whole reason we're talking about this subject to begin with -- because these technologies and platforms and standards help enable accessibility) for what we are talking about.  Security, strictly speaking, is not.

But that said, from a practical perspective, yes, it should be secure -- just as every technological solution should be secure.

While CORD has focused initially on today's established business units (Enterprise, Residential, Mobile), it's the opportunity to do more in the IoT, Virtual Reality, gaming, etc. spaces that's most exciting.


IOT is one of the use cases of M-CORD and we are exploring connectionless in that context. 

And look at Analytics for CORD (A-CORD) -- where we are trying to enable closed loop control with programmabile proboes, monitoring as a service and anlytics based control. 


Reply to "bonus" question: Certainly security is important, but I wonder if "everything as a service" can be secure.

About billing end users -- alwasy important -- one of the things CORD enables is a pretty powerful "self help" portal, where users can opt into (and out of) services dynamically. Having a LAN party... dial up the bandwidth and maybe even spin up an on-demand virtual network. (Certainly the latter will happen fairly soon for enterprises.)


I disagree with those saying that virtualization techs are "essential" to "everything-as-a-service."

"Everything-as-a-service" necessarily implies IoT -- and the sensors and other IoT devices are too small at this point to be able to virtualize or to make it worth deploying virtualization.  (Sure, you can virtualize the cloud itself, but that is not strictly vital for what we're talking about here.  Cloud is essential to XaaS, IoT is essential to "EaaS", and big-data analytics is essential to IoT.  Q.E.D.)

1) Support heterogeneous delivery (OS, container, legacy appliance-based)

2) Secure

3) High visibility for analytics and assurance

@Guru/Larry - a lot of listener questions coming in! Here's one for you: 

how do we have legacy class 5 switches migrated to CORD?

Some carriers are looking at using DWDM for CO to CO communication or for large service providers or enterprises using it, because ONOS is a distributed fabric they have been successful in building optical bypass portions with YANG models, TL1 or OF 1.3.1 using the optical experimental fields.





security, cloud, analytics

This was a very clear and understandable presentation of the CORD concepts.  Thank you Larry and Guru.

It was a great session, thanks a lot to all of you.

i agree: internet access, IOT, and data analytics

Cloud is the first one, then Internet Over Things and BIG Data  analytics.

thank you for an excellent lecture.


willingness to colloborate - looking to help all vs just their own objectives - ability to scale

About taking control back from cloud operators, I think CORD puts the conventional operators back in the game, but everyone wins. It's likely some (perhaps many?) of the functions loaded into CORD will come from Facebook, Google, etc.


Cloud, Data Plane, Control Plane

I will say CORD will help services take off... And yes that requires a control plane that makes it easy to plug-in services and manage them.

BONUS question! What are three essential ingredients needed to build an XaaS (Everything as a Service) paradigm?  

@John: The "bonus question" was asking what the "three essential ingredients" are for an "everything-as-a-service paradigm".

Thanks, all.  Great discussion

Can you repeat that question?

Thank you! Great job!


Thanks for the excellent presentation

ingredients: security, analytics, open source

Thank you.  Very interesting.


Missed the CORD Summit last week

how do we have legacy class 5 switches migrated to this cord ?

seperation between data and control plains and white box hardware


very interesting, thank you


Guru and Larry -- Thanks for a great presentation!

What was the "bonus" question again?

Good Onboarding program, Governance, Scale.

3 essential ingredients:

1) Cloud.  (Duh.)
2) IoT.
3) Big data analytics.

Thank you for the presentation

Thank you for sharing with us and taking the time with us today

Great, we want more on this topic

Thanks for this great show, Guru and Larry (and Kelsey and the rest of the UU/LR team!).

Great job! (and very nice slides as well)

Thank you! Very interesting!

It's been fun. Thanks.


Yes important to coordinate with RAN vendors and we are. If you see the list of partenrs and collaborators you will see RAN vendors. 


Does CORD bring control back to the service provider from the cloud operators?


In other words, CORD can help the control plane take off.


I'll see myself out.

Acces (GPON, vOLT, etc) has been mentioned in this CORD presentation.  Has transport (i.e. DWM) been considered for CORD implimentation?



Are disaggregated data-plane parts of OLT and BNG "off-the-shelf" and standardized? 


Right now the PMC-Sierra PAS5211 GPON SoC for OLT communicates to the vOLT Agent using indigo, netconfd, the proprietary APIs for the PMC silicon and an OMCI stack.


Do the southbound hide all protocol-specific data and diagnostics (like PLOAM and OMCI in GPON), or are they exposed to NFV developers? 

how far is Cord from actual commercial deployment

with the feature creation and scalability enhancements what would be the triggers to bill the end users?


@dfperson: And more savings on top of that!

Central offices are typically considered highly secure.  How does CORD emphasize security against the growing threat of attacks against Internet infrastructure?


How important is it to coordinate CORD efforts with exiswting RAN vendors?

i see the co moving from 48V DC to computer flooring, ac power, etc


Question: What about O&M? Does the vOLT integrate with existing provisioning and operations systems? Or is there another O&M required?

The transition costs are one-time. If they have an acceptable return on investment, then it probably won't matter too much what the initial level is, if it's reasonable to expect an acceptable ROI on the investment (and the credit or the internal funds are available).

ALL i can say  that this topic is very interesting, and I would like to see more of it


Less trucks mean less liability and savings on insurance too

This class will be archived and available 24/7 right after the live class ends.

Great info. Could you send out a recording.

Question: Most OLT/ONT GPON soltuions are mostly proprietary interfaces based on common standards. Is there a special integration or restricted set of ONTs that can be connected to the vOLT?

Indeed, it's not just about costs.  It's about savings.

And, on top of savings, you can add active value on top of that.

Do u have a refernce VolT implementation that can be used


Service agility directly affects cost, so service agility.


@Faisal - Ciena acquired BluePlanet, which gave them a commercial ONOS Controller distribution.

How do you distribute the CORD functionality between the CO?

mobile slides here should be updated to either represent SGW as SAEGW, or to add PGW. SGW->CDN communication can't happen.

Can you share with us the most discussed solution in opposition to the CORD approach? Is there a competing viewpoint?

In a contantly evolving ecosystem, how do the operators make a full service transition and still expect same service levels are with traditional approach?

what is Ciena role, Ciena is an optical company but does not have OLT or Router etc

How costly is the new Architecture /Cord in the CO?


how do we have legacy class 5 switches migrated to this cord ?

How is the realiability and 5 9's availabiloty aspect handled in the software? TYradiitional hardwares haven been more realiable.

@Faisal: I am of the impression (speakers, inter alia, correct me if I'm wrong) that CORD is but a virtualization platform that uses NFV.

Assuming the providers and owners of the Cental Offices all get on board - what is your best guess at when 1) implementation at the first CO would happen and 2) 100% implementation across the US---i.e. 20 years? 5years?

If a Service Provider wants to use CORD but wants to maintain some services on their old model, can both operate side by side in the new Datacenter?

How is CORD different than NFV. What I am seeing is all what NFV promises, commodity servers, virtualization etc....i dont see any difference

@Guru - what if i want to use ODL instead of ONOS? or FD.io? or OSM instead of XOS? What about a combination of Openflow, NetConf, REST (less likely), BGP-LU/BGP-LS, etc? 

Service agility is the main driver


Can CORD be adopted as a Core Network implementation? Or pretty much limited to Access side?

Listener poll: What's the biggest long-term benefit of CORD? Reduced cost, service agility, or do the two go hand-in-hand?

Question:  Is the Open Networking Lab related to ONF, Open Networking Foundation?

Is CORD model applicable to cable operators?

Is OnLab partnering with any groups like OPNFV or ONOS or are their any partnerships in its future?  

Where is the QoS in this picture. Per se QoS can't be virtualized, since it has to be performed at particular physical point within data path. This fact interracts with the wirtualization somewhere in the "cloud".

Open source has flexibility and accessibility, and I'm guessing cost savings. However, I can see how open-source central offices will commoditize the industry, and drive the most efficient providers into dominance of the industry.

That said, my instinct says agility.

But I'd want to think about this some more.

Reduced cost and service agility -- the two go hand-in-hand.

This will not reduce costs so long term busines agility would be the main benefit


Reply to second poll: Biggest long-term benefit of CORD is both (the two go hand-in-hand).

Both go hand in Hand - Cost Reduction and Service Agility

Agility, costs are not going down

Service agility and reduce cost

Service agility first then cost.


The two (svc agility + reduced costs) do NOT go hand in hand.  You can be cheap AND non-agile.  ;)

More cost than service agility.


Agility. Absolutely. Businesses don't grow by cutting costs. 

cost and avoid vendor lock in

hand in hand for long term solution

Eventually they go hand in hand


R-CORD the residnetial one is in field trial at AT&T. We have done POCs for M-CORD and E-CORD and continue to build on them with the community. 

AND ANOTHER QUESTION FOR THE SPEAKERS: The general perception in the industry remains that proprietary = enhanced security.  How do you rebut this?  And (part 2 of the question) how do you advise people in their organizations to rebut this proposition and open colleagues up to the idea of moving to a more open solution?

Most of the service providers are coming to the realization that thre is no real reason to differentiate at the infrastrucure level per se. And so they are wiling to adopt somehitng like CORD. We have over 20 providers around the globe very interested in using and build on CORD. 

Is Openflow a necessary element or there are alternatives ?

QUESTION FOR @GURU: Given that CORD is an integrated platform, how can everyday participants help contribute to it?

How far is CORD from reality?

Welcome, GACou!
(And all other newcomers)

Is OLT avilable in all CO? if not whatwould be the alternate point of connectivity?


OPNFV and CORD have similar goals... CORD arctheiture is different from OPNFV in specifics. 

CORD is an integrated solutions platform that the community can use and build on. We have demonstrated how CORD can be used to support residential, mobile and enterprise custoemers. 


Hate losing control of my network to my provider.  

Since April of this year, my provider seems to have enough trouble providing current services and I don't want to burden them with anything else.

Currently, are all the owners of the Central Offices in the U.S. on board with this transition or are there competing strategies regarding the future use of the Central Office?

QUESTION: Are ther any interoperability issues when connecting CORD using whiteboxes and OSS to the upstream networks, like peering with upstream routers?

CORD uses ONOS for SDN controller/OS, XOS for service life cycle management and service composition, OpenStack and Docker for virtualization so yes we are building it on other open source platforms. 

in CORD, focus is on access. In other ONOS use cases, we focus on the core as well. 


Still don't understand how CORD is different from OPNFV?

Its very very important that the COs use industry-wide adopted technology so they can be outsourced easily

QueSTION FOR SPEAKERS: If you go with an entirely open infrastructure, how do you mitigate the performance and port-density issues at the center of the datacenter core that proprietary boxes have traditionally been best suited for??

Is your focus only on the access part of the network ? or also core network?

Most OLT/ONT GPON soltuions are mostly proprietary interfaces based on common standards. Is there a special integration or restricted set of ONTs that can be connected to the vOLT?

How is important to Extends the agility of micro/Cloud?


What would be the Capex and Opex to convert a CO to a open source based SDN/NFV/Cloud Datacenter ? What will be needed in retraining IT/Engineering employees in maintaining this new infrastructure ?

It's relevant, thereby making it more important than "not important," but "somewhat important" -- especially in this three-pointed survey -- seems to suggest some substantiality.

We're not at all at the point where we're ready to leave proprietary boxes behind (security being one of many issues/reasons) -- and they still can and do have their place -- as with whiteboxes.

based on the industry maturity annd roadmap, when do you think carriers such as ATT would start proeuction implementaion?

Having things as a service is great.

Very important. if you go through all the process of converting to this architecture, why would go with grey or open/proprietary technologies


The telcos datacenter in general need an overhaul

How important do you think it is to build the CORD with white boxes and software VNFs? Not important, somewhat important, or very important?  

Is there an option between "somewhat important" and "not important"?

Very important from service provider perspective


Very Important to enable Open source.

So, CORD is both an open source project and an architecture now, but is prescriptive in the way the architecture is realized (ONOS for controller, XOS for service orchestration, OpenFlow for programmability). How does CORD (the open source project) evolve to encompass the divergent views on programmability and control plane?

Very Important as this is the fabric on how Carriers can stay vendor neutral.


how do we have legacy class 5 switches migrated to this cord ?

Very important, expecially VNFs

When you say PON, you mean OLT ?


Reply to first listener poll: Very important.

@Joe Stanganelli yeah it seems nothing has changed

What kind of open source platforms are being referred to in the slides? Like what specific projects?

How is CORD different from OPNFV?

Do you think multiple CO's will consolidate into "super CO's" so to speak - Or is there an advantage of EACH existing CO to become a data center?

@daniel: In the old days (and even still today), the idea of turning your central office into a datacenter has typically meant keeping your server in the janitor's closet.  ;)

Respectfully, as beneficial as open source can be for various use cases and for all the pros and cons of open source vs. proprietary, I vigorously disagree with the go-to argument that proprietary inherently inhibits innovation.  Does open source encourage innovation?  Sure, it can.  (It can also encourage a lot of bickering over standards and nothing real getting done while huge bugs persist.  Open source is "open" in that way.  ;) )  But that doesn't mean the lack of open source is inherently inhibitive.

CORD has been the major focus of ONOS.  Why is CORD being separated from ONOS?  What is the CORD and ONOS relationship moving forward?


CORD seems very ambitious project. making CO as data center

sound is working perfectly for me

@mhixson try refreshing your screen

Do you invision the CO will become more of an "open facility" or stay primarily proprietory to the owner of the CO

40-50 years old -- there you go @Daniel

I think the central office is pretty ancient if you think about it @daniel!

@Bleung, try to turn up the volume on your computer.

I like how the central office in this slide looks ancient...

how can I get adjust the sound control , it is hard to hear


very intereting topic, heard quit bit about cord

Hi from Thousand Oaks, CA

Hi, everyone , from warm saudi arabia


@vzcam ha! My favorite is gymnastics

Don't forget there are slides for this presentation so be sure to download them from above. We are looking forward to the discussion, so be sure to post your questions, comments and thoughts on the message boards.

I don't usually watch any of the Olympics

Wonder if telcos are moving COs to DCs so they can be outsourced along with other DCs

My favorite Olympic sport is boycotting the Olympics and watching something else.

hi for Chicagoland! Fav olympic sport: Gymnastics and cycling!

@daniel: Welcome and hi!  How's the weather there today?

And hi all others, too!

Should be a good presentation

Swimming and Table Tennis.

track  - pole vaulting


Favorite Olympic sport is gymnastics.

Beer is my favorite Olympic sport. 

Hello from Northern California!

There are slides for this presentation so be sure to download them from above. We are looking forward to the discussion, so be sure to post your questions, comments and thoughts on the message boards.


I'm ready for this to start!

QUESTION: Will open source inhibit implementation of breakthrough, but proprietary, architecture and software that might make data centers more efficient?

Interested in learning more about new concepts around the central office – would seem to me that everything should become more and more decentralized!

QUESTION FOR GURU RE: SLIDE 10 (eventually): Certainly SDN and NFV go with the cloud and boost its power substantially (and vice versa), but the Venn diagram confuses me.  Aren't XaaS and cloud (by itself) essentially synonymous?

Hello ... looking forward to a presentation

Hello world...I'm ready for today's webinar.

Hi, guys!  Looking forward to this show in particular!

Greetings & salutations all!

Look foward to hearing Guru speak on this topic! Already have my slides downloaded :) 

Hi @Guru, can't wait for your presentation!

Good Morning from St. Louis, MO

Good morning... Looking forward to our conversation. 

Hello! Looking forward to this presentation.

Good afternoon to you, too @MrBruce!

It's incredibly muggy here in North Carolina...ready for Fall to arrive!

Hi everyone! Great to see that the chat board is already quite lively! The slides to accompany today's presentation are up - you can download those from the link above the chat in the "Special Educational Materials" section.

Can't wait to hear the Guru speak!

Looking forward to talking about CORD's architecture with the class.

@cdt Yes! We record ALL of our courses so you can listen to the recording anytime. Recordings are available immediately after the course ends.

Are these courses ever replayed in case I am unavailable during the live stream?

@Timcasto1 it depends on how many times you post to the chat board - so you could move up from Light Beer to Light Sabre and then to Lightning. Maybe Guiness should be between Light Beer and Light Sabre? ;)

What does "LIGHT BEER" signify? I prefer Guiness.


This chat board is rockin' already! Really looking forward to tomorrow's class with Guru and Larry and all the discussion. 

hope to attend should be interesting 

Great session. Looking forward for more!


Really looking forward to this lecture. Looks like a great topic with a great presenter. 

Hi All! Good opportunity to refresh my knowledgements.

I am also looking forward to the discussion

thanks for the invite looking forward.

Looking forward to this perspective - this will be huge change to the environment


I'm really curious about the future of the central office. I'm looking forward to learning more about its transition or total replacement by data centers. Curious developments for sure!

Registering for Aug. 3 tele

should be a great event!
