Thank you I can use the headlight

Yes, the use of OSS definitely reduces the cycle time.

The security risks of OSS are really overly hyped.

Wish I hadn't missed this, although I do know a lot about open source and NFV. 

It's a great combination. For too long, network hardware was too closed. I'm glad to see things are changing for the better, that's for sure. 

does the network elasticy allow for scaling

will open source be goverend by structured body?

great point on clsoed source security

JohnGordon has made a good point.

ia there an industry where open source is used more that in the others?

There's definitely a lot of room for improvement.

thanks for the information.

Great talk - open source is something that seems to have a lot of misconceptions that can get in the way of implementing valuable resources for an organization.

thank you jim and kelsey! awsome lecture

Thanks for answering all our questions, @Jim! @Listeners great questions today, we'll see you back here next Wednesday for Using Open Source for Data Centers and Cloud Services with Roz Roseboro, Heavy Reading. Have a great weekend, everyone!

Thank you Jim and Kelsey! What a great class.

as long as you are not part of the ANONYMOUS collective >:)

Thanks again for the opportunity and for everyone who attended.

@egoldman16 Exactly. There are whole business models based on implementing/supporting/installing open source solutions. It also means more eyeballs on the code and more opportunities for collaborative innovation.

Thanks so much for the excellent lecture today, @Jim and for staying up late to deliver it, we really appreciate it!

what percentage of B/OSS are more monolithic vis-a-vis amenable to microservices?

(@ANON...: Try "profile update" on your profile page.)

@anon I'll contact you offline about your username, we'll get that changed!

B/OSS is definitey the rticky part.

B/OSS is a major focus for open source but lots of legacy there get on the way

We also utilize microsserivce architectur now which provides us a lot more flexibiity on OSS/BSS and other system integrations.


@Kelsey, no its been faster w/OS


Thank you, great presentation

We are integrated into our OSS/BBS. It is API driven trough an abstraction layer.


Thank you, great presentation!

Not to get off topic, but does anyone know of an easy way to change my name from ANON+ to something a little more friendly?

Good angles presented, looking forward to next lecture.

I believe it has taken longer to be implemented considering the maturity. Now you are seeing adoption across the industry and i expect that to ony accelerate.


@Jim: Another Listener Q: 

How do you integrate OSS/BSS with your orchestration?

Is it integrated - Has it been difficult?

Thanks for a great presentation

@enmansky Exactly. Isn't Apache open source as well? Open source doesn't mean "amateur" or disorganized

@Jim Listener Q: Do you think the development of standards for open source networks has taken longer compared to past adoption cycles within the communications sector? 

Thank you all for the opportunity.


Thank you for the presentation.

I understand it is the middle of the night there, Mr. Fagan, so thanks for giving up your sleep!

@ANON, my point was some Open Source ecosystems are robust and welll nourished and even have commercial support if enterprise wants level of comfort, while some open source software, shall we say, neglected or evolving haphazardly.

Thanks Jim for staying up so late for Upskill U!

Thanks, Jim, for a great presentation.  

Have always loved open source and am so glad to see the open source gaining so much traction via cloud.


@faryl: Agreed. Open source is an exciting community.

BSD Unix was open source.  Deviants, like AT&T, Irix, Solaris, etc., were not.

@JohnGordon I get the sense that people misconstrue "open source" to just be some sort of shareware and don't recognize the amount of development time & talent that goes into development. Wordpress & Linux are examples of open source that have robust vendor/developer communities that rival many proprietary systems

Do you think the development of standards for open source networks has taken longer compared to past adoption cycles within the communications sector? 

@ANON , what was "open source Unix"?

@egoldman16 - Linux is open source, based on open source Unix, which has been around since the 1970's.  

@faryl - totally agree. QA/testability is a separate question that is a function of feature set not due to open or closed.  A well written open (or closed) source will both be cheaper to test than a lousy closed system anyway

@egoldman16: Great point. The developer support depends sometimes on the "sexiness" of the project.

@rgruiam2jLI Can you expand on that? (Curious how that differs from proprietary)

i think there is opensource and there is opensource. Some segments are very well curated and some are more or less abandoned. So, you have to be specific when talking about open source. Linux is OpenSource.

(I would challenge the idea that there is a skill shortage in open source.)

How do you integrate OSS/BSS with your orchestration?

Is it integrated - Has it been difficult?

[email protected] Open source doesn't mean less-tested any more than proprietary means well-tested though. Many open source products have passionate & dedicated developers/users

@[email protected]: But maybe open source goes though the review of many developers in parallel, so that more is done in less time?

@[email protected] -- open source gets thoroughly tested.  tested on a level usually greater than closed source.  lots of eyes, lots of egos look at open source sw.

Have you factored in the extra costs of having to manage in-house an OpenSource solution?  Because in our estimation, this factor is never properly accounted for... 

You did not talk about testing. Close source products go through very long testing process, many months. Open source does not. So if you accept that close source product will be tested at the same level as open source, the cost of close source will be way lower.

Can you please give examples of network nodes that you have virtualized using Opensource NFV?


@Michelle - I completely agree

another Q for Jim: you started down this route with the aquistion of Pacnet -- how did you take the Pacnet culture into Telstra? Was it difficult with regard to NFV and open source?

TQM, Version control and production release management is a different problem than the question of open or closed source.  One can have a closed source that will still be problematic (what you expect an Apple-like UX while doing network functions?) and one can have open source but still be decent.  The execution and methodology question is always an independent question from capability of tools or raw materials.

Open source in typical SDLC actually allows some TQM by allowing peer review and white box evaluation especially for key components. But yes, just like all other devops, Agile or whatever new hip terminology, the culture/attitude and execution of principles is more important

great presentation so far - brb

Is Telstra looking at a combination of open source and white box solutions for PEN? 

are you 100% opensource?  how do you integrate your legacy vendors into your new platform?

Was it difficult finding Open Source developers?


Did you have issues with vendor lock-in before moving to open source?

There also can be a wider developer base to help identify & troubleshoot potential issues/bugs with security/implementation/etc

Is Telstra finding the same talent crunch when it comes to open source?

@israel no slide deck today

hi, everyone.. im ready to this course


Refinement of my reply to second poll question ("Has the implementation of open source in your organization significantly reduced development cycle times, or do you feel like there's still a lot of room for improvement?"): Open source reduces development cycle time, because of the leverage of the large development community.

no slides for today, sorry!

is there a slidedeck that I'm not seeing?  


a lot of room for improvement

Reply to human element in open source (concerning errors): The size of the community reduces the risk of errors.

OSS certainly has the potential to reduce SDLC.


a lot of room for improvement

You aren't paying vendor overhead w/Open Source

Security is a big issue in Open Source, as well as licensing variants are for Legal issues that can be buried in layers posing potential risk for fines etc that a company could face. The security issues can be managed and there are  several vendors of OSS scanning that can be leveraged to reduce exposure to vulnerabilities, or licensing issues, or a manual process can be used that is both cumbersome and time consuming, but no the security concern is not over blown, it is quite real.

No opinion, but I would guess that there is room to improve


still got improvement space

There are operating and maintenance costs to consider with Open Source

No, implementation of open source has NOT significantly reduced development time.


Q for Jim: how is Telstra using DevOps for its open source intiatives?

a lot of room for improvement


Has the implementation of open source in your organization significantly reduced development cycle times, or do you feel like there's still a lot of room for improvement?

Reply to second poll question: We grab open source when we can get it, if it meets functionality requirements.

reduced development time significantly

@ANON1249996548923  Open source will allow for an easier audit if there are legit questions on integrity of votes. The closed systems can and always be manipulated  anyway due to opacity


@gneangodgdav8 This has a really good list of what makes something open source https://opensource.org/faq

Security is my biggest concern in self-driving cars.

I believe security risk is not hyped, it is very important to take serious security measures.

Waiting on vendors to release fixes is painfully slow sometimes and at huge cost in many cases

Michelle -- re "Security is only as good as your team working on the project"  -- Doesn't the size of the team size and quality working on the project increase exponentially when the code is  open sourced? 



It looks like the testing is left up to the client/customer/impelementer. I wonder how many IT managers will buy such products?

More eyeballs on code before it's released into production can really help with the human errors

@TeleWRTRLiz I think that could be handle throught automation

(I'm not sure if I heard Mr. Fagan's questions clearly. There were three of them, and I"m afraid I mixed them up.)

If companies took security seriously, they'd hire a securtiy developer to test and contribute to the open source project, instead of being a free rider. Can't do that with closed solution...


What about the human element and risk for errors? How do you address that in open source?

Yes! is one of the pilars on a devops environment


Good afternoon everybody, I finally reached a spot with internet to listen to this lecture! It's 7 p.m.in sweden :)

Security is only as good as your team working on the project

Lots of discussion these days about potential voter fraud due to voting machine hardware and software.  Do you think these systems would be more secure if they were Open Source?

So over-hyped as a reason to be concerned just on virtue of using open source

Testing in production??????

It is always security...


Can you repeat those questions, Mr. Fagan?

I agree - there are vulnerabilities even in closed source software

Reply to poll question: The security risk is overhyped because, while the transparency may allow rogue users to try to find weaknesses and exploit them, those weaknesses are also more easily identified by developers and so quickly corrected by the community.

If you ask the security element vendors, it is not hyped.  But just like any open/closed source paradigm, open allows solution sources to come from the open world too. 


Another question: Am I correct to understand that Open Source does not translate into to free of charge?

Poll Question: it depends on the product ...some open source have thriving communities that are vested in keeping up with security measures, and there's the benefit of a large user base to help identify & address security issues that arise

Comes to security can it really be over hyped?



Security risk for opensource: I think it is overly hyped.  The security risk is no less or no more than proprietary software.


not hyped...I don't think telcos can be too careful with critical network infrastrcuture -- especially as business move to all digital

Not overhyped, maybe underestimated

Not overhyped - access to source makes the ID of vulnerabilities easier.  That said, there is a shorter time-to-repair CVE


Do you think the security risk of open source is overly hyped or not?

no security issue in my view.


No, they are real, but the risk has to be managed


open source is more secure.

A: I think it's over-hyped

overly hyped, but not non-existent

It sounds like Open Source helps level out the playing field

NO, it is not hyped overly.

This is a great follow on to Weds. Telcos and Open Source 101 class...it shows how telcos are using open source. 

Question for Jim Fagan: Do these Open Source providers have a standards consortium? I am thinking of inter-operability.

NFV = Network functions virtualization

(I wonder how many new entrants will materialize because of the lower barrier to entry due to open source.)

Network Functions Virtualization


Start thinking about what questions you would like to ask Jim!

@Jeff Network Functions Virtualization

Thank you!

NFV : Network Functions Virtualization?

someone might confirm

NFV means Network Functions Virtualization. You can learn more here at our Glossary and also take our four classes on NFV which are archived.

Question for Jim Fagan: What sort of support do these Open Source component providers offer?

@Jeff Robbins: NFV = Network functions virtualization?

@JohnGoodman I hear you - I use my iPhone, so certain scripts don't always run/show

@Jeff Network Functions Virtualization

@TeleWRTRLiz do you have a multipass?

What does the acronym NFV represent?

@aa I love the Princess Bride, too

Lately, I've decided that the Fifth Element is good!

Test question answer: Legends of the Fall :)

Reply to test question: My favorite movie (one of them, that is) is "The Big Country."

Thanks Jim for joining us at this hour!

Too mnay to have a favorite


The Notebook is still my favorite movie, although "Brooklyn" is about to replace that.

Stolen Kisses by Truffault.


any slids for this lecture?


We'll do our best to keep Jim awake. 

Is there any material that we can download?

@KelseyZiser: Then I applaud Mr. Fagan for his dedication in giving up part of his night to help us. Thank you, Mr. Fagan.

We have audio today. No slides, though.

@faryl: Thanks for the confirmation. I was afraid I had set up my browser incorrectly to see the handouts this time. (As a security measure, I use NoScript, and individually select which scripts should run.)

must be 1am in hong kong when it starts

Good afternoon from Brazil. Not Rio, unfortuantely


@John yes, it is the middle of the night where Jim is!

Checking in and saying hi from San Diego!
@JohnGordon I don't think there are any slides for today's presentation :)

Wow, Jim Fagan is based in Hong Kong? I wonder what the time is right now where he is. I hope it's not in the middle of the night!

Having trouble finding the handouts (if there are any?).
