I can't believe I missed the live show! Looks like there was a lively discussion at the time.

Platinum

Thanks, Mike. And thanks again to you and Michael forthe good show today! :)

Thanks again Michael. I think those are some of the most well thought out answers we've had on a radio show. Great questions everyone!

Author

Good day to all 

Platinum

@Mike: If so, that'll be temporary until the next Heartbleed/Shellshock/etc., I suspect. And then confidence will creep up again. Attitude is news-cycle driven these days.

Re open source security. Yes a very big problem area for all parts of networks, especially as more software is involved. This is another issue like telemetry/analytics/automation in that it has to apply to each area of the network and all the servers on which the software runs. I'm not a security expert, since it is so pervasive that i feel I cannot cover it and cover the parts of networking that i cover now. Like many software efforts the priority usually goes: 1) make the function work, 2) improve the performance, 3) add management tools, 4) add security

@Joe yes, loss aversion much stronger motivator than potential gain. We feel worse about losing 50 cents than about not gaining $1

Author

Question for @Michael - Seems like carriers' concerns over security for open source have lessened...is that the case? Are they more confident about the security level of open source?

Author

Thanks for the show!

and as these new issues and problems arise, who has the skills to solve them. It's new territory for most.

Yes, the difference in time between planning to deploy and getting to actual deployment of SDN / NFV results from PoCs and trials, where much is learned about real world issues and problems, and then how to get to real automation required for the on-demand world. Wow, so many learnings every 6 months.We see lots of progress every 6 months, but then a new list of issues to be solved is added to the ToDo list. Telemetry/analytics, automation loopbacks are fine and good, but these must happen at the lowest level, that is in a particular network segment or use case at a time. We can't boil the ocean, but take a pot or bucket at a time.

Thank you - great show!

Author

Thanks Michael, and everyone that joined us today. Michael said he can answer a few more questions. 

Author

Is it fair to say that there has been a lot of enthusiasm, willing and effort but that network operators have hit a number of brick walls in terms of:

employee skills.

access to the necessary technologies from the supplier market

the realization that the data they hold on their networks, services and customers is to varying degrees inaccurate?

Author

Makes sense. They've already combined cable modems and Wi-Fi routers. Why not further consolidate?

Some MSOs we spoken with see SDN and NFV in the future embedded in the home and business cable modem gateways to deliver firewall and other services to business and consumer customers

but this is 2-3 year in the future. Meanwhile they need to get their software defined networks installed and working

 

could not agree more 

Platinum

@Michael: I type close to 120wpm... I could bury him all day. ;)

Thanks for addressing my question @michael howard!

Author

Comcast is very involved. Also look at who CableLabs hired--Don Clark and an exec from NTT who have been instrumental in NFV and SDN from the beginning as author of the original NFV white paper

 

@Ariella: True. But there's a lot of psychology that goes into how people perceive value, loss, and gain. (For instance, studies demonstrate that people feel better about their chances to gain in an investment if their chances increase from 90% to 100% than if their chances increase from 45% to 55%; sure, the former guarantees certainty, but in both cases it's the same 10% difference in probability.)

re Cable MSOs, they are all looking at SDN and NFV, some more vocal some more quiet about it

 

Hi..re SD-WAN and MPLS...it appears that it is that MPLS becomes incorporated as an integral part of an SD-WAN--you need the MPLS service still, but the coordination of application traffic between or among the MPLS, DSL, and LTE connections say

 

@Joe interesting data for sure. I wonder how long they expect to wait for that new revenue to roll in

Platinum

Michael is typing away. Just to further bury him, here's another from Joe:

QUESTION: re: all of this running on hypervisors... One concern that has been commonly voiced is that when you have a critical mass of VNFs running on a finite number of servers, vSwitches = bottlenecks. As SD-WAN and other VNFs continue to get deployed at an exponential rate, what can we expect to see in terms of hypervisor/vSwitch evolution?

Author

@Joe but either way, it translates into the bottom line in terms of money -- whether it's saved or earned

Author

Which, I suppose, leads me to yet another question for Michael:

Are you/IHS seeing moves to SDN/NFV/etc. motivated more by potential cost savings or more by potential revenue gains? What is the bigger "convincer"?

We'll get things sorted out with Michael. 

Author

@Ariella: You'd be surprised. There was a study a couple years ago conducted by Machina Research (I think commissioned by LogMeIn's Xively) that demonstrated that what more commonly sold companies/executives on implementing IoT initiatives was NOT the cost savings that everyone talks about -- but instead the promise of new revenue.

Hi Mike...technical problems. Im not seeing your poll or the audience questions

 

@Joe Yes, someone has to be making money in some way to make it worth the time.

Author

Great show, M & M. Good discussion. 

Steel

@Joe quite so, though I think the savings is what usually helps get the companies to sign on for tech

Author

@Ariella: The way to think about it is agility = new ways of making money, whereas avoiding complexity/fragilty = cost savings.

Digital transformation initiatives like virtualization often involve both.

From below Michael:

@Michael Howard Sounds like the conversation has changed from MPLS OR SD-WAN, to MPLS AND SD-WAN...what are your thoughts? Or is it an "it depends" answer?

Author

Really great conversation today -- thanks to Mike and Michael!

@Michelle audio just faded it out for me. I have to refresh to see the comments, and then it seems to take the audio away.

Author

Where is the chatboard? I've been listening until now...

 

Steel

@Joe some of those XCDs are amazingly accurate.

Author

Thanks for the show today, Mike and Michael! :)

great insights... :) :)  

Platinum

Thanks Mike & Mike! Great show, very informative!

Author

@Ariella: Open source or not, someone has to try to make money off of it. ;)

The future appears to be open source

Author

so it's all about agility, though saving costs is always good.

Author

I could link to that notorious XKCD comic on standards (Google it), but here's a better way of thinking about it, considering that standards are linked to non-profit organizations...

When I was a teenager, I had a summer job working for a non-profit theatre company in the box office.

One day, I overheard my supervisor and the General Manager of the theatre speaking about subscriptions and "profits."

Naive idiot 19-year-old me piped up, "I thought were were not-for-profit."

The General Manager, a big, jovial man, let out an enormous boffo, clapped me gently on the shoulder, and said, "Kid, every business is for profit."

quite a trail of software

Platinum

I'm not sure TEF would agree with the view that OSM wants to be 'aprt of ONAP'...

 

Author

IMHO, fragmentation -- when it comes to standards -- will always happen.

I guess Human Capital does not matter--does it--an implicit message for sure....

Platinum

audio is back now

I guess it was just me

 

Platinum

Shortage of employees, or shortage of market-rate employees located domestically? /skepticalcynicism

@michelle I still have audio

Author

Fine for me. And I;m on Chrome

 

Author

@mpouraryan: Obviously you need it, but enterprises are requiring more and more of it -- which led to my lackluster attempt at a joke.

audio is gone -- is it just me?

Platinum

@Adi: At this point, I tend to think "being in business" is increasingly that trigger -- at least, at enterprise scale.

Doing nothing, though, is not an option--it is an implicit message we all have to realize....:) 

Platinum

interesting discourse..I am not sure about all being "Drunk" on bandwith--it is an absolute necessity you all...as someone who has to grapple with it :) 

Platinum

So it seems like virtualization/SDN has become a solution to the complexities created by lock-in FUD. (relevant link)

Is there a particular scale/size/level of network complexity that is an obvious trigger for SDN?

 

Author

QUESTION PART 2: ...Or will it go away altogether? Will we see more reliance on bypasses like SR-IOV, DPDK, etc.?

QUESTION: re: all of this running on hypervisors... One concern that has been commonly voiced is that when you have a critical mass of VNFs running on a finite number of servers, vSwitches = bottlenecks. As SD-WAN and other VNFs continue to get deployed at an exponential rate, what can we expect to see in terms of hypervisor/vSwitch evolution?

audio is much better w/firefox than with chrome

Platinum

Hi all! Nice to see a busy room

Platinum

(Or, at least, that's the message the vendors are putting out because they don't want to scare customers away...but either way...) ;)

@Kelsey: FWIW, that's what I keep hearing from operators and carriers. MPLS/SD-WAN is increasingly not an either-or proposition.

@Mike: Thanks, that's what I thought (but wanted to make sure).

@Ariella: There's some joke in there about enterprises being drunk on/addicted to bandwidth.

@Michael Howard Sounds like the conversation has changed from MPLS OR SD-WAN, to MPLS AND SD-WAN...what are your thoughts? Or is it an "it depends" answer?

Author

Bring your own bandwidth, today's variation on BYOB

Author

@Kelsey I keep having to refresh to see the comments. That's why I'm on ly seeing your response now.

Author

That said, I think I tend to lean D (Network-based services) either way...but it's possibly close depending.

Revenue for SD-WAN vendors or revenue for their customers?

Is it fair to say that there has been a lot of enthusiasm, willing and effort but that network operators have hit a number of brick walls in terms of:

employee skills.

access to the necessary technologies from the supplier market

the realization that the data they hold on their networks, services and customers is to varying degrees inaccurate?

 

Author

Poll: Which SD-WAN service will generate the most revenue this year?

A.     Cloud-based subscriptions from vendors

B.     Services from carriers

C.     Services from vendors

D.     Network-based services

E.     Cloud-based services

F.     Enterprise services

G.     Integrated services

Author

@MICHAEL: What industries are demonstrating the most interest/deployment? And what industries seem to be the most reluctant right now?

@Mike Robuck mmhmm suuuure ;) @Ariella I'm using Chrome and the chat is loading fine

Author

@Michael Howard can we get a link to that survey later on?

Author

Relevant re: Telco Transformation reference: https://www.youtube.com/watch?v=F8mYLi3PGOc

Kelsey, and I didn't pay him to say it

Author

Audio working fine, but there is some delay on the chat. I have to refresh to see any recent comments

Author

haha like the Telco Transformation joke :)

Author

That's very much on demand 

Author

Good question @alanbreznick!

Author

i vote for deploying NFV first

 

Steel

Good .questions Alan and Joe

Author

what do you see cable operators doing with SDN and NFV  so far?

 

Steel

QUESTION IN ADVANCE FOR MICHAEL: To what extent (assuming at all) has the SD-WAN "boom" been contributing to increased interest in and deployment of SDN and VNFs in general?

Deploy SDN and NFV simultaneously -- or at least develop a coordinated strategy

Author

Re: Poll quesiton... I think it depends on the organization, its maturity, and how much it as to invest...but with a view to eventually deploying both.

Deploy SDN and NFV simultaneously IN A SMAL MARKET

Author

@Mike no problems with the audio here -- even though I'm on Chrome

Author

Deploy SDN and NFV simultaneously 

Author

same is on my end :) 

Platinum

Which path should carriers take in regards to SDN and NFV?

Deploy SDN and NFV simultaneously 

Deploy SDN first

Deploy NFV first

Do nothing, it's too complicated right now

Author
