@wa51e4, Yes, F5 is involved in PoCs of NFV with major carriers.  At this point, we cannot disclose who we are working with, though.  :)

Light Beer

@uditharansara If the orchestration is done right, the additional latency should be minimal.  One concern for NFV, though, is performance.  Proprietary hardware performs better than virtualized services on VM solutions.  It is understood that some services or network locations will have high performance requirements that may not be suited for virtualization and NFV technologies.  Those will be addressed as they are identified, though we have the advantage that OTS perofrmance continues to increase over time and will eventually catch up to the requirements.

Light Beer

There are multiple PoCs in development.  As mentioned, Telefonica is working on one in Latin America to virtualize the CPE devices.  The functions of the CPE such as DHCP and NAT are moving to a distribution point that will be virtualized.  There are other major carriers worldwide that are doing PoCs for NFV technologies and even modifying their next generation architectures and procurement based on the NFV principles.  NFV is real and here to stay.  And, as mentioned, it makes sense.  This is the application of a lot of the technologies designed and proven for the cloud environments and leveraging them for the service provider core networks.

Thanks to everyone who participated and great questions, crew!

So sorry, Jim has wrapped for today but he did provide his email if you want to send a follow-up question.

Blogger

thanks, Jim, for your PoC info. also, in your slide 5, what is the Network Hardware listed in the hardware resources layer?  switches? routers? servers? what is the requirement for it?

Light Beer

Okay folks, we need to wrap up today's session. Thanks to Jim Hodges and Frank Yue. Great job, guys.

We have covered on Light Reading a number of planned PoC trials (Telefonica and SK Telecom mentioned) so definitely starting. Expect a lot more next year

Light Sabre

regarding dwillson's question on TDM-IP; my response would be that given the nature of the TDM physical interface this is an example of a function that can't be virtualized; but the control of said function and the orchistration there of can be. Yes Jim ??

Light Beer

Frank, can you also address the PoC trial question?

 

Blogger

@dwilson I believe that the voice traffic is protected not because of NFV technologies initially, but because of the IP technologies being applied to voice traffic.  QoS parameters, traffic prioritization and other technologies can be applied.  Then from a NFV perspective, when there is a need for resources to be applied to voice services to scale and provide availability based on service bursting through NFV orchestration. to ensure that services are always available.  As Jim says, orchestration is key and the ability to collect and analyze data to process is important.

Light Beer

is there a real PoC trial going on or planned somewhere or this whole thing is just pie in the sky slideware? i'm really curious. did F5 do anything?

Light Beer

is there any real performance test.....

Excellent question, again I think it will have to be assessed via a PoC trial

Light Sabre

The expectations are that sevice latency will be similar or better than the traditional model

That of course means positioning and orchestration of the VNFs will be critical - which is why I stressed the orchestation role

 

Light Sabre

How is voice traffic protected when TDM-to-IP transition takes place and this traffic flow is processed in a virtualized data center

Light Beer

is there any real performance test on using general purpose servers to do virtualized firewall?  how many and what kind of servers are needed to push 10G worth of traffic?

Light Beer

What about the expected service latency for the virtualized solution?

What kind of impacts may cause having userplane traffic processing in the cloud including DPI?

Light Beer

If you have any questions about how I mapped the criteria feel free to contact me at [email protected]

 

Light Sabre

Jim and Frank are joining us now.

dwillson - sorry I didn't get to that question,

Thank you Jim and Carol

Light Beer

Thank you very much for nice explanations

Light Beer

Orchestration is in NFV or SDN layer?

Light Beer

You mean NFV > SDN > SDRas SDR the lowest layer?

Light Beer

What's happening on the pricing front ? What are vendors doing to enable such an agile spin-up/spin-down as required s/w environment on a licensing/per seat/per sub etc. basis ? 

Light Beer

That is very interesting point that CAPEX saving is not much. Would you please show real data (or link) of comparison of CAPEX and OPEX?

Light Beer

Are there deployments where the edge functionality is being completely virtualized but is being moved to the core? In that case, the edge device would be just a 'dumb' NID, no?

Light Beer

@sumsin The audio portion is above this chat area. You can push play and the audio should begin. Below that is a link to download today's slide deck.

Light Beer

I am logged on to the webpage. Cant find the link for the webcast. Can you pls give me the link.

Thanks

Light Beer

For Home/SMB kind of environments do you envision that we will have embedded platforms running Hypervisors with multiple VMs executing different VNFs? What kind of Packet Processing speeds are we looking at for these kinds of platforms? What kind of vendors are cureently in this space?

Light Beer

Usually people mix terminology SDN/NFV. Would you please clearly define those two?

Light Beer

Thanks all.  Seems to be working fine now.

Light Beer

So the fellow now speaking is Frank Yue, technical marketing manager of F5 Networks.

Blogger

Yes, Chrome is much better in general - use it for a few days and you'll never go back to IE. 

Blogger

Mine too (intermittent) with IE. I should open on chrome. Chrome is much better than IE

Light Beer

try refreshing your page or using a different browser. Chrome and Firefox seem to work the best

 

Light Beer

ibrown, usually when that happens it's a bandwidth issue. Our quality control folks tell me they are hearing the audio clearly. 

Sometimes there are also issues with firewalls. 

Blogger

Thank you carol for the link.

Light Beer

The live stream is intermittent on my end.  Is this a local issue or a general issue with the stream?

 

Light Beer

You can find the NFV White Paper on the ETSI NFV ISG site, which is here: http://www.etsi.org/technologies-clusters/technologies/nfv

Where can I get the NFV White Paper? Would you please give us link?

Page 3. How to shift HW to SW focus?

Light Beer

how does NFV protect real time traffic when congestion occurs?

Light Beer

Jim Hodges. Thank you very much for kind explanation. It gives better understanding.

As illustrated on today's slide page 4, classically there are many equipment and servers for various tasks (functions). Classical meaing of virtualization is that making virtual compute/storage/network on the server or on the cloud.

NFV means that you put some (or all) of the functions into each virtual cluster? Or just make the server virtualization?

I'm looking forward the webinar.

Light Beer

Greetings all, looking forward to this session. Don't forget to submit your questions as they come to you. I will be asking some of your questions during the live discussion and our speakers will be joining the Live Chat when we finish talking to address anything they haven't already answered.

Also, don't forget to download the slide deck above.

looking forward to this session

Hello Wonoh.Kim. Essentially, NFV proposes to take telco software for a specific network function, say for a CSCF and virtualize it so it can run on a standard server. This server with NFV is in the data center and accessible via the hypervisor, just like any other data center application would be. Therefore, it moves network functions from the network domain to the IT or Data Center domain. This means NFV functions referred to as Virtualized Network Functions (VNFs) can run in the cloud and be "spun up" as required in response to traffic requirements.

Light Sabre

Hi Everyone! Don't forget to download Today's Slide Deck to follow along with Jim's presentation. You can also feel free to post questions here on the message board at any time and we'll answer them either live over the broadcast or here in the chat area. Looking forward to an interesting discussion!

Light Beer

I'm still confused on the concept of NFV and Virtualization. I wish that I can understand through this webinar.

Light Beer

Looking forward to Class tomorrow and understanding NFV!
