Re: commercial launch
How time flies..when you're having fun and when the technology changes and the choices are growing in SDN and NFV. Reaping the benefits without getting confusion along the way might be easier said than done but the benefits in the long run will outlive the inconvience along the way we're all hoping!

Re: More Openness...
@kq4ym: I was talking to the lead in IT who is responsible for the design and implmentation of our SDN infrastructure and he made this point. The automation that comes with SDN is going to completely change the way we install, change and remove services, reducing lead times in just about every way. There are some serious considerations that need to be addressed for things like billing structures both from the carriers as well as from the VNF providers to make this as flexible as it can and should be.

Of course we still have last mile install intervals for new implementations, it will take a lot more integration (both physical and virtual) between providers to significantly improve that. As a global carrier I can see that integration happening a lot quicker in some countries/territories than in others.

Re: More Openness...
@mhhf1ve: I absolutely agree, SDN is going to foster a new era in the way the WAN operates. We have been talking about application performance being the key metric for how well a WAN works, but the tools, and frankly the application teams, have not been fully engaged. I am hoping this evolution brings with it a stronger focus on the application within the network domain. Perhaps I'm being overly optimistic, but if we have generic hardware and the willingness to support true open SDN, then application visibility and management should become a lot easier.

Re: More Openness...
 And I'd think that lots of folks are going to go for the hope that the "Lead times of months to deliver fixed function equipment is reduced to minutes," will turn out to be mostly true in lots of applications while keeping the costs in the long run under control.

More Openness...
> "Open platforms are key in eliminating vendor lock-in and driving growth in SDN"

This is a very important trend in the industry that I think will have significant impact to the entire vendor ecosystem. The era of proprietary hardware/software providing unique functions for carriers is coming to a close, and the next phase of developing unique services on top of commodity infrastructure will be a wild ride. 

Sure, there will still be room for proprietary algorithms running on top of all this commodity infrastructure.... but the era of open source is here to stay.

Re: name change?
@robuck: I think as the service providers get their SDN infrastructures in place, the focus will be on the VNFs and this will change things. Right now I think there is a distinction to be made between proprietary SD WAN and open SDN/NFV. Meraki is an example of what I would consider SD WAN. Unless things change pretty dramatically I don't think you'll see Meraki as a VNF, whereas some of the other SD WAN offers are built and available as VNFs today. I'm not picking on Meraki at all here, just using it as an example.

 

As we move into SDN/NFV type architectures across the board at the service provider level, the whole landscape will change. For now I think there is enough of a distinction between SD WAN and SDN/NFV to maintain the two terms independently. 

There is very definitely another discussion to be had about the orchestration and control of VNFs. You can either build your own open system (like service providers will do) or "pave cowpaths" (yes! I used it!) and end up with multiple, independent and proprietary orchestration platforms to control your SD network. You can tell my bias from that sentence, but I think this is really the revolution in networking.

name change?
Thanks John. What do you think of ONF's Dan Pitt proposing the phrase SDNFV? Are we to the point where one acronym will suffice for both?

Re: commercial launch
@John.Isch - thank you, interesting to know, I think SDN/NFV network solution is a right path for the company...

Re: Biz bennies
John - I'd like to claim credit for the term "paving cowpaths" but I've heard and seen it elsewhere. So feel free to use it!

Re: commercial launch
@robuck - I am not in a position to go into detail on that topic specifically with Orange's experience. However, there is an excellent report put out by NIA that shows some common problems. We, as an industry, have some distance to go, but it's a really exciting time to be in telecom!
