NFV and SDN - Evolution Themes and Timelines

We recently held our first Virtual Networks SIG event in Cambridge Wireless. There were some great presentations. The one by the UK operator EE summarised everything quite well. For those who are not familiar with what NFV and SDN is, I would recommend watching the video on my earlier post here.

One of the term that keeps being thrown around is 'Orchestration'. While I think I understand what it means, there is no easy way to explain it. Here are some things I found on the web that may explain it:

Orchestration means Automation, Provisioning, Coordination and Management of Physical and Virtual resources.  

Intelligent service orchestration primarily involves the principles of SDN whereby switches, routers and applications at Layer 7 can be programmed from a centralized component called the controller with intelligent decisions regarding individual flow routing in real time.

If you can provide a better definition, please do so.

There are quite a few functions and services that can be virtualised and there are some ambitious timelines.

ETSI has been working on NFV and as I recently found out (see tweet below) there may be some 3GPP standardisation activity starting soon.

@zahidtg They can for virtualised networks. There is ongoing discussion in 3GPP for service chaining, vEPC etc.

Anyway, here is the complete presentation by EE:

Revolutionizing mobile networks with SDN and NFV from Zahid Ghadialy

There was another brilliant presentation by Huawei but the substance was more in the talk, rather than the slides. The slides are here in case you want to see and download.
