Cloud-Native VNFs Ease On-boarding Process

NFV (Network Functions Virtualization)

One of the biggest frustrations that service providers currently have with implementing network functions virtualization (NFV) is on-boarding virtual network functions (VNFs). It’s a common refrain that on-boarding VNFs is very difficult. The reason why this process is proving harder than anyone expected is largely due to the origins of the VNF software – that is, was the VNF originally designed for an appliance or for the cloud?

Cloud Native is a Hot Topic

Industry Trends cloud native

I attended SDN World Congress in The Hague a couple weeks ago and among many meetings there I had a conversation with David Snow, Principle Analyst for IP Services Infrastructure at Current Analysis.  We both agreed that “cloud native” has become a hot topic in the NFV world of late, and I was able to share our views on cloud native with him.  He has just published a blog post on this topic at https://networkmatter.com/2016/11/02/microservices-how-cloud-native-are-network-vendors-today/

The missing link: VNF to SDN

NFV and SDN both play key roles in the ongoing evolution of telco networks to support flexible, programmable and composable services on a generic hardware platform.  The relationship between NFV and SDN in this picture is quite complex – but most experts would describe it in terms of layered architecture, where SDN takes care of Layers 1 through 3, and NFV address services at Layer 4 and above.  In a sense, virtualized network functions (VNFs) sit on top of a programmable network fabric provided by SDN.  And by “SDN” in this context, we are talking about the end-to-end network fabric, comprising both physical network functions that support wide area links and the virtualized network fabric that exists in data centers.

The Myth of the Carrier-Grade Cloud

NFV (Network Functions Virtualization) OpenStack Cloud Network Software Provider (NSP) Industry Trends

Many of the network operators that we are talking to about virtualized network functions (VNFs) are investing heavily in building specially engineered clouds for network functions virtualization (NFV). Others, however, are  looking closely at some of the commercial “carrier-grade” cloud solutions that are on the market. This cautious shopping for the perfect telco-like cloud seems to be one of the key reasons that NFV is taking so long to get into production.

NFV can’t be a clean break from the past; it’s got to coexist with what’s already out there in the network. And there are some good technologies that bridge that gap.

Open Source vs. Standardization

There’s a debate going on about how much we should let standards bodies specify NFV versus how much we should just rely on de facto standards. I think there’s a recognition that things move much faster if you allow de facto standards to emerge.

Open Platform NFV (OPNFV) and the ETSI NFV Industry Specification Group are both very much collaborative activities, and there is a lot of sharing that goes on. The collaboration has been around requirements and I think we will see some collaboration around the practical implementation of NFV.

NFV (Network Functions Virtualization) Industry Trends

Network operators have highlighted elastic scalability as one of the most important new capabilities that network functions virtualization (NFV) offers them.  In this article, we examine why elastic scalability is seen as so valuable, and how NFV supports elastically scalable network functions.
