Redefining Mobile Content Delivery with NFV and MEC

 NFV Fast Track to InnovationNetwork Functions Virtualization (NFV) essentially separates the physical underlying infrastructure and the software computational level.  NFV architectures leverage the scalability, performance and cost effectiveness of commercially available hardware platforms which can flexibly run multiple virtualized software function nodes.

In mobile networks NFV implementations can be adopted across the entire network; from the Radio Access Network (RAN) to the Core network. While ‘getting there’ requires a sizable initial investment in the mobile network, the benefits to mobile operators cannot be dismissed.

Here are some NFV benefits:

  • Efficient network management
  • Economical network maintenance
  • Real time network optimization
  • Fast introduction of new services and apps, without the physical restrictions of HW infrastructure

And there is more. NFV architectures open the door to network innovation. By separating software from the underlying hardware infrastructure, NFV ‘frees’ the functionality layer enabling us to re-think and re-imagine mobile network functions. By throwing into the mix an additional architectural paradigm; Mobile Edge Computing (MEC), we can push mobile network frontier all the way to the Radio Access Network (RAN).

Let’s take a look at mobile internet. Mobile networks typically route all traffic from the Internet, into the core network, through the transport network and across the radio access before finally reaching the user device. This includes, of course, rich data and video. With such a long journey to travel, it is no wonder that mobile internet is slow.

Now, let’s see how we can turn things around for mobile internet with smart software virtualization inside the RAN.

Saguna, a true fan of NFV and pioneer of mobile edge computing, is using smart software virtualization technologies to redefine content delivery in mobile networks. Based on fully virtualized software nodes, Saguna CODS platform brings the internet into the mobile base station; as close as possible to mobile users.

Here is where it gets interesting. Typical solutions that serve content to mobile users from the base station are unable to support mobility (a basic requirement in mobile networks) and bypass the core network functions including billing, policy enforcement, etc. The lack of mobility limits the service and monetization possibilities.

Saguna’s NFV solution routes the content directly to the user and within the mobile network. This innovative approach preserves user mobility and all core network functionality. With Saguna’s NFV solution mobile operators can offer acceleration services such as DNS Caching to improve webpage download speeds. The RAN-based NVF platform can be used to connect with 3rd party content providers creating new premium service and monetization opportunities.
