Voice over Wi-Fi Strategies white paper

NFV (Network Functions Virtualization) White papers Voice over Wi-Fi (VoWiFi)

This white paper describes how fixed, mobile and converged services providers can leverage Voice over Wi-Fi as a critical part of their mobility strategy. Native dialer and OTT app approaches are described based on the desired user experience, spectrum assets and overall business strategy. There are clear benefits for the user and the service provider, making VoWiFi a must have in any service provider portfolio. Metaswitch Cloud Native solution accelerates the path to VoWiFi, which increases agility and lowers deployment and operational costs compared to traditional IMS solutions without NFV platforms.

The application of cloud native design principles to network functions virtualization

NFV (Network Functions Virtualization) White papers SDN (Software Defined Networking) cloud native

Network Functions Virtualization is at the heart of the most fundamental transformation ever undertaken by the communications services industry, with profound impacts on technology planning, network engineering, operations and procurement.   And despite the enormous upheaval that NFV brings to their business, virtually every network operator in the world today accepts its vital importance to their future, and many have already made great progress in their transformation to a software-centric future.

The approach to NFV taken by the majority of network operators appears to be driven mainly from a bottom-up, technology-oriented perspective.  This narrative starts with the observation that most network functions can be provided by software running on commercial off-the-shelf server hardware at considerably lower cost than traditional proprietary purpose-built hardware.  The modern way to deploy software is with virtualization, and for virtualization at scale we need a cloud environment.  If we are deploying software in a cloud environment, then we can automate operations, and save ourselves a ton of operational expense.

Audio Transcoding and NFV

SBC (Session Border Controller) NFV (Network Functions Virtualization) White papers Media transcoding

Audio transcoding in the network is most often performed by Session Border Controllers. Traditional physical SBCs invariably make use of specialized hardware designed to minimize the cost, space occupancy and power consumption of the transcoding function. At the heart of that specialized hardware we find Digital Signal Processors (DSPs).


This white paper discusses the transition of the audio transcoding function from proprietary hardware-based SBCs into the NFV cloud environment, and sets out to answer the following questions:

  • How effective is today’s industry-standard hardware at performing audio transcoding?
  • To what extent do suitable acceleration technologies (e.g. DSPs) improve the effectiveness of audio transcoding in an NFV environment?
  • What are the practical aspects of deploying transcoding accelerators in an NFV environment?
  • How is industry-standard hardware evolving in respect of its ability to support audio transcoding, and how does that impact on decisions around the deployment of acceleration technologies for audio transcoding?

The aim of the paper is to give planners the tools they need to make informed decisions about how best to support audio transcoding in an NFV environment today and in the near future.

Located in the Irish Sea, midway between Great Britain and Ireland, the Isle of Man is on a mission. With the exception of the annual Tourist Trophy (TT) races that draw over 40 thousand people over a 2-week period, a slow decline in the historically important tourist industry meant the Island had to reinvent itself. It needed a new model.

“Telco-grade” in the cloud: deploying reliable VoIP in NFV environments

Fixed-Line Transformation NFV (Network Functions Virtualization) Cloud White papers high availability (HA)

Network operators want to take advantage of the flexibility, cost savings and increased agility that Network Functions Virtualization (NFV) offers them. However, they still need to provide traditional “telco-grade” services, including offering their end-users SLAs of five-nines availability or higher with strict call cutoff targets. Providing telco-grade services in the cloud presents a technical challenge but is achievable.

In this white paper, we examine the issues involved and show how network operators can achieve these goals.

Session visibility in a virtualized world

NFV (Network Functions Virtualization) virtualization Service Assurance Server White papers

Network operators must be able to diagnose and troubleshoot problems as they arise in the network. When there are problems, they need to be able to get to the heart of them quickly and efficiently. They need to reliably determine its root cause and address it, fast. Every second of delay could be hundreds of annoyed customers or thousands of dollars of lost revenue as peers route their calls elsewhere, and perhaps don’t come back. As network operators leverage Network Functions Virtualization (NFV) and Software Defined Networking (SDN) to rapidly roll out new services, increase service flexibility, reduce capital and operational expenditures, and become more agile, Service Assurance (SA) has struggled to keep pace. Part of SA’s struggle stems from the challenge of maintaining continuous SIP session visibility both within a virtual infrastructure as well as across hybrid physical/virtual environments.

The Network Software Provider: A New Vendor Category

NFV (Network Functions Virtualization) White papers Corporate

Network operators that embrace NFV will make fundamental changes to their supply chains. To minimize hardware costs, network operators will want to purchase their generic NFV infrastructure from high-volume vendors of general-purpose hardware, vendors that, in general, have very little knowledge of specialized network functions such as provider edge routers or IP multimedia subsystems (IMS). To procure the software that will provide those specialized network functions, they will need to turn to vendors that combine an in-depth understanding of the network functions with the ability to implement them efficiently in software on generic hardware. This is the type of vendor that we refer to as a Network Software Provider.
