Telco Cloud Deployment Tracker: Open RAN deep dive

Telco Cloud: Open RAN is a work in progress

This report accompanies the latest release and quarterly update of STL Partners ‘Telco Cloud Deployment Tracker’ database. This contains data on deployments of VNFs (Virtual Network Functions), CNFs (cloud-native network functions) and SDN (Software Defined Networking) in the networks of the leading telcos worldwide. In this update we have added some additional categories to the database to reflect the different types of virtualised / open RAN:

  1. Open RAN / O-RAN: Fully open, disaggregated, virtualised / cloud-native, with CU / DU split
  2. vRAN: Virtualised CU/DU, with open interfaces but implemented as an integrated, single-vendor platform
  3. Cloud RAN: Single-vendor, virtualised / centralised BU, or CU only, with proprietary / closed interfaces

Cloud RAN is the most limited form of virtualised RAN: It is based on porting part or all of the functionality of the legacy, appliance-based BU into a Virtual Machine. vRAN and open RAN are much more significant, in both technology and business-model terms, breaking open all parts of the RAN to more competition and opportunities for innovation.

Accordingly, the report presents data on only open RAN and vRAN deployments however a granular analysis of each category of RAN deployment can be carried out using the Telco Cloud Tracker tool.

Open RAN and vRAN deployments, 2018 – 2022

Open RAN and vRAN

Both Open RAN and vRAN are virtualised (with the exception of NTT DoCoMo as outlined in the report), but ‘open RAN’ implies full disaggregation of the different parts of the RAN (hardware, software and radio), and open interfaces between them. By contrast, vRAN incorporates the open interfaces but is generally deployed as a pre-integrated, single-vendor solution: hardware, software and radio supplied by the same vendor.

To date, there have been significantly more open RAN than vRAN deployments. But vRAN is emerging as a potentially competitive alternative to pure open RAN: offering the same operational benefits and – in theory – multi-vendor openness, but without the overhead of integrating components from multiple vendors, and a ‘single neck to choke’ if things go wrong. Deployments in 2020 were mostly small-scale and / or 4G, including trials which continued to carry live traffic after the trial period came to an end.

The stark contrast between 2021 and 2022 reflects a slight hiatus in commercial deployments as work intensified around integration and operational models, trials, performance optimisation, and cost economics. However, major deployments are expected in 2022, including greenfield networks 1&1 Drillisch (Germany) and DISH (US), Verizon, Vodafone UK, and MTN (Africa and ME).

Scope and content of the Tracker

The data in the latest update of our interactive tool and database covers the period up to March 2022, although reference is made in the report to events and deployments after that date. The data is drawn predominantly from public-domain information contained in news releases from operators and vendors, along with reputable industry media.

We apply the term ‘deployment’ to refer to the total set of VNFs, CNFs or SDN technology, and their associated management software and infrastructure, deployed at an operator – or at one or more of an operator’s opcos or natcos – in order to achieve a defined objective or support particular services (in the spreadsheet, we designate these as the ‘primary purpose’ of the deployment). For example, this could be:

  • to deploy a 5G standalone core
  • to launch a software-defined WAN (SD-WAN) service
  • or to construct a ‘telco cloud’ or NFV infrastructure (NFVi): a cloud infrastructure platform on which virtualised network services can be introduced and operated.

The Tracker is provided as an interactive tool containing line-by-line analysis of over 900 individual deployments of VNFs, CNFs or SDN technology, which can be used to drill down by:

  • Region where deployed
  • Operator
  • Technology vendor
  • Primary purpose
  • Type of telco cloud function deployed
  • …and more filters

Telco Cloud Deployment Tracker: 5G standalone and RAN

Telco cloud 2.0, fuelled by 5G standalone and RAN, is on the starting grid

This report accompanies the latest release and update of STL Partners ‘Telco Cloud Deployment Tracker’ database. This contains data on deployments of VNFs (Virtual Network Functions), CNFs (cloud-native network functions) and SDN (Software Defined Networking) in the networks of the leading telcos worldwide. It builds on an extensive body of analysis by STL Partners over the past nine years on NFV and SDN strategies, technology and market developments.

5G standalone (SA) will hit an inflection point in 2022

5G standalone (SA) core is beginning to take off, with 19 deployments so far expected to be completed in 2022. The eventual total will be higher still, as will that of NSA core, as NSA 5G networks continue to be launched. As non-standalone (NSA) cores are replaced by SA, this will result in another massive wave of core deployments – probably from 2023/4 onwards.

NFV Deployment Tracker: North American data and trends

Introduction

NFV in North America – how is virtualisation moving forward in telcos against global benchmarks?

Welcome to the sixth edition of the ‘NFV Deployment Tracker’

This report is the sixth analytical report in the NFV Deployment Tracker series and is intended as an accompaniment to the updated Tracker Excel spreadsheet.

This extended update covers seven months of deployments worldwide, from October 2018 to April 2019. The update also includes an improved spreadsheet format: a more user-friendly, clearer lay-out and a regional toggle in the ‘Aggregate data by region’ worksheet, which provides much quicker access to the data on each region separately.

The present analytical report provides an update on deployments and trends in the North American market (US, Canada and the Caribbean) since the last report focusing on that region (December 2017).

Scope, definitions and importance of the data

We include in the Tracker only verified, live deployments of NFV or SDN technology powering commercial services. The information is taken mainly from public-domain sources, such as press releases by operators or vendors, or reports in reputable trade media. However, a small portion of the data also derives from confidential conversations we have had with telcos. In these instances, the deployments are included in the aggregate, anonymised worksheets in the spreadsheet, but not in the detailed dataset listing deployments by operator and geography, and by vendor where known.

Our definition of a ‘deployment’, including how we break deployments down into their component parts, is provided in the ‘Explanatory notes’ worksheet, in the accompanying Excel document.

NFV in North America in global context

We have gathered data on 120 live, commercial deployments of NFV and SDN in North America between 2011 and April 2019. These were completed by 33 mainly Tier-One telcos and telco group subsidiaries: 24 based in the US, four in Canada, one Caribbean, three European (Colt, T-Mobile and Vodafone), and one Latin American (América Móvil). The data includes information on 217 known Virtual Network Functions (VNFs), functional sub-components and supporting infrastructure elements that have formed part of these deployments.

This makes North America the third-largest NFV/SDN market worldwide, as is illustrated by the comparison with other regions in the chart below.

Deployments of NFV in North America account for around 24% of the global total of 486 live deployments (or 492 deployments counting deployments spanning multiple regions as one deployment for each region). Europe is very marginally ahead on 163 deployments versus 161 for Asia-Pacific: both equating to around 33% of the total.

The NFV North America Deployment Tracker contains the following data, to May 2019:

  • Global aggregate data
  • Deployments by primary purpose
  • Leading VNFs and functional components
  • Leading operators
  • Leading vendors
  • Leading vendors by primary purpose
  • Above data points broken down by region
  • North America
  • Asia-Pacific
  • Europe
  • Latin America
  • Middle East
  • Africa
  • Detailed dataset on individual deployments
