Intel case study | Video & TCP optimisation for Tier 1 MNO

 

As mobile data usage continues to increase globally, it becomes ever more vital to ensure that mobile network infrastructure is optimised to maximise data throughput efficiently and continue to deliver excellent customer Quality of Experience. This case study looks at some recent System Integration work Digis Squared delivered to a Tier One Operator in the Middle East, which achieved over 30% improvement in mobile data downlink throughput.

 

Data growth – why optimisation will always be vital

Forecasts of mobile data growth are based on difficult to imagine numbers: exabytes.
1EB = 1 exabyte = 1000000000000000000 bytes = 1,000 petabytes = 1 million terabytes = 1 billion gigabytes

Whilst mobile data forecasts vary significantly – in the data set shown above, Ericsson and Cisco have a 75% variance in their 2026 forecasts – it is clear that mobile data traffic will increase significantly in the next 5 years.

With over 106 5G network launches so far globally [5], 5G is forecast to account for as many as 1.2 billion connections by 2025 [6], and the GSMA estimate over 20% of these mobile connections – a substantial amount of this mobile data traffic – will be carried over new 5G networks by 2026.

Data varies by source, but today video traffic is estimated to account for over 60% of all mobile data traffic, and some forecasts project it will increase to 77% by 2026 [1]. Therefore, the ability to optimise mobile data traffic, particularly for video usage, is of great importance to Communication Service Providers (ComSPs), and this is primarily achieved via the optimisation of TCP.

 

Video & TCP optimisation: vital for delivering excellent customer QoE

Transmission Control Protocol (TCP), is the key transport protocol for all internet traffic; it drives video streaming, file transfers, web browsing, and communications. Additionally, it establishes and manages traffic connections and congestion, handles transmission errors, and enables us to share resources with billions of connected devices, globally, simultaneously.

TCP is ever-evolving, to address new issues and continually improve optimisation as new technologies are deployed. Without efficient tuning, TCP can cause more optimisation issues than it solves. An optimised TCP implementation delivers increased goodput (lower error rate in data throughput), improved network efficiency, high TCP transfer speeds, lower retransmission rates, and more consistent TCP round-trip times – and who doesn’t want all of that?! All of this translates into improved Quality of Experience for customers, and as our expectations of device experience continue to rise, TCP becomes ever more vital.

With mobile data traffic rising exponentially, the increasing pace of 5G deployment, and growth in data-intensive video calls, video content and online gaming, the need for CSPs to optimise their network has never been greater.

 

Intel case study | Video & TCP optimisation for a Tier One Operator in the Middle East

In 2020 Digis Squared was selected by a Tier One Operator in the Middle East to manage the entire System Integration of end-to-end services and implementation for video and TCP optimisation on top of the packet core, over 3 core sites.

The solution implemented by the Digis Squared team was built with compute resources utilising 2nd generation Intel® Xeon® Scalable processors.

Yasser ElSabrouty, Digis Squared Co-Founder and System Integration Business Unit Director, explained that “Selecting Intel processors ensured we could confidently deliver the performance and reliable scalability that is vital for efficient and demanding TCP optimisation.  Customers’ expectations of QoE continue to escalate. The pandemic has normalised video interactions far faster than any forecast. We are all experiencing more video calls for communication to mitigate lack of in-person interactions with friends, family, clients and colleagues due to lockdowns and changed working practices. Plus, there is far greater use of video on social media and content platforms as we try to alleviate boredom and entertain each other. As 5G rolls out, people will expect continued improvements – buffering, patchy connectivity, dropped video calls all immediately impact network reputation. Maintaining efficient and optimised TCP requires solutions built on expertise, investment and the right equipment.”

“Working for this Tier One client, the Digis Squared team project managed the integration of this solution, selecting and managing vendors, implementing all elements of hardware and software, and optimising the solution to deliver the maximum efficiencies across the data network.”

“The project delivered considerable benefits to the client, and end customers. The Digis Squared project team benchmark data measured,

  • a 27% increase in processing cores [3]
  • 50% increase in bandwidth over previous generation Xeon processors [3]
  • 30% down link throughput enhancement, thanks to the data traffic optimisation achieved. [4]

We’re really proud of what we’ve been able to achieve for this client, knowing that their end-users will benefit from improved QoE that they can really see.”
