The network edge is evolving. Consumer and enterprise applications are becoming more demanding, requiring higher bandwidth and lower latency. In order to meet these demands, a new category of network edge infrastructure is being developed, called Multi-access Edge Computing (MEC).

MEC is a standards-based architecture that allows operators to move compute and storage resources closer to the end user, while still maintaining the centralised management and security of a traditional data centre.

MEC is an important part of the 5G roadmap and is already being trialed by leading operators around the world. In this article my aim is to provides an overview of MEC, including its key benefits, use cases, and deployment considerations.

What is Multi-access Edge Computing (MEC)?

MEC is a network edge architecture that offers the capability to host applications, services, and virtualised network functions on servers that are closer to the users than a traditional cloud-based data centre architecture. The servers are connected to the core network via high-speed connections.

MEC enables applications and services to take advantage of “edge computing” – the ability to process data closer to the user, reducing latency and enabling new use cases.

MEC increases the agility of the network and enables operators to build applications and services that are specifically tailored to the needs of their customers. It also optimises network resources, reducing traffic on the core network, and enables operators to deploy more applications and services to their customers at a lower cost.

MEC is an Internet Engineering Task Force (IETF) standard, which means it is compatible with a wide range of existing and future technologies. This means that operators have a wide range of options for deploying MEC and can take advantage of existing technologies and tools.

Benefits of MEC

The benefits of MEC are many, but here are some of the most important ones:

• Reduced Latency: The increased proximity of servers to end users reduces the latency of applications and services, resulting in improved user experiences.
• Improved Robustness: MEC servers can be seamlessly integrated with the core network, providing improved redundancy and improved network availability during unexpected network outages.
• Increased Capacity: MEC allows operators to offload some of the traffic from the core network, providing more capacity for applications and services.
• Improved Security: By keeping applications and services closer to the user, MEC reduces the risk of data being intercepted by malicious actors or unreliable sources.
• Faster Deployment of Applications: By leveraging existing technologies, MEC allows operators to quickly and cost-effectively deploy applications and services.
• Customised Services: MEC can be used to create customised services tailored to customer needs.

Overall, MEC is an invaluable tool for operators looking to provide improved services to their customers, reduce costs, and increase their market share.

How MEC Works

MEC is based on the concept of edge computing, which involves utilising distributed computing facilities that are located closer to the end user. This distributed architecture is made up of nodes that are located at the edge of the network, such as on user devices, at the base station, or in the vicinity of the end user.

These nodes communicate with each other and the core network to provide an end-to-end solution for applications and services. This allows for the offloading of traffic from the core network and the deployment of applications at the edge of the network.

MEC is enabled by network slicing, which allows for the segmentation of the network into multiple virtual networks. This allows for the creation of customised virtual networks for specific applications and services, allowing operators to maximise the use of resources.

MEC is also enabled by edge analytics, which involve collecting and analysing data from the edge nodes and the network to identify network issues and provide insights into user behaviour. This allows operators to quickly address issues and customise services to improve the user experience.

Use Cases for MEC

One of the biggest advantages of using MEC is that it can bring applications and services closer to the end user. This helps reduce latency and makes applications and services faster and more responsive.

Here are some use cases for MEC:

• Edge Computing for Automotive: MEC can be used to enable a variety of automotive applications, such as vehicle-to-vehicle communication, route optimisation, automated driving, and accident avoidance.
• Low-latency Gaming: MEC can be used to enable low-latency gaming applications, where a short delay can make or break a game.
• Augmented Reality and Virtual Reality: Augmented reality and virtual reality applications require the processing power of MEC to be able to render a realistic environment in real-time.
• Industrial Internet of Things: Internet of Things devices in industrial settings require the low latency and processing power of MEC to enable real-time control of the devices.
• Online Learning: MEC can be used to enable online learning applications, where students can interact with content on the edge without having to wait for content to be downloaded.

Summing up MEC

MEC is a game-changer for a significant number of key segments the IT industry as a whole. By bringing applications and services closer to where they are needed, latency is reduced and applications and services can be made faster and more reliable.

The potential applications and use cases of MEC are virtually limitless, ranging from automotive applications to low-latency gaming to augmented reality and virtual reality to Industrial Internet of Things to online learning.

Although there are challenges, such as the need to ensure network security and the amount of capital investment necessary for deployment, the potential of MEC is too great to ignore.

The need for lower latency and improved reliability have never been greater, and MEC appears to be the technology that can address these concerns. With the seemingly limitless potential of MEC, we can expect to see tremendous growth in this field in the years to come.
