Three Reasons, Edge needs an All-in-One, Compact MEC Platform!

Jan 27, 2022

Edge computing, 5G and the emergence of new ultra-low latency sensitive services for MEC (Multi-access Edge computing) have shifted the way telcos are perceiving their mobile networks.

They see edge clouds as a new potential to monetize their network. It also enables a new way to work with partners like application developers, over-the-top players (OTT), and telecom equipment vendors.

But to get all these benefits, telcos need to build edge data centers the right way.

And the wrong way is to build it like traditional centralized data centers. For example, adding platforms and servers can easily lead to a build-up of platforms that are both CAPEX and OPEX intensive.

So what is the right way: Build an edge data center with a smarter all-in-one and compact platform for MEC.

Here we give three reasons, why an all-in one compact MEC solution is the way to go for edge data centers

 

Reason 1: Limited Space and Power necessitates an all-in-one and compact MEC platform

Generally, the small edge data centers do not have the luxury of space and power.

A compact MEC solution that has integrated networking and compute functions can help here.

Compare the setup on the left side with that on the right side.

Building stacks of ToR switches and servers on the edge of a data center consumes space and a lot of power. Also, it needs a lot of connections and patch panels.

The setup on the right side is compact All-in-one MEC hardware and suitable for small data centers. It is an integrated MEC platform with compute and networking all in one box. It is easier to install and maintain.

The result is power and space savings, which translated to low OPEX and ultimately high cost savings.

 

Reason 2: Diversity of Services

Edge is a hub of very diverse services. For example:

  • Low latency and/or high throughput services like IoT, AR/VR, Autonomous Vehicles, Gaming, CDN in, etc
  • Radio Access Network (RAN) components like CU, DU
  • Components of 5G core network like UPF
  • Networking layer

Above all, running these different services in a multi-vendor and heterogeneous environment at the edge means that potential additional security risks can happen as the network surface has expanded. Therefore, necessary security functions should run at the edge as well.

To support all these functions, there is a risk that telcos can introduce multiple siloed solutions at the edge, which is not efficient and cost intensive. Instead, an all-of-one MEC platform can provide an open compact cloud to run all these multi-vendor VNFs, both as VMs as well as containers, under one orchestration system that results in cost savings.

 

Reason 3: Lines between compute and networking are blurring

The programmability of the networking hardware opens new and innovative opportunities for the service provider beyond the traditional networking capabilities. It opens doors for the application developers to develop new user cases.

Consequently, lines between compute nodes and network switches are blurring as networking switches become more powerful and programmable.

P4 combined with programmable ASICs makes networks do more than traditional connectivity functions.

Programmable networks today can offer rich analytics, in line telemetry ( INT) as well as offload security functions like stateful firewall from compute layer to  the networking layer.

Above all, 5G UPF, that otherwise needs to be run in the compute node can be offloaded to the networking switch thanks to P4 programmability. This use case is the initial focus of the SD-Fabric project by ONF.

Today’s all-in-one MEC platform enables a tightly integrated networking and compute layer, which is possible through the use of programmable switches inside the MEC platforms.
