Multi-access Edge Computing (MEC) offers application developers and content providers cloud-computing capabilities and an IT service environment at the edge of the network. This environment is characterized by ultra-low latency and high bandwidth as well as real-time access to radio network information that can be leveraged by applications.
MEC provides a new ecosystem and value chain. Operators can open their Radio Access Network (RAN) edge to authorized third-parties, allowing them to flexibly and rapidly deploy innovative applications and services towards mobile subscribers, enterprises and vertical segments.
Strategic relevance of MEC
MEC is a natural development in the evolution of mobile base stations and the convergence of IT and telecommunications networking. Multi-access Edge Computing will enable new vertical business segments and services for consumers and enterprise customers. Use cases include:
- video analytics
- location services
- Internet-of-Things (IoT)
- augmented reality
- optimized local content distribution and
- data caching
It uniquely allows software applications to tap into local content and real-time information about local-access network conditions. By deploying various services and caching content at the network edge, Mobile core networks are alleviated of further congestion and can efficiently serve local purposes. It is worth noting that MEC also addresses fixed and WLAN accesses.
MEC industry standards and deployment of MEC platforms will act as enablers for new revenue streams to operators, vendors and third-parties. Differentiation will be enabled through the unique applications deployed in the Edge Cloud.
MEC currently focuses on its ‘Phase 3’ activities that consider a complex heterogeneous cloud ecosystem. This work embraces MEC security enhancements, expanded traditional cloud and NFV Life Cycle Management (LCM) approaches, and mobile or intermittently connected components and consumer-owned cloud resources.
Our Role & Activities
The Multi-access Edge Computing (MEC) initiative is an Industry Specification Group (ISG) within ETSI. The purpose of the ISG is to create a standardized, open environment which will allow the efficient and seamless integration of applications from vendors, service providers, and third-parties across multi-vendor Multi-access Edge Computing platforms.
The initiative aims to benefit a number of entities within the value chain, including mobile operators, application developers, Over the Top (OTT) players, Independent Software Vendors (ISVs), telecom equipment vendors, IT platform vendors, system integrators, and technology providers; all of these parties are interested in delivering services based on Multi-access Edge Computing concepts.
The work of the MEC initiative aims to unite the telco and IT-cloud worlds, providing IT and cloud-computing capabilities within the RAN (Radio Access Network). The MEC ISG specifies the elements that are required to enable applications to be hosted in a multi-vendor multi-access edge computing environment.
MEC also enables applications and services to be hosted ‘on top’ of the mobile network elements, i.e. above the network layer. These applications and services can benefit from being in close proximity to the customer and from receiving local radio-network contextual information.
The work of the ISG includes development of normative specifications, as well as informative reports and white papers.
The DECODE Working Group is further focused on easing the implementation path for vendors, operators and application developers by providing SW implementation of APIs; developing a testing and compliance framework and a sandbox environment to be used in application development. All these are being made available through ETSI FORGE and in the case of the MEC sandbox, a dedicated portal.
Call for active participation
The various players in the value chain are invited to actively participate in the ISG and to contribute to the development of the specifications based on industry consensus. This is important, since it will ensure that the stakeholders are represented in this newly emerging ecosystem. The participants are encouraged to share best practices and demonstrate Proofs of Concepts (PoCs) and contribute to the various tasks of WG DECODE.
MEC have weekly Tech calls each Tuesday, noon - 2 pm UTC
MEC DECODE have bi-weekly Tech calls each Thursday, 3:30 to 4:30 pm CET/CEST, plus dedicated sessions during the plenary weeks.
A full list of related specifications in the public domain is accessible via the MEC committee page.

Hello again, and sorry for not writing so frequently. A lot of things happened in these busy months!
ISG MEC have updated some key Phase 2 specifications, and it is continuously progressing on the current Phase 3 work. I can only say “kudos” to the rapporteurs and actual leaders of this tremendous amount of work (you can find more information in the recent ETSI press release, and also details in this short summary.
A lot of time has passed since my last blog post, sorry for not reaching out to you, folks! Very busy period. Also, a lot of nice things are happening, and ISG MEC is continuously growing in membership, attracting new companies that are actively contributing to the standardization.
Our collaboration with 5GAA (now joining MEC!) is also well established with the identification of two MEC observers, Maxime Flament (CTO, 5GAA) and Luca Boni (Stellantis) who are acting as 5GAA representatives in MEC. The collaboration with Akraino is now also moving forward with the guidance of Jane Shen (Mavenir, Akraino TSC member and ETSI MEC Technical Expert) and Oleg Berzin (Equinix, Akraino TSC Co-Chair and PCEI PTL). Finally, we’ve recently held the 2021 edition of the MEC Hackathon (see results here, published as part of our renewed MEC Wiki page, https://mecwiki.etsi.org/).The MEC Sandbox is continuously updated with new functionalities, also used for the MEC Hackathon.
Last March 2021, I’ve started my new journey in ETSI MEC, taking over the Chair position from my friend Alex Reznik (HPE). Sure, of course I’m not a “beginner” in this group (as most of you who know me can appreciate that I’m there in the MEC Leadership Team since the beginning of the Phase 1!). Nonetheless, given the great work done together in these amazing years in collaboration with all MEC stakeholders, I’m grateful of the trust of many companies who elected me and expressed their warm support in my new role.
Last week I transitioned the position of Chair of ETSI MEC over to Dario Sabella from Intel. Having spent four amazing years serving as the Chair of this group, I am happy to see it in such good hands. For years Dario has been a significant contributor and an enthusiastic advocate of our work. He’s been the driving force behind many of our Hackathons. Moreover, Intel’s support and commitment for the group is a strong signal of our importance. The best days for MEC are in the future and this is where all of us should look. Still, leaving a position such as this, one does tend to reflect on one’s years of tenure and so for my last blog as Chair I am going to do just that.
I’ve been looking over some of my previous entries lately and noticed how many were touching on the subject of interaction between ETSI MEC and other standard and open source bodies. The subject is indeed still one of significant interest and the question about “fragmentation” and “competition” is one that comes up much too frequently.
Those of you who’ve read some of my previous musings on this subject might recall my position on this subject. Standards and open source serve very different functions: standards ensure interoperability between components where it may be necessary and open source provides implementations of such components. As such, the two types of bodies are highly complementary. Moreover, I’ve also maintained that even in the standards space itself little duplication of effort exists around MEC. Alas, hard evidence to support my view was previously missing – but that is changing fast.
Quite some time has passed since my last blog entry, and while I thought about a new blog a number of times, a good topic – i.e. one which is appropriate for discussion in a short, informal and public format - just did not seem to present itself. That’s not for the lack of interest or activity in MEC. 2019 is shaping up to be a critical year in which many operators are now public about their plans for edge computing, initial deployments are appearing and, as expected, holes in what the industry has been working on are beginning to be found (witness the much publicized and excellent Telefonica presentation at last month’s Edge Compute Congress). It’s just that it’s hard to blog about on-going work, even when it is very active, much less about internal efforts of various players in MEC. After all, what would that look like “this is hard and we are working hard on it…”
Nevertheless, the time has come. Those of you who follow my random MEC thoughts on a semi-regular basis might recall the subject of that last post ages ago (I mean in February): the need for both a vibrant Open Source community and Standards development in a space like MEC; and how the two are complimentary in that the focus is, by definition, on complimentary problems. And, if you don’t follow me religiously, here is the link: https://www.etsi.org/newsroom/blogs/entry/do-we-still-need-standards-in-the-age-of-open-source, grab a coffee, tea, a…. whatever … and read up!
There is a sense in our community that while industry-standard interface definitions are important, these do not have to come from traditional “Standards.” Instead they can come from a development community, e.g. from an open source project. Moreover, having these come from an open source project is better because the result is not just a document, but running code. Before I dive into this, let me be very clear: open source has had and continues to have tremendous and largely positive impact on our industry and beyond. It dramatically lowers barriers to entry into the market and in doing so enables small, nimble and highly innovative companies to play on a more equal footing with large established players.
But let me focus a bit more on whether open source eliminates the need for traditional telco standards, as many believe. To illustrate the point, I need to pick on a project, so let me pick on OpenStack. Not because it’s bad… quite the contrary because it is so very good and is quite important to our industry’s transition to NFV. As anyone who has worked with OpenStack knows, developing to the OpenStack API requires specifying:
- Which version of OpenStack you are developing to and which APIs you need.
- Which OpenStack you are developing to (RedHat, Mirantis etc.)
Yes, they are almost the same – but almost is not quite the same as the same. And when you are a small company, having 100 edge clouds that present almost the same interfaces still leaves you with the challenge of scaling to integrate with 100 different – slightly, but still different – implementations. In other words – you are still missing a standard.
This is not OpenStack’s fault, nor is it the fault of the several companies that harden and commercialize it for the market. The primary goal of OpenStack has been and remains to enable its users to get to market as fast as possible and to concentrate their investments where they believe they can add value to the base. Interoperability should be a side benefit (and good open source projects like OpenStack do try hard to maintain backward compatibility, etc.), but it is not a primary goal. In an ideal world, open source projects would utilize formally Standardized interfaces in those areas where these are needed – i.e. where large-scale inter-vendor interoperability needs are expected.
As the development of a Telco edge picks up steam with TIP, Linux Foundation and OpenStack all having launched large scale project focused on the telco edge, ETSI MEC is perfectly positioned to fill that role. Our service APIs are precisely the APIs that exist at the intersection of the needs of a large number (100’s) of global communication service providers (CSPs) and an even larger number (100 000s) of application developers that need to use services exposed by the CSPs. In such an environment a lack of standardization can be a significant barrier to the evolution of the market and we remain the only standards development organization focused on this issue.
Moreover, by serializing these APIs – see https://forge.etsi.org/gitlab/mec - we are enabling software developers (and yes, particularly open source developers) to easily integrate our work in their applications. No more reading standards documents in PDF! Furthermore, to accelerate and encourage the development of new and innovative services in this growing Telco edge ecosystem, we have recently established a working group (DECODE) to focus specifically on issues around enabling the use of these APIs in forums such as open source.
So the conclusion of this post is a call to action – we are here and ready to help you get the Edge done! Let us know how we can help.
One problem with summer holidays in our industry (or is it a benefit?) is that one tends to let certain things slide and to enjoy more time away from work – whether it be on a formal vacation or just by working a little less than our usual “40 hours” – a very loooong 40 hours – per week. I am certainly guilty of that this summer – and one of the things I am guilty of is not highlighting some really important output from the ETSI MEC ISG. But… as they say… better late than never. So here it goes, but let’s start with background and get to the cool things ETSI MEC produced as we go.
We’ve all heard that “MEC is a 5G technology” although what that means is not exactly clear. In fact, in my very first blog posting, I highlighted that this can lead to some of my (least) favorite “MEC myths”. Here those myths are, re-stated:
- MEC is a 5G technology, so until I roll-out a 5G network I don’t need to worry about it
- ETSI MEC will be made irrelevant as soon as 3GPP defines its AF/NEF
- MEC is only needed before 5G, at which point CUPS (meaning the UPF) replaces it
Side note: yes, the first and third statements are in fact mutually contradicting. But these are myths, they don’t need to be mutually consistent.
Clearly, I disagree with all of these statements, but what is the truth “according to Alex”?
Recently, one of the ETSI staff folks pinged me an e-mail that said, “Someone asked me ‘What is Edge’ and I could not quite reply. Can you help?” Well, come on! The answer is simple.
Edge is… and this is where I got stuck. Really, the answer depends… well… on who you ask and when or where you ask them. And this, really, is how some blog posts are born.
Let’s start with examples. Amazon seems to have a clear definition of what edge is – just look at Greengrass.
So there we are – the definition of the edge. Take your favorite cloud provider, one with the foresight to “extend” their cloud to on-prem deployments either on IoT devices or otherwise and that’s the edge. Well, that is an edge, and, perhaps in the world of Enterprise IT computing it is the prevalent type of edge, but in Telco (i.e. in the world of MEC) it is not – it’s just an edge.
Let’s start at the beginning, as the saying goes; and in the case of this blog that seems to be the question of what the group I work in – ETSI MEC – does, what it produces and how it fits into the overall Edge Computing ecosystem.
Coincidentally, this is related to one of my favorite myths, which goes something like this. “There are soooo many standards, industry bodies and open source groups working on MEC. With all of these organizations competing with each other, it’s not clear which one to choose. I think we need to wait for the dust to settle before doing anything in MEC.”
Like most myths, this one has a not-so-small core of truth. It is true that there are quite a few standards, industry bodies and open source groups working on Edge Compute related topics. And, it is certainly true that this has created a certain amount of confusion in the marketplace.
A blog about MEC? Well, as the chair of ETSI’s MEC ISG for a year now, I wondered what was there about MEC that could be said in a blog format; that would be of real interest to the community; that would have some chance of making me the social media superstar of edge computing?
This took some sleeping, but one fine sunny morning in Shanghai (during our very successful 13th plenary), I hit on an idea. One of the privileges of chairing a standards group is that you get to represent that group in various public events. And so, over the past year, I’ve been doing a good amount of public speaking on edge computing in general and MEC specifically. I’ve also been doing quite a bit of “private speaking” of a similar kind, as part of my day job at HPE.
Thinking back over all that speechifying on that fine sunny morning in Shanghai I realized that much of it is spent addressing the MASSIVE CONFUSION that exists around MEC – and that much of what I say is constant across the various venues and audiences. And so… why not use the tools of social media to get the message out and try and dis-spell some of that confusion.
Two weeks ago I had the pleasure to attend the Formula 1 Chinese Grand Prix in Shanghai. A pleasure not only because a German guy won the race; my real excitement, in fact, came from the world’s largest deployment of Mobile Edge Computing in a live network to date.
China Mobile and Nokia, at the Shanghai International Circuit, deployed an ultra-dense network of small cells and several MEC servers for providing a 5G-like mobile broadband experience. Spectators could follow the race from different in-car, trackside, and airborne camera perspectives and dashboards, all delivered in real time into an intuitive-to-use app. MEC made a huge difference in video latency and quality, which was testified by a user survey indicating high satisfaction and willingness to pay.
I had the great pleasure to represent the MEC ISG as ETSI MEC ISG chair and to present Mobile Edge Computing at the co-located 5G Observatory and Fog Networking conferences that took place on March 8-11, 2016 in Paris. Philip Lamoureux from Juniper represented the ISG at the MPLS+SDN+NFV world congress. Both congresses were endorsed by ETSI.
The congress attracted 1500+ attendees, coming from 65 countries, with a strong presence of service providers.
Mobile World Congress 2016 was busier than ever!
And Mobile Edge Computing was notably present at the event, on a lot more stands than in previous years. This certainly reflects the fact that meanwhile more than 60 companies have joined the ETSI MEC ISG.
The ETSI Mobile Edge Computing Industry Specification Group opens the door to wider innovation and value creation.
What is Mobile Edge Computing (MEC)?
MEC offers IT service and cloud-computing capabilities at the edge of the mobile network in an environment that is characterized by proximity, ultra-low latency and high bandwidth. Furthermore, it provides exposure to real-time radio network and context information.
Imagine how all this can be intelligently leveraged by applications to transform the mobile-broadband experience.
