The Edge Is No Longer Just About 5G As ETSI Reveals MEC Phase 2

The ETSI Multi-access Edge Computing group (MEC ISG) has announced its first set of Phase 2 specifications for Multi-access Edge Computing – so-called because it became clear soon after the group’s establishment about two years ago, that Mobile Edge Computing, as it was first called, had to be extended to transparently encompass wired access connections as well as wireless due, amongst other things, to the large telcos pursuing converged, broadband services. The ETSI MEC group now has more than 85 members,

The first fruits of that broad change in approach are now coming through and ETSI says the updated specifications incorporate the widened scope of ETSI MEC to apply to any access technology and take into account integration with network functions virtualization (NFV).”

At present, the picture is complex and getting more so as potential applications come flooding in.

These days you have to have an edge story and as a result the edge appears to have more positions than the Kama Sutra: it can be found in the cloud, at the edge of the cloud, in the premises (on the customer edge) and even on your device. It will likely pop up where there are radio masts (very small) or regional data centres (very large). It will be telco-owned and operated (profitable for telcos) and third party neutral (not so much).

It the face of all this diversity and cross current activity, ETSI has adopted a stage-by-stage approach to keep pace with the industry as requirements become clearer, while at the same time not getting ahead and so acting as a cramp.

The just announced Phase 2 specifications encompass ETSI GS MEC 002, which includes new requirements for Phase 2, ETSI GS MEC 003, which tackles architecture and frameworks, and  ETSI GS MEC 009 which outlines general principles for service APIs.

  • ETSI GS MEC 002 defines the requirements for Multi-access Edge Computing with the aim of promoting interoperability and deployments. It focuses on NFV alignment since multi-access edge computing uses a virtualization platform for running applications at the mobile network edge. The specification also describes example use cases and their technical benefits, for the purpose of deriving requirements.
  • ETSI GS MEC 003 addresses the implementation of MEC applications as software-only entities that run on top of a virtualization infrastructure, which is located in or close to the network edge. A key new aspect of the Phase 2 version of this specification is the addition of MEC-in-NFV reference architecture, which defines how MEC-compliant edge deployments can be part of an overall NFV cloud architecture.
  • ETSI GS MEC 009  outlines general principles for service APIs.

APIs and cloud resource are key to edge development according to many, including Jason Hoffman, CEO of MobiledgeX, which is creating an ecosystem of mobile edge resources and services that will connect developers with CSPs to power next-generation apps and devices, he claims. Speaking with TelecomTV at MWC, Hoffman said he sees an emerging collection of developers in the AR, MR Computer Vision and Machine Learning area and “those applications need an edge between all the devices and a cloud,” he says.―Telecom TV
