Concept
Multi-access edge computing
Summary
Multi-access edge computing (MEC), formerly mobile edge computing, is an ETSI-defined network architecture concept that enables cloud computing capabilities and an IT service environment at the edge of the cellular network and, more in general at the edge of any network. The basic idea behind MEC is that by running applications and performing related processing tasks closer to the cellular customer, network congestion is reduced and applications perform better. MEC technology is designed to be implemented at the cellular base stations or other edge nodes, and enables flexible and rapid deployment of new applications and services for customers. Combining elements of information technology and telecommunications networking, MEC also allows cellular operators to open their radio access network (RAN) to authorized third parties, such as application developers and content providers.
Technical standards for MEC are being developed by the European Telecommunications Standards Institute, which has produced a technical white paper about the concept.
MEC provides a distributed computing environment for application and service hosting. It also has the ability to store and process content close to cellular subscribers, for faster response time. Applications can also be exposed to real-time radio access network (RAN) information.
The key element is the MEC application server, which is integrated at the RAN element. This server provides computing resources, storage capacity, connectivity and access to RAN information. It supports a multitenancy run-time and hosting environment for applications. The virtual appliance applications are delivered as packaged operating system virtual machine (VM) images or containers incorporating operating systems and applications. The platform also provides a set of middleware application and infrastructure services. Application software can be provided from equipment vendors, service providers and third-parties.
