ABSTRACT
This chapter introduces the European Telecommunications Standards Institute (ETSI) multi-access edge (ME) computing (MEC) standard, and the related components and main technology enablers. It provides an overview of the MEC services scenarios, in order to offer the reader a comprehensive set of suitable use cases enabled by MEC. Looking further into the ME Platform, we note a number of functionalities that ETSI MEC does assume to be present there, notably “traffic rules control” function, “DNS handling” function, and a “service registry” function. ETSI MEC recognizes this issue and enables a management framework that splits the management functions between a decentralized component that is present at every ME host and a centralized component present in the ME system. The presence at an MEC site of a very simple application component, one with a low computational footprint, can often make a huge difference to the overall application performance.
