  The emergence of Multi-Access Edge Computing (MEC) technology aims at
extending cloud computing capabilities to the edge of the wireless access
networks. MEC provides real-time, high-bandwidth, low-latency access to radio
network resources, allowing operators to open their networks to a new ecosystem
and value chain. Moreover, it will provide a new insight to the design of
future 5th Generation (5G) wireless systems. This paper describes five key
technologies, including Network Function Vitalization (NFV), Software Defined
Networking (SDN), Network Slicing, Information Centric Networking (ICN) and
Internet of Things (IoT), that intensify the widespread of MEC and its
adoption. Our goal is to provide the associativity between MEC and these five
driving technologies in 5G context while identifying the open challenges,
future directions, and tangible integration paths.
