As mobile and Internet of Things data mounts up, it is increasingly important to process as much as possible close to the edge of the network, to avoid impossible strain on the connections to the cloud, with resulting outages and high latency. Vendors are racing to drive and define the way edge computing will be done, with the Open Fog consortium (based around Cisco’s fog concepts) and ETSI’s MEC (Multi-access – formerly Mobile – Edge Computing), leading the field. ZTE is trying to go one better than its rivals in driving a unified framework for the mobile edge, by combining fog and MEC ideas in a system architecture which it dubs ‘Cloud-Fog Collaboration’. This architecture “unifies the concepts of fog…
