Table 1 Comparative analysis fog orchestrator architectures

From: Fog orchestration for the Internet of Everything: state-of-the-art and research challenges

Challenges SORTS SOAFI ETSI IGS MEC CONCERT
Scheduling Planner mechanisms schedule processes and their locations Service management and catalog done by the Orchestrator Planning, deployment and management carried out by the MEO LCM implements scheduling strategies, services deployed using a SDN approach
Path Computation N/A N/A Indicated as needed but no further details provided N/A
Discovery and Allocation Service discovery mechanisms at the Orchestrator to enable lookup Handled by infrastructure manager Indicated as needed but no further details provided Orchestrate physical resources into virtual ones, carried out by the Conductor
Interoperability N/A M2M interoperability through standard communication N/A N/A
Latency Service placement mechanisms at the Orchestrator to minimize latency N/A N/A Provide local servers at the Fog to minimize latency
Resilience Survivability mechanisms at the Resource Manager N/A N/A Use of resilience metrics for scheduling purposes
Prediction and Optimization Global mechanisms to improve performance of the system Set of policies for virtual environments Indicated as needed but no further details provided State of the network used for optimization mechanisms
Security and Privacy Security manager provides different privacy mechanisms Data security mechanisms as dependencies of the Orchestrator N/A N/A
Authentication, Access, and Account Authentication mechanisms supported by its security manager N/A Indicated as needed but no further details provided N/A
