The OpenFog Consortium and ETSI have signed a memorandum of understanding to collaborate on fog-enabled mobile edge applications and technologies. Their partnership aims to support organizations developing 5G, mission-critical, and data-intensive applications by advancing fog computing and networking, and by reducing duplicated technical effort across related domains.
Collaboration between OpenFog and ETSI MEC
The OpenFog Consortium will work directly with the ETSI Multi-access Edge Computing (MEC) Industry Specification Group (ISG). Together, they will align on information and communication technology (ICT) standardization and interoperability needs, sharing relevant technical work in progress to ensure complementary outcomes.
ETSI MEC focuses on multi-access edge hosts deployed across different operator networks that run edge applications in a coordinated way. The OpenFog Reference Architecture complements this by enabling interoperability across operators through a physical and logical multi-layered hierarchy of cooperating fog nodes that bridge the cloud and the network edge. This combined approach promotes a cohesive edge ecosystem in which edge services can be deployed and consumed consistently across diverse infrastructures.
API Interoperability as the First Priority
The initial joint initiative will center on application programming interfaces (APIs) that enable edge computing interoperability. ETSI’s current package of MEC APIs contains features and patterns that can be adapted and incorporated into the OpenFog Reference Architecture. In particular, ETSI MEC specifies an API framework to support delivery of services to locally hosted or remotely authorized applications, which aligns with fog computing’s need to manage distributed services and data flows near the edge.
Market Components and Opportunities
The fog computing market can be described in two main segments: hardware and software. Hardware components include servers, routers, switches, gateways, and controllers deployed at the edge. Software consists of custom application code and fog computing platform elements that orchestrate services, manage data, and enforce policies.
Software typically generates the majority of market revenue due to lower capital requirements and higher recurring value through licenses, subscriptions, and managed services. Fog software enables use cases across building and home automation, smart energy management, connected health solutions, and smart manufacturing, among others. By processing data closer to where it is generated, fog architectures reduce latency, conserve bandwidth, enhance privacy, and provide resilient local processing for mission-critical workloads.
Benefits of Alignment and Standardization
By aligning ETSI MEC specifications with the OpenFog Reference Architecture, the collaboration seeks to create consistent interoperability models, common API semantics, and shared operational practices. Standardized APIs and interfaces help application developers, equipment vendors, and service providers accelerate deployment, reduce integration costs, and ensure predictable behavior across multi-operator and multi-vendor environments.
Standardization also helps avoid fragmentation in a rapidly evolving edge ecosystem. When organizations adopt compatible frameworks for service discovery, lifecycle management, and resource orchestration, they can focus on delivering differentiated applications and services—such as low-latency analytics, localized AI inference, and secure data handling—without reinventing foundational connectivity and management mechanisms.
Outlook
The joint work of the OpenFog Consortium and ETSI MEC ISG represents a practical step toward a unified edge computing landscape that supports 5G-era requirements and data-dense applications. By prioritizing API interoperability and sharing technical expertise, the two organizations are positioned to help the industry evolve toward interoperable, efficient, and secure fog and edge deployments that serve diverse verticals.
