History of MEF
Founded in 2001, MEF began as the Metro Ethernet Forum, aiming to accelerate the adoption of Carrier Ethernet globally. Over the years, MEF expanded its focus beyond Ethernet to include a broader spectrum of services such as SD-WAN, SASE, and automated lifecycle service orchestration. This evolution led to the rebranding as simply “MEF.”
One of MEF’s most significant contributions is the development of MEF 3.0, a framework that enables dynamic, assured, and orchestrated services across automated networks. MEF has built a reputation for collaborating with industry leaders like Cisco, Juniper Networks, AT&T, and Verizon to ensure global service compatibility.
With over 200 member companies worldwide, MEF continues to drive innovation through open APIs, reference implementations, and certification programs, making it a cornerstone in today’s network transformation landscape.
Recent Trends of MEF
MEF continues to lead the way in enabling automated, secure, and cloud-ready networks. One of the most talked-about trends is the expansion of MEF 3.0 to support SASE (Secure Access Service Edge), bridging security and networking at the edge. MEF is also advancing LSO (Lifecycle Service Orchestration) APIs to streamline multi-vendor service automation, a critical capability in modern cloud-native architectures.
The organization is increasingly focused on Zero Trust frameworks and AI-driven networking to meet the demands of cybersecurity and performance assurance. MEF has also introduced updated certification programs in SD-WAN, SASE, and Carrier Ethernet, catering to the rising demand for hybrid workforce solutions and cloud services.
With these developments, MEF is helping both service providers and enterprises achieve faster service deployment, better quality of experience, and end-to-end automation, reinforcing its role as a key influencer in networking and cloud transformation.
