A Network Experts contribution on MEF Foundational elements

Having associated with MEF (then Metro Ethernet Forum) from as far back as 2003, I thought of sharing a bit about my experience with MEF for the benefit of everyone.

Few months after joining my current company (a Service Provider in Sri Lanka) as a young Engineer back in 2003, I was asked to plan and design a network using a technology called “Metro Ethernet”. Though I had heard about Ethernet, Metro Ethernet was kind of new to me. I searched on the web and within the 1st few search results there came the “Metro Ethernet Forum”.

While referring to other learning material, I extensively used the material available in MEF to learn about the foundation principles of Metro Ethernet. I found the MEF Technical Specifications extremely user friendly, compared to the documents published by other SDOs (Standards Developing Organizations). That made me to read more MEF documents. I also used the book Metro Ethernet by Sam Halabi. Having gained enough knowledge, in 2004, I started architecting, planning and designing Sri Lanka’s 1st Metro Ethernet Network from scratch and prepared the RFP (Request For Proposal) documents for product selection. The document approach and evolution was based on various IETF (RFCs and drafts), ITU-T, IEEE and MEF specifications. Two of the MEF specifications included in the RFP were MEF 8: Implementation Agreement for the Emulation of PDH Circuits over Metro Ethernet Network and MEF 14: Abstract Test Suite for Traffic Management Phase 1.

As we wanted to have CESoPSN (Circuit Emulation Services over Packet Switched Networks), MEF 8 was included.
