Course Overview

The course deals with the different aspects of the work being done by the Metro Ethernet Forum. We will present the key technical agreements published by MEF. The different Ethernet services and UNI types defined by MEF will be described in detail. Among other issues traffic management, service protection and OAM capabilities will be presented. We conclude by presenting the testing procedures defined by MEF to certify compliant equipment.

Who should attend?

The seminar is built for Technical, Marketing and Business Development individuals from Telecom Service Providers as well as Manufacturers of Ethernet or Metro Ethernet equipment.

Prerequisite:

Basic knowledge of data communications and Ethernet is expected from the participants.
