What is Metro Ethernet (MetroE)?
Metro Ethernet is a type of network that provides point to point or multi-point connections over a MAN (metropolitan area network). The maximum throughput for this network is 10gbps.
The disadvantages consist of latency, small upload speeds and high packet loss.
Metro Ethernet Forum (MEF) is an organization which is a non-profit that seeks to accelerate the use of carrier class Ethernet networks and services worldwide. This organization is made up of leading service providers, local exchange carriers, test equipment vendors, network equipment vendors and other networking companies which share an interest in the organization's goal.
Metro Ethernet Forum basically provides two types of certifications which are as follows −
