In the Communication Service Provider (CSP) industry today, there are many confusions with terms. One such example is Metro Ethernet (ME) and Carrier Ethernet (CE). Many people have asked me the difference between the two. Therefore, I just though of writing this small blog, just to clarify the doubts.
ME was 1st
to come. Hence the Metro Ethernet Forum (MEF). Carrier Ethernet (CE) came later
and MEF adopted it as well. So, MEF the one defines the generic standards for
ME and now CE.
Both ME and CE, though technical
terms, are used as commercial words these days by vendors.
ME is a service. CE can provide
ME services too. ME and CE demarcation is now becoming blurred and the future
term will be CE.
In fact CE and ME refers to the
same thing, i.e well known Ethernet technology/interface used in the
Local Area Network (LAN) being used in the Metropolitan Area Network (MAN) and Wide Area Network (WAN) with hardened capabilities, defined as 5 attribute by MEF.
