Standardized Services
The standardized services attribute requires support for Ethernet services and also
for other prevailing services, notably TDM-based services over a Carrier Ethernet infrastructure
(i.e., over an E-LINE/E-LAN service). There has been considerable effort
spent on standardizing Ethernet services (as detailed in the previous section) in MEF
6 that encompassed setting up bandwidth profiles and traffic management. Major developments
are outlined in Table 2.2.
Supporting other services, especially the TDM-based services, has also been addressed
quite significantly by the MEF (and other bodies) and a reasonably detailed
overview is provided next.

Circuit Emulation Services over Ethernet (CESoE) As noted previously, non packet services
such as PDH and SONET/SDH account for a significant amount of customer demand in
the market today, and Service Providers expect to leverage this opportunity.
