Question 10

What is E-Access

Answer 10

OVC-Based Services
In the beginning of 2010, the MEF started defining a new service type called E-Access, used to categorize new OVC-based service definitions. These service definitions utilize a P2P OVC with one UNI endpoint and one ENNI endpoint. There are port-based and VLAN-based E-Access service definitions under development in the MEF. Their names are listed in Figure 20.
Figure 20: OVC-based Ethernet Services
E-Access service types are typically used by wholesale Ethernet access providers who sell their services to retail Ethernet service providers who are delivering an EVC-based service to their end-user subscribers.
Access EPL, formerly known as E-APL, is similar to EPL where it supports a single OVC-based service instance at the UNI. Access EPL and EPL
are port-based services. However, an Access EPL supports a service multiplexed ENNI at the other endpoint of the OVC, versus a UNI for an EPL. Access EPL is the simplest form of OVC-based service because it requires no VLAN-awareness at the UNI. This eliminates any customer VLAN ID mapping coordination between the wholesale Ethernet access provider who delivers the Access EPL and the retail Ethernet service provider peering with the Ethernet access provider at the ENNI.
