Which Service?

MEF service types below are defined to be simple port-based “private” services or VLAN-aware “virtual-private” services where the former is a single service is delivered at a single port called a User-to-Network Interface (UNI) and the latter enables multiple services to be delivered at a UNI.

  • E-Line (point-to-point service type)
    Provides the simplest form of connectivity and is the most popular service for providing Internet access and site-to-site connectivity.
    Services consist of Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL) for port-based and VLAN-aware services, respectively
  • E-LAN (multipoint-to-multipoint service type)
    Allows the Wide Area Network locations to appear as if they are connected to the in-house or campus Local Area Network.
    Services consist of Ethernet Private LAN (EP-LAN) and Ethernet Virtual Private LAN (EVP-LAN) for port-based and VLAN-aware services, respectively
  • E-Tree (rooted multipoint service type)
    Provides traffic segmentation ideal for applications where remote locations are required to communicate to a central location but not to each other such as multi-tenant cloud-based applications.
    Services consist of Ethernet Private Tree (EP-Tree) and Ethernet Virtual Private Tree (EVP-Tree) for port-based and VLAN-aware services, respectively
