DC-Net's Ethernet service, delivered over an all-fiber network that spans across the District, offers point-to-point and point-to-multipoint transport with speeds ranging from 10 Mbps to 10 Gbps. The network is built with redundancy and services are optically protected over multiple fiber rings providing sub-50ms failover for any transport in the network core. Our Ethernet data service supports both copper and fiber hand-offs, single and multimode.

Standardized Metro Ethernet Forum (MEF) services include:

• E-Line services—E-Line includes both Ethernet Virtual Private Line (EVPL) and Ethernet Private Line (EPL) services. E-Line supports full port speeds (10 Mbps, 100 Mbps, 1 Gbps, and 10 Gbps) and can support different quality of service (QoS) priorities for customer traffic. E-Line is a point-to-point configuration that can be provisioned as a Layer 1 service over the Wave Division Multiplexed (WDM) ring or as a Layer 2 tunnel providing a transparent dedicated connection between two sites.
• Ethernet LAN (E-LAN) services—E-LAN is a point-to-multipoint Ethernet service connecting three or more sites and provisioned over Layer 2 tunnels. It supports full port speeds (10 Mbps, 100 Mbps, 1 Gbps, and 10 Gbps) and can support different QoS priorities for customer traffic.
• E-Tree services—E-Tree is a multipoint-to-multipoint Ethernet service connecting several sites. More than one site can be configured as the root site and other sites can communicate with each other through multiple root sites. E-Tree supports full port speeds (10 Mbps, 100 Mbps, 1 Gbps, and 10 Gbps) and can support different QoS priorities for customer traffic.

Up to seven QoS priority levels are available on this service. Priority can be set for traffic on each E-LAN port such as real-time voice or video traffic, which can get a higher priority than standard data traffic. Public and private peering points for interconnection and offsite data storage/recovery are available.
