Metro Ethernet
Metro Ethernet is an Ethernet transport network that provides point-to-point or multipoint connectivity services over a metropolitan area network (MAN). Ethernet originated as a LAN technology, and became a replacement for low-speed WAN technologies. BTC Metro is based on Multi-protocol label switching (MPLS) Technology, this technology enables faster delivery of data across the Metro network using labeled data packets.
This is a a point to point metro connection between two or more sites such as Data Centres. This connection can support speeds from 1M to 10G, 40G & 100G to be supported in future
Metro Ethernet connection options
E-LINE: Normally referred to as Point to Point connection, connects point “A” to Point “B”.
E-LAN: Normally referred to as Multipoint to Multipoint connection, each site communicates to another without going through the HQ.
ETREE: Normally referred to as Hub and Spoke, all services have to pass through the HQ before going to final destination.
MPLS Layer 3 VPN: uses a peer-to-peer model through a Border Gateway Protocol (BGP) to distribute VPN-related information. Routing information is outsourced to service providers.

Remote site connectivity to data centers
- Enterprises often require connectivity from their remote sites to one or more Data Centers.
- Connect Core DC to remote DC’s
- Data mirroring, replication or backups
- Connect distributed LAN’s
- Network resource sharing
- High speed connectivity
- Network redundancy
- Service convergence
- Network resiliency
- Guaranteed QoS
- Government & Corporates
- EVC can connect a number of sites in a tree format
- One or more roots can transmit data to a number of leaves
- Root to Leaf communication provided intrinsically by the network
- Enterprise can define number of roots and leaves as well as bandwidth assigned to each
- Independent streams can be configured between the same set of sites in order to segregate traffic
