Ethernet Local Area Network Overview


Technical Specifications for Ethernet Local Area Network (ELAN)

Built on industry-standard, MEF-compliant Ethernet, ELAN connects multiple locations over a secure multipoint-to-multipoint connection with scalable bandwidth speeds ranging from 5 Mbps to 10 Gbps. ELAN allows customers to connect their business locations at native LAN speeds with Ethernet interfaces of 10Mbps, 100 Mbps,1 Gbps up to 10 Gbps.

ELAN Specifications

  • Ethernet User-to-Network Interface: ELAN provides bidirectional, full duplex transmission of Ethernet frames using a standard IEEE 802.3 Ethernet interface (UNI).

  • Service Multiplexing: the hub site can have all remote site EVCs multiplexed on a single UNI, eliminating the need for multiple ports on the customer’s router or Ethernet switch.

  • Maximum frame size: ELAN supports a Maximum Transmission Unit (MTU) packet size of 1600 bytes to support untagged or 802.1Q tagged packet sizes. Jumbo packets can be considered on an individual case basis.

  • VLAN tag preservation: ELAN supports IEEE 802.1Q VLAN-tagged customer frames.

  • Standard number of EVCs per UNI: up to 20 are included with more available at an additional charge.

  • Standard number of VLAN IDs per EVC: up to 20 are included with more available at an additional charge.

  • Ethernet Service Frame Disposition: All frames are delivered conditionally through the network based on which EVCs they are sent to as specified in the VLAN ID to EVC map provided by the customer.

  • Layer 2 Control Protocol (L2CP) Processing: L2CP frames are either discarded at the UNI, tunneled across the network or processed by the UNI.
