Virtual LAN services

Overview

The Virtual LAN (VLAN) Service application provides a packet-based Ethernet connection via a shared packet over SONET connection.

Description

VLAN Service applications can be utilized by multiple customers over a shared ring for improved bandwidth efficiency. Alcatel-Lucent 1665 DMX uses VLANs and allows bandwidth to be shared among customers. Up to 4093 VLANs can be assigned to guarantee privacy among various customers.

Multiple customers can use the VLAN interconnect (multipoint LAN) capability of Alcatel-Lucent 1665 DMX at multiple sites.

The figure below shows Alcatel-Lucent 1665 DMX's varied VLAN capabilities.

Application advantage

Alcatel-Lucent 1665 DMX Ethernet services extend packet switching from the LAN to the WAN. In doing so, enterprise interconnect locations in metropolitan areas can transport traffic much more efficiently over shared and/or provisionable access bandwidth. ISP carrier access applications can use spanning tree protection and flexible bandwidth allocation (using STS-1 virtual concatenation) in the WAN.
