Transparent LAN Service
Encyclopedia
Transparent LAN Service is a service from a carrier
linking together remote Ethernet
networks. It is called "transparent" because the connected networks are viewed as one contiguous network by the customer, regardless of the deployed technology by the carrier in between. Its primary real world deployment is usually limited to corporations who 1) require remote office or back-end data center
connectivity at close to LAN
speed, and 2) do not have in-house expertise in WAN
management, as TLS is usually purchased as a fully managed service (meaning the carrier chosen owns, configures, monitors, and maintains the equipment needed for the service to function). The availability of TLS service depends on the carrier's underlying network architecture. In most cases, it is only available in large metropolitan areas and office buildings, campuses, or data centers large enough to warrant the proper equipment.
Transparent LAN
service between two sites has been successful, but multipoint transparent LANs have been problematic due to the difference in architecture between the broadcast-based Ethernet and the carrier's point-to-point network. The VPLS (a type of VPN) standard was developed to resolve the problem using IP
and MPLS
routers.
