802.1aj - Two-port MAC Relay
The full title of this PAR is "Standard for Local and Metropolitan Area Networks - Virtual Bridged Local Area Networks - Amendment 08: Two-port Media Access Control (MAC) Relay".
This standard specifies the function of a MAC Relay with two MACs, and the protocols and procedures to support its
operation. A MAC Relay is transparent to all frame-based media independent protocols except those explicitly addressed
to this device. It is remotely manageable through at least one of its external MACs, and signals a failure of either MAC's
LAN through the other MAC.
The wide and growing deployment of Ethernet Provider Services has created a demand for simple two-port demarcation
devices that connect two 802 media or 802 media emulations. The lack of standards for such devices, and particularly for
link-loss signalling and remote diagnosis, is impeding the growth of this industry. This standard will greatly improve this
situation.
Public networks represent a new and very broad application space for IEEE 802 technologies and specifically for
Provider Bridges (P802.1ad) and Ethernet in the First Mile (802.3ah). Numerous vendors and potential users (the Service
Providers) have expressed the need to integrate Ethernet link technologies with their existing infrastructure at a low cost,
while providing the manageability and remote diagnostic capabilities traditionally offered by circuit switched
technologies.
