Ethernet Bridging
by Norman Finn
No standards organization owns the term Ethernet. But if you had to define Ethernet,
you would do well to start with the definition of the services offered by a wired or wireless
network, including bridges, as defined by the Institute of Electrical and Electronic
Engineers Standards Association LAN/MAN Standards Committee, or IEEE 802. This
starting point is merited by the ubiquity of IEEE 802-compliant equipment. Practically
any protocol or service that can utilize an Ethernet link of any type can also utilize a
bridged network of Ethernet devices.
The simplest and most straightforward way to deliver Ethernet services to customers
is to use established Ethernet equipment and services, rather than ???Ethernet over
xyz,??? where xyz can be SONET, MPLS, ATM, or any other technology.
