Remember SLIP and PPP? These two protocols tunnel IP packets through
RS-232 serial connections.

If you have DSL or FiOS then your Internet service is probably PPPoE: IP
encapsulated in PPP encapsulated in Ethernet then encoded for the copper
or fiber loop.

Encapsulating protocols within protocols isn't difficult and it isn't
expensive. DSL uses PPPoE for these two reasons, and FiOS continues to
use it for the same reasons. If a given implementation incurs excessive
overhead or latency then it's the implementation's fault, not the idea
of it.

I suggest circa 1998.
