Custom AutoNegotiation Advertisement (CANA)
An enhancement of the IEEE 802.3
autonegotiation process on the 10/100/1000
copper ports. CANA offers improved control
over the autonegotiation process. The
system advertises all port capabilities that for
tri-speed ports include 10 Mb/s, 100 Mb/s,
1000 Mb/s speeds and duplex and half-duplex
modes of operation. This advertisement
results in autonegotiation between the local
and remote end that settles on the highest
common denominator. CANA can advertise a
user-defined subset of the capabilities that settle
on a lower or particular capability.
customer edge (CE)
A router or switch located at a customer site that
connects to a provider edge (PE) router.
customer premise equipment (CPE)
Equipment or inside wiring at the customer site
that connects to telecommunications equipment.
cyclic redundancy check (CRC)
Ensures frame integrity is maintained during
transmission. The CRS performs a computation
on frame contents before transmission and
on the receiving device. The system discards
frames that do not pass the CRC.
