ATM is a high-speed networking technology for Local Area Networks
|
|
|
|
|
and Wide Area Networks. It uses a fixed packet size and is
|
|
|
|
|
connection oriented, allowing for the negotiation of minimum
|
|
|
|
|
bandwidth requirements.
|
|
|
|
|
|
|
|
|
|
In order to participate in an ATM network, your Linux box needs an
|
|
|
|
|
ATM networking card. If you have that, say Y here and to the driver
|
|
|
|
|
of your ATM card below.
|
|
|
|
|
|
|
|
|
|
Note that you need a set of user-space programs to actually make use
|
2020-04-27 22:01:21 +00:00

|
|
of ATM. See the file <file:Documentation/networking/atm.rst> for

Normally, an "ICMP host unreachable" message is sent if a neighbour
|
|
|
|
|
cannot be reached because there is no VC to it in the kernel's
|
|
|
|
|
ATMARP table. This may cause problems when ATMARP table entries are
|
|
|
|
|
briefly removed during revalidation. If you say Y here, packets to
|
|
|
|
|
such neighbours are silently discarded instead.

This device will act like an ethernet from the kernels point of view,

with the traffic being carried by ATM PVCs (currently 1 PVC/device).
