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

Classical IP over ATM for PVCs and SVCs, supporting InARP and
|
|
ATMARP. If you want to communication with other IP hosts on your ATM
|
|
network, you will typically either say Y here or to "LAN Emulation
|
|
(LANE)" below.

help
|
|
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.

LAN Emulation emulates services of existing LANs across an ATM
|
|
network. Besides operating as a normal ATM end station client, Linux
|
|
LANE client can also act as an proxy client bridging packets between
|
|
ELAN and Ethernet segments. You need LANE if you want to try MPOA.

Multi-Protocol Over ATM allows ATM edge devices such as routers,
|
|
bridges and ATM attached hosts establish direct ATM VCs across
|
|
subnetwork boundaries. These shortcut connections bypass routers
|
|
enhancing overall network performance.

ATM PVCs can carry ethernet PDUs according to RFC2684 (formerly 1483)
|
|
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).
|
|
This is sometimes used over DSL lines. If in doubt, say N.

This is an experimental mechanism for users who need to terminate a
|
|
large number of IP-only vcc's. Do not enable this unless you are sure
|
|
you know what you are doing.
