2 # Asynchronous Transfer Mode (ATM)
6 tristate "Asynchronous Transfer Mode (ATM)"
8 ATM is a high-speed networking technology for Local Area Networks
9 and Wide Area Networks. It uses a fixed packet size and is
10 connection oriented, allowing for the negotiation of minimum
11 bandwidth requirements.
13 In order to participate in an ATM network, your Linux box needs an
14 ATM networking card. If you have that, say Y here and to the driver
15 of your ATM card below.
17 Note that you need a set of user-space programs to actually make use
18 of ATM. See the file <file:Documentation/networking/atm.txt> for
22 tristate "Classical IP over ATM"
23 depends on ATM && INET
25 Classical IP over ATM for PVCs and SVCs, supporting InARP and
26 ATMARP. If you want to communication with other IP hosts on your ATM
27 network, you will typically either say Y here or to "LAN Emulation
30 config ATM_CLIP_NO_ICMP
31 bool "Do NOT send ICMP if no neighbour"
34 Normally, an "ICMP host unreachable" message is sent if a neighbour
35 cannot be reached because there is no VC to it in the kernel's
36 ATMARP table. This may cause problems when ATMARP table entries are
37 briefly removed during revalidation. If you say Y here, packets to
38 such neighbours are silently discarded instead.
41 tristate "LAN Emulation (LANE) support"
44 LAN Emulation emulates services of existing LANs across an ATM
45 network. Besides operating as a normal ATM end station client, Linux
46 LANE client can also act as an proxy client bridging packets between
47 ELAN and Ethernet segments. You need LANE if you want to try MPOA.
50 tristate "Multi-Protocol Over ATM (MPOA) support"
51 depends on ATM && INET && ATM_LANE!=n
53 Multi-Protocol Over ATM allows ATM edge devices such as routers,
54 bridges and ATM attached hosts establish direct ATM VCs across
55 subnetwork boundaries. These shortcut connections bypass routers
56 enhancing overall network performance.
59 tristate "RFC1483/2684 Bridged protocols"
60 depends on ATM && INET
62 ATM PVCs can carry ethernet PDUs according to RFC2684 (formerly 1483)
63 This device will act like an ethernet from the kernels point of view,
64 with the traffic being carried by ATM PVCs (currently 1 PVC/device).
65 This is sometimes used over DSL lines. If in doubt, say N.
67 config ATM_BR2684_IPFILTER
68 bool "Per-VC IP filter kludge"
71 This is an experimental mechanism for users who need to terminate a
72 large number of IP-only vcc's. Do not enable this unless you are sure
73 you know what you are doing.
