9 | ATM is a high-speed networking technology for Local Area Networks |
| 10 | and Wide Area Networks. It uses a fixed packet size and is | |
| 11 | connection oriented, allowing for the negotiation of minimum | |
| 12 | bandwidth requirements. | |
| 13 | ||
| 14 | In order to participate in an ATM network, your Linux box needs an | |
| 15 | ATM networking card. If you have that, say Y here and to the driver | |
| 16 | of your ATM card below. | |
| 17 | ||
| 18 | Note that you need a set of user-space programs to actually make use | |
| ff2269f1 | 19 | of ATM. See the file <file:Documentation/networking/atm.rst> for |
| 6a2e9b73 SR |
20 | further details. |

| 26 | Classical IP over ATM for PVCs and SVCs, supporting InARP and | |
| 27 | ATMARP. If you want to communication with other IP hosts on your ATM | |
| 28 | network, you will typically either say Y here or to "LAN Emulation | |
| 29 | (LANE)" below. | |

| 34 | help | |
| 35 | Normally, an "ICMP host unreachable" message is sent if a neighbour | |
| 36 | cannot be reached because there is no VC to it in the kernel's | |
| 37 | ATMARP table. This may cause problems when ATMARP table entries are | |
| 38 | briefly removed during revalidation. If you say Y here, packets to | |
| 39 | such neighbours are silently discarded instead. | |

| 44 | help | |
| 45 | LAN Emulation emulates services of existing LANs across an ATM | |
| 46 | network. Besides operating as a normal ATM end station client, Linux | |
| 47 | LANE client can also act as an proxy client bridging packets between | |
| 48 | ELAN and Ethernet segments. You need LANE if you want to try MPOA. | |

| 53 | help | |
| 54 | Multi-Protocol Over ATM allows ATM edge devices such as routers, | |
| 55 | bridges and ATM attached hosts establish direct ATM VCs across | |
| 56 | subnetwork boundaries. These shortcut connections bypass routers | |
| 57 | enhancing overall network performance. | |

| 88e9fa8a | 63 | ATM PVCs can carry ethernet PDUs according to RFC2684 (formerly 1483) |
| 6a2e9b73 SR |
64 | This device will act like an ethernet from the kernels point of view, |
| 65 | with the traffic being carried by ATM PVCs (currently 1 PVC/device). | |
| 66 | This is sometimes used over DSL lines. If in doubt, say N. | |

| 74 | you know what you are doing. |
