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

31 | config ATM_CLIP_NO_ICMP | |
32 | bool "Do NOT send ICMP if no neighbour (EXPERIMENTAL)" | |
33 | depends on ATM_CLIP | |
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. | |

41 | config ATM_LANE | |

43 | depends on ATM | |
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. | |

50 | config ATM_MPOA | |
51 | tristate "Multi-Protocol Over ATM (MPOA) support (EXPERIMENTAL)" | |
52 | depends on ATM && INET && ATM_LANE!=n | |
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. | |

71 | help | |
88e9fa8a | 72 | This is an experimental mechanism for users who need to terminate a |
6a2e9b73 SR |
73 | large number of IP-only vcc's. Do not enable this unless you are sure |
74 | you know what you are doing. |
