14 | B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is |
15 | a routing protocol for multi-hop ad-hoc mesh networks. The | |
16 | networks may be wired or wireless. See | |
17 | https://www.open-mesh.org/ for more information and user space | |
18 | tools. | |

24 | help |
25 | This option enables the B.A.T.M.A.N. V protocol, the successor | |
26 | of the currently used B.A.T.M.A.N. IV protocol. The main | |
27 | changes include splitting of the OGM protocol into a neighbor | |
28 | discovery protocol (Echo Location Protocol, ELP) and a new OGM | |
29 | Protocol OGMv2 for flooding protocol information through the | |
30 | network, as well as a throughput based metric. | |
31 | B.A.T.M.A.N. V is currently considered experimental and not | |
32 | compatible to B.A.T.M.A.N. IV networks. | |

40 | This option enables BLA (Bridge Loop Avoidance), a mechanism | |
41 | to avoid Ethernet frames looping when mesh nodes are connected | |
42 | to both the same LAN and the same mesh. If you will never use | |
43 | more than one mesh node in the same LAN, you can safely remove | |
44 | this feature and save some space. | |

51 | This option enables DAT (Distributed ARP Table), a DHT based | |
52 | mechanism that increases ARP reliability on sparse wireless | |
53 | mesh networks. If you think that your network does not need | |
54 | this option you can safely remove it and save some space. | |

d353d8d4 MH |
59 | help |
60 | This option enables network coding, a mechanism that aims to | |
61 | increase the overall network throughput by fusing multiple | |
62 | packets in one transmission. | |
63 | Note that interfaces controlled by batman-adv must be manually | |
64 | configured to have promiscuous mode enabled in order to make | |
65 | network coding work. | |
66 | If you think that your network does not need this feature you | |
67 | can safely disable it and save some space. | |
