Linux bondng & Wireless

[zASSAz]

Есть идея использовать 2 вифи бриджа с каждой стороны на разных каналах и Linux бондинг драйвер - для увеличения ширины канала. Как я понял это типа транка получается.

 

Может кто уже пробовал? какие идеи?

Не совсем. Интересно какой из этих режимов будет работать с ВиФИ.

И что более предпочтительнее.

------------------------------------------------------

balance-rr or 0

 

Round-robin policy: Transmit in a sequential order

from the first available slave through the last. This

mode provides load balancing and fault tolerance.

 

active-backup or 1

 

Active-backup policy: Only one slave in the bond is

active. A different slave becomes active if, and only

if, the active slave fails. The bond's MAC address is

externally visible on only one port (network adapter)

to avoid confusing the switch. This mode provides

fault tolerance.

 

balance-xor or 2

 

XOR policy: Transmit based on [(source MAC address

XOR'd with destination MAC address) modula slave

count]. This selects the same slave for each

destination MAC address. This mode provides load

balancing and fault tolerance.

 

broadcast or 3

 

Broadcast policy: transmits everything on all slave

interfaces. This mode provides fault tolerance.

 

802.3ad or 4

 

IEEE 802.3ad Dynamic link aggregation. Creates aggregation

groups that share the same speed and duplex settings.

Transmits and receives on all slaves in the active

aggregator.

 

balance-tlb or 5

 

Adaptive transmit load balancing: channel bonding that does

not require any special switch support. The outgoing

traffic is distributed according to the current load

(computed relative to the speed) on each slave. Incoming

traffic is received by the current slave. If the receiving

slave fails, another slave takes over the MAC address of

the failed receiving slave.

 

balance-alb or 6

 

Adaptive load balancing: includes balance-tlb + receive

load balancing (rlb) for IPV4 traffic and does not require

any special switch support. The receive load balancing is

achieved by ARP negotiation. The bonding driver intercepts

the ARP Replies sent by the server on their way out and

overwrites the src hw address with the unique hw address of

one of the slaves in the bond such that different clients

use different hw addresses for the server.

 

Receive traffic from connections created by the server is

also balanced. When the server sends an ARP Request the

bonding driver copies and saves the client's IP information

from the ARP. When the ARP Reply arrives from the client,

its hw address is retrieved and the bonding driver

initiates an ARP reply to this client assigning it to one

of the slaves in the bond. A problematic outcome of using

ARP negotiation for balancing is that each time that an ARP

request is broadcasted it uses the hw address of the

bond. Hence, clients learn the hw address of the bond and

the balancing of receive traffic collapses to the current

salve. This is handled by sending updates (ARP Replies) to

all the clients with their assigned hw address such that

the traffic is redistributed. Receive traffic is also

redistributed when a new slave is added to the bond and

when an inactive slave is re-activated. The receive load is

distributed sequentially (round robin) among the group of

highest speed slaves in the bond.

 

When a link is reconnected or a new slave joins the bond

the receive traffic is redistributed among all active

slaves in the bond by intiating ARP Replies with the

selected mac address to each of the clients. The updelay

modeprobe parameter must be set to a value equal or greater

than the switch's forwarding delay so that the ARP Replies

sent to the clients will not be blocked by the switch.

balance-xor or 2

Этот режим уж точно будет работать :)

zASSAz если удастся поставить эксперемент, то сообщи сюда результаты, если не затруднит. Сам собираюсь такое проделать.

OK. На днях обещали еще два AP принести ...вот и буду пробовать...

Ещё как вариант можно попробовать очередь TEQL.
