You'll likely want something of a higher quality.  But it can be done.

I think that wisps that don't have a backup offering are missing a very

A little feedback from the collective is appreciated here. I have a high 
school who has bought a connection from me but is also stuck with an old T1 
circuit under contract for the next 3 years. They want both connections to 
be used all the time and for all traffic to automatically go through the 
working connection if one fails. Basically they want load balancing and 
failover. All addresses are nat'd private space IPs.  I would think I 
should be able to do this with Mikrotik and/or Star OS but I do not know 
how. Your thoughts  and or other suggestions are highly appreciated. If 
only failover or only load balance is possible then suggestions on that are 
welcome also. By the way, the T1 provider is not me and will likely not 
work with me unfortunately. We have to leave their network settings intact.

Re: [WISPA] Redundant Connections

2006-01-13 Thread Tom DeReggi
Have you used that backhaul to carry one of your high end business client's 
cisco VPNs?
Most people don't even know how to detect that packets are getting sent out 
of order, and don't realize bandwidth is being wasted on packet drops.
The reason is the only way to know is to go into the logs of the end user's 
VPN routers. Cisco VPN gear has some good tools to test the VPN and report 
the loss. It was the tech company of the subscriber, that it brought it to 
our attention and noticed it.  And on $500 a month ARPU subs, if they see 
something like that, it means cancellation, if it can't be resolved. The 
reason is high end customers shoot for 100% not 99.9%. Andwhen things aren't 
perfect, the smarter techs realize that a less than perfect link could 
effect many different things that get troubleshooted over time, so the goal 
is to make it perfect to rule it out from ever being a factor. If fiber can 
make it perfect and wireless can't, wireless goes. That has been my 
experience.


So my question to you is... when you use Mikrotik for Per Packet load 
balancing, does the Mikrotik, just guarantee that the packets arrive in 
order, or does the Mikrotik correct any errors in the packets getting 
received out of order, or are your links lucky to just be capable of 
delivering the packets in order? Technically, if a radio has a buffer or 
queue, its possible for the protocols to re-order the packets so they are 
back in order by the time they leave the other end of the Mikrotik router. 
At a small penalty of latency, re-ordering could be acheived. Its also 
possible that the end user VPN protocols could also already take care of 
that. I don't know enoguh about the VPN venders to know which protocols 
self-correct/guarantee correct packet ordering.


When using the per packet load balancing of theMikrotik, is the Mikrotik 
also the radio, apposed to it be jsut the router connected Ethernet to 
external radios of another brand. Its possible that without Ethernet 
involved in between that they jsut get to the destination in order more 
frequently.


Running per packet load balancing is much more reliable over circuits with 
fixed factors such as wired and fiber connections.  In an RF enviroment its 
a much different situation. There are many factors in RF that can cause a 
packet to get delayed in delivery individually. For example an RF link that 
automatically adjusts modulation when errors occur. Because two RF links may 
transfer at different rates, the packets could arrive at different times.


I did not specify previously, but when mentioning the risk of per packet 
load balancing, I was referring to using it within an RF environment.  And I 
was referring to it being used for loadbalancing for a PtP link.  Load 
balancing per packet between two different ISP transit providers, also could 
result in serious out of order packet problems, thus justifying per session 
load balancing.


A PTP wired link, very well may be a preferred method to use per packet load 
balancing.

 Running a EoIP tunnel across both the T1 and your link you should be 
 able

 to
 load-balance across both links for incoming and outgoing traffic by
 bonding
 both EoIP interfaces at the customer site and your Mikrotik box. I have
 done
 this in the past but it has been across a couple of wireless links with
 similar round trip delays. If you use per-packet load balancing there 
 may

 be
 issues with packets arriving out of order but if you do it per session 
 it

 should work fine. With per session load balancing you won't get an
 aggregate
 throughput of both links with a single stream but should use both links 
 if

 multiple streams are flowing.

  Running a EoIP tunnel across both the T1 and your link you should be able
  to
  load-balance across both links for incoming and outgoing traffic by
  bonding
  both EoIP interfaces at the customer site and your Mikrotik box. I have
  done
  this in the past but it has been across a couple of wireless links with
  similar round trip delays. If you use per-packet load balancing there may
  be
  issues with packets arriving out of order but if you do it per session it
  should work fine. With per session load balancing you won't get an
  aggregate
  throughput of both links with a single stream but should use both links if
  multiple streams are flowing.
 
  Cheers,

  A little feedback from the collective is appreciated here. I have a high
  school who has bought a connection from me but is also stuck with an old
  T1 circuit under contract for the next 3 years. They want both
  connections to be used all the time and for all traffic to automatically
  go through the working connection if one fails. Basically they want load
  balancing and failover. All addresses are nat'd private space IPs.  I
  would think I should be able to do this with Mikrotik and/or Star OS but
  I do not know how. Your thoughts  and or other suggestions are highly
  appreciated. If only failover or only load balance is possible then
  suggestions on that are welcome also. By the way, the T1 provider is not
  me and will likely not work with me unfortunately. We have to leave
  their network settings intact.
