Hello,
I am modifying my LCR setup and just wanted to get some confirmation that I
am following best practices. I am a
I am loading up 18,500 routes into the table which all belong to a single
group. There will be a single route in a second group which all non-matches
will fail over to.
That being said, this is what my configuration looks like:
modparam("lcr","lcr_hash_size", 20000)
modparam("lcr","fetch_rows", 5000)
This server has 8G of RAM and I am currently using 4M of private memory
(#define PKG_MEM_POOL_SIZE 4*1024*1024 ).
Thanks,
Geoff

A couple of other questions regarding LCR. Hopefully they are all
simple. I read the overview and exported method docs and didn't find
100% definitive answers to any of this:
1 - If I have 2 gateways with the same group id and the same weight,
will the LCR module route in a round-robin fashion between them, or
will each request try one of them first and then use the other as a
failover. (i believe it's round-robin, but i could be wrong)
2 - If I have 2 gateways that have a longer length match, and one that
has a default match i.e
prefix group_id
1555555 1
1 2
gateway_name group_id
carrier1-A 1
carrier1-B 1
carrier2 2
Would the following scenario hold true if I tried to dial 15555551212?
--> next_gw() from REQUEST_ROUTE
--> route to carrier1-A
--> carrier1-A returns a 503
--> next_gw() from FAILURE_ROUTE
--> route to carrier1-B
--> carrier1-B returns a 503
--> next_gw() from FAILURE_ROUTE
--> route to carrier2
--> 200 OK
Thanks!

they are chosen randomly, not round robin.

yes, that is what would happen or if carrier1-A and carrier1-B have same
weight, then either one of them would be the first to try.

Juha,
Thanks for the information. Much appreciated! Seeing as you are the
author of this module, what do you think the level of effort would be
to implement global round-robin functionality for gateways with the
same weight in the same group? Is there maybe a different module I
should be looking into for the more advanced routing functionality?
Perhaps carrierroute would be more flexible?
thanks!

then the module would need to remember, which gw was used during
processing of previous request, i.e., per group state would need to be
kept from one request to the next. there would be ways to do so, e.g.,
using htable module, but effort would not be trivial.
should be looking into for the more advanced routing
functionality?

i have no experience with carrierroute, but perhaps it could support
what you want.

Hi Geoffrey,
yes, you can have more control with cr. Its possible to specify nearly
arbitrary failover logic with help of the failure_route table. But this comes
with a price, its not that convinient then to use the lcr module, though.
Take a look at the example 1.22 in the cr documentation to get an idea.
Cheers,
Henning
