Re: GnuGK and Peer Element support

Hi,

Thanks again Jan. I
want to know whether GnuGK as a border element provides replicating its
own routing database to the other gatekeepers in it's administrative
domain or not. Roughly speaking, in the case of border element failure,
we want each gatekeeper in the zone to have routing table similar to
that of border element before it's failure. Therefore, each gatekeeper
would have the complete routing table itself, enabled to continue
operation while the border element is down.

Best,
Hossein

  Hi Hossein,

you can configure whether to forward or not. Take a look at the
Neighbor section in the manual:
http://www.gnugk.org/gnugk-manual-10.html

Caching all results of LRQs takes a more advanced config, but I've
already done that with GnuGk for clients whose lookups were very
expensive. You have to intercept the lookup results and store them in a
database and then use the 'sql' policy to retrieve them again (at least
thats one way to do it).

Regards,
Jan

    Dear Simon,

Thank you for your answer. To make myself sure, will the GnuGK as a 
border element have a caching mechanism inside, building a routing 
table? In other words, having a GnuGK as a border element, does the LRQ 
messages are resolved by the border element without going outside the 
domain?

GnuGk certainly can operate as a border element. You only need to have an 2
network interfaces one on the inside and one on the outside. There are no
special configuration required, the gatekeeper will detect the 2 interfaces
and should automatically accept registrations and route signalling and media
between the two networks.

Subject:  GnuGK and Peer Element support

Hi

Does anyone help me know whether the GnuGK supports the peer element (border
element) concept or not. In other words, would it be possible to have a
border element in a platform consisting the H323plus library and GnuGK? And
if so, is there any documentation or hints about this matter?

Any help would be appreciated.

Best,

Hossein Aminaiee
