hi mikko :-)
|
|
[13:35] pieterh
|
random question, have you ever used epgm://?
|
|
[13:35] mikko
|
not really
|
|
[13:36] pieterh
|
i'm experimenting with this for some p2p group messaging
|
|
[13:36] pieterh
|
my idea is to hash group names to multicast addresses
|
|
[13:37] pieterh
|
I guess I'll use the "poke a stick at it and see if it moves" technique
|
|
[13:44] drbobbeaty
|
pieterh: I've actually used the hashing technique you talk about to broadcast messages over 270+ epgm:// channels. It works very nicely.

Is it safe to run 2.1.9 and 2.1.7 peers together or should I bring down everything, mass upgrade and bring back up on the same version?
|
|
[14:47] cremes
|
sshirokov: i believe all of the 2.1.x series are mutually compatible
|
|
[14:47] cremes
|
so you should be able to mix them
|
|
[14:48] sshirokov
|
That doc'd anywhere?
|
|
[14:48] cremes
|
no; why would you think that a patch release would be incompatible with an earlier patch release?
|
|
[14:48] sshirokov
|
Just being overly cautious
|
|
[14:49] cremes
|
ok
|
|
[15:10] pieterh
|
drbobbeaty: hi
|
|
[15:11] pieterh
|
sshirokov: yes, the interoperability is guaranteed by the version number

Thanks!
|
|
[15:12] pieterh
|
drbobbeaty: stupid question perhaps, but does epgm have simpler requirements wrt routers?
|
|
[15:13] drbobbeaty
|
pieterh: not really, but it's not bad. You just have to make sure the UDP multicast channels are available across the routers/switches. In our case, we found that we had some switches that only allowed 1000 UDP Multicast channels - this was a problem as we wanted to have many more than that. We have ended up getting new switches that can carry far more multicast channels as a result.
|
|
[15:14] pieterh
|
aight
|
|
[15:14] drbobbeaty
|
pieterh: In general, TCP is the most easily routed, but in a limited environment, the epgm is very nice.
|
|
[15:15] pieterh
|
drbobbeaty: how does it work with more than 255 devices?
|
|
[15:16] drbobbeaty
|
We've never pushed it that hard. Right now, I'm looking at about 20 receivers for a given sender - tops.

will there be a 2.1.10 or will 2.1.9 -> 2.2?
|

|
|
[16:11] dcolish
|
thanks
|
|
[16:11] pieterh
|
there will be a 2.1.10, yes
|
|
[16:11] pieterh
|
there will be maintenance releases of 2.1.x as long as there are users and patches
|
|
[16:28] dcolish
|
ok thats good to know, thanks pieterh
|
|
[16:29] dcolish
|
it doesnt look like issue-207 would help my problems, but i'm much more aware of how name resolution works for tcp:// in zmq
|
|
[16:39] pieterh
|
dcolish: what are your problems?
|
|
[16:47] dcolish
|
well, we forgot to roll out a dns host name and that causes the zmq resolver to fail
|
|
[16:48] dcolish
|
i dont think its zmq's responsibility to fix that
|
|
[16:48] dcolish
|
in fact, its really nice that it crashed early
|
|
[16:49] mikko
|
pieterh: sent you an email
|
|
[16:49] mikko

this is like live notification system

hi mikko, was out at lunch
|
