RubenKelevra Posted July 17, 2013 Report Share Posted July 17, 2013 I've been searching for something in my network with wireshark as I'd realized that BTSync sends 8-10 multicast-packets for LAN-peer-find per second while connected via WiFi to my network.Is that a bug or a nice feature to force the users to get gigabit-switches?

GreatMarko Posted July 17, 2013 Report Share Posted July 17, 2013 You can always turn off the "Search LAN" setting (a per folder setting) to reduce significantly the amount of multicast traffic on your local network! With this setting disabled, if your local devices can't then find each other, but they all have static IPs, you could use the "pre-defined hosts" options to identify them to Sync Quote Link to comment Share on other sites More sharing options...

Thats pretty much traffic without any reason, because if another computer added to the network the lan-peer-find would start from the other end.

RubenKelevra Posted July 17, 2013 Author Report Share Posted July 17, 2013 Okay, with the beta version the packets per second is reduced to the number of folders which got no devices connected.But this is still way to much. Once in 5 minutes would be enouth, because another pc would send also packets to find this pc.Running the now latest version on Windows 8.

fukawi2 Posted July 18, 2013 Report Share Posted July 18, 2013 I agree that this should be significantly reduced, to at most 1/minute.What I'm not sure about; are these "announcements" or "solicitations"? Quote Link to comment Share on other sites More sharing options...
srf21c Posted January 30, 2014 Report Share Posted January 30, 2014 I fired up tcpdump on my LAN today to troubleshoot another network problem ran into this issue. The frequency of multicast udp port 3838 packets generated by BitTorrent sync clients IS INSANE. Once a minute would be more reasonable, this eight broadcast packets per second nonsense fills my captures with junk and is highly annoying. I'd like the BitTorrent developers to share the thought process behind this decision with the end users. Help us understand. Quote Link to comment Share on other sites More sharing options...
hawibtsync Posted January 30, 2014 Report Share Posted January 30, 2014 Just a question: Is it 8 packets per second per share or is it independant from the number of shares? Thanks Quote Link to comment Share on other sites More sharing options...
GreatMarko Posted January 30, 2014 Report Share Posted January 30, 2014 Just a question: Is it 8 packets per second per share or is it independant from the number of shares?  I would suggest that the number of multicast packets being sent is directly related to the number of folders you've added to sync, given than the "Search LAN" setting (which is what produces these multicast packets), is a per folder setting. i.e. if you're syncing 8 folders, you'll see x8 more multicast packets than if you'd just added a single folder to sync. I agree this could certainly be better optimized than at present, but until then, if the amount of multicast traffic is causing you network issues, see my workaround earlier in this thread.

lolcat Posted January 30, 2014 Report Share Posted January 30, 2014 By folders do you mean shares? It is confusing when we don't use the same terminology.Share: A sync folderFolder: An actual folder, a share can contain many folders Quote Link to comment Share on other sites More sharing options...
GreatMarko Posted January 30, 2014 Report Share Posted January 30, 2014 By folders do you mean shares? It is confusing when we don't use the same terminology. I mean "folder" as in a folder you add to sync, which is then listed in the "Folders" tab of the UI. I would refer to the folders within each folder you add to Sync as "sub folders"  Share: A sync folder...or "share" meaning a device/node running Sync!  I think my reply was pretty clear, but to clarify:If 8 folders are shown in your Sync UI (i.e. you've added 8 folders directly to your Sync, each with their own Secret), and you have "Search LAN" enabled for each of these 8 folders, I suspect you'll see x8 more multicast packets on your network (regardless of the number of sub-folders) than if there is only 1 folder shown in your Sync UI.

lolcat Posted January 30, 2014 Report Share Posted January 30, 2014 That seems unfortunate. I hope they reduce the multicast traffic and the issue with small files. Quote Link to comment Share on other sites More sharing options...
