Hi steve Please check the archives and the online documentation. (ie the command line page.)
Since you are using Windows, try --max-bitrate bitrate 10m|20m|40m. Etc...

Hi,
Thankyou for your answer, but I am using UDPCast in windows commandline, there are no examples included with the windows command-line programs. Could you be a little bit more specific please? Can you give me an example how to set these commandline parameters?
Much thanks in advance,
Steve Dubois

We are facing a problem when using UDPCast in multicast mode. When I start a transfer from one pc to another, no problem. I contacted network-support and they presume it could be a conflict with the VVPR (Virtual Router Redundancy Protocol) which also uses multicast. udp-sender --ttl 1 and udp-receiver --ttl 1 udp-sender --ttl 2 and udp-receiver --ttl 2 udp-sender --mcast-rdv-address 224.0.0.3 and udp-receiver --mcast-rdv-address 224.0.0.3 But the problem persists.
If possible, can you please verify what happens when udp-sender transmits at 10%, 20%, 40%, 80%, and/or 100% of the smallest pipe? --max-bitrate bitrate --rate-governor module.so:key1=value1,key2=value2 --bw-period seconds THIS MESSAGE IS FOR THE USE OF THE INTENDED RECIPIENT(S) ONLY AND MAY CONTAIN INFORMATION THAT IS PRIVILEGED, PROPRIETARY, CONFIDENTIAL, AND/OR EXEMPT FROM DISCLOSURE UNDER ANY RELEVANT PRIVACY LEGISLATION.

Hi Steve, It's possible that traffic is spilling onto a low baud rate pipe or traveling through a traffic shaper.
Please consider * verifying your packet / block size * verifying your insitu IP plan (if stuck, try different multicast ranges) * starting slower e.g. 512k|1m|2m|4m|... * verifying your ARP cache * if all else fails, verify executable hashes Original Message From: Brent Kimberley Sent: Tuesday, August 30, 2016 09:08 To: Dubois Steve Cc: 'udpcast@udpcast.linux.lu' Subject: Re: Problem: UDPCast transfer breaks DHCP leases
