MultiCast question
-
Hello Everyone,
I have multicast up and running and everything is working on our network. In testing when monitoring the network we noticed that the FoG server uses the same MultiCast group ID for each active multicast session, and we measured increased throughput on each of the links to the different multicasts but had slower speeds reported by PartClone on the clients and slower times for the transfer once the multicast was done.We are replacing Symantec Ghost and in the Ghost Server application by default there was an option to select a range of MultiCast addresses, is there that functionality in FoG, if not how does the FoG server handle multiple MultiCasts?

@Miodog I have to admit that I have not played with those advanced multicast settings in a while but we do have some in the web UI -> FOG Configuration -> FOG Settings -> section Multicast settings: UDPCAST STARTINGPORT and MULTICAST ADDRESS.
If those settings don’t suite your situation I am sure we can add udpcast options as needed. Just let us know.

Hi Sebastian, in that GUI interface can you give it a range of IP addresses to use?
So when multiple multicasts are started the Group ID is different for each one?
-
@Miodog If I remember right in the code that multicast address should be the base address each new multicast should increment that base address by one. This was done because it was discovered that by changing the mutlicast address it was faster when multiple streams were running at one time over increment just the multicast port number.
So in short this address can not be a range, but a starting point.

@Miodog Please let us know if we can improve the Multicast address thing within FOG even more. We are open for any kind of suggestion on this.
