We are building a any to any MPLS network with 70 sites.
Our network will have a central DC with multiple spoke locations.
Using Multicast application server (Omnicast) We want to push 250GB image file from central location to all the spoke locations. File should be transferred within 7hours. For the same we want to know the bandwidth that will be required...as per practical calculation it is coming somewhere near 100Mbps.
Please suggest. Also is there any application level fine tuning required to push the 200GB file in 7Hours.
Attached architecture for reference.
