Bandwidth requirement calculation
In order to estimate the bandwidth needed the following calculation was used:

T = (d / t) * (8 bits/Byte + 2 bits/Byte overhead) * (1 hour / 3600)

T = Sustained WAN Bandwidth required to transfer data in Mbps
d = Amount of data to be transferred in Mbytes
t = Maximum amount of time allotted for transfer in hours

TCP Throughput calculation
In order to estimate the throughput, of a single TCP flow or session, the following calculation was used:

T = (w / l)

T = Maximum TCP session throughput in Bps
w = TCP stack window size in bytes
l = Roundtrip network latency in seconds
