to calculate the required network bandwidth based on the redo generation rate on the primary database
The formula used (assuming a conservative TCP/IP network overhead of 30%) for calculating the network bandwidth is :
Required bandwidth = ((Redo rate bytes per sec. / 0.7) * 8) / 1,000,000 = bandwidth in Mbps
Let us assume the redo rate is a 500 KB/sec.
Required bandwidth = ((Redo rate bytes per sec. / 0.7) * 8) / 1,000,000 = bandwidth in Mbps
Required bandwidth = ((512000/0.7) * 8) /1,000,000
Required bandwidth = 4.85 Mbps
