Buffer Size Calculation in webex
For various types of publisher nodes, we have given examples of buffer sizes calculated using the following table.
CM publisher nodes with a buffer size of 50 MB will be calculated by default. Publisher nodes with a buffer size of 20 MB will be calculated by default for IM&P publisher nodes with a buffer size of 50 MB.
There is a default buffer size of 20 MB set for all subscriber nodes in the network.
