Figure 36. After Polarization Eect
Trac ow after enabling ow-based hashing
When the ow-based hashing is enabled at all the nodes in the multi-tier network, trac distribution is balanced at all tiers of the network
nullifying the polarization eect. Trac occurs by the randomness for the ow-based hashing algorithm across multiple nodes in a given
network.
