Thus LVS will have to do on average n/2 traversals instead of n/2^(IP_VS_CONN_TAB_BITS+1) traversals. The real effect is to amplify traversal times by 2^IP_VS_CONN_TAB_BITS.

WebThe broadcast address of the virtual ip address is itself, and the subnet mask is 255.255.255.255. Why has to be this way? Because several machines need to use the same ip address, using itself as the broadcast address and setting the subnet mask to 4 255 will not cause ip address conflicts, otherwise lvs will not be able to forward access ...
