• modules built: ip_vs_mh

Help text

The maglev consistent hashing scheduling algorithm provides the Google's Maglev hashing algorithm as a IPVS scheduler. It assigns network connections to the servers through looking up a statically assigned special hash table called the lookup table. Maglev hashing is to assign a preference list of all the lookup table positions to each destination.

Through this operation, The maglev hashing gives an almost equal share of the lookup table to each of the destinations and provides minimal disruption by using the lookup table. When the set of destinations changes, a connection will likely be sent to the same destination as it was before.

If you want to compile it in kernel, say Y. To compile it as a module, choose M here. If unsure, say N.
