+ ---help---
+ 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.

+ The maglev hashing scheduler maps source IPs to destinations
