The locality-based least-connection with replication scheduling
algorithm is also for destination IP load balancing. It is
usually used in cache cluster. It differs from the LBLC scheduling
as follows: the load balancer maintains mappings from a target
to a set of server nodes that can serve the target. Requests for
a target are assigned to the least-connection node in the target's
server set. If all the node in the server set are over loaded,
it picks up a least-connection node in the cluster and adds it
in the sever set for the target. If the server set has not been
modified for the specified time, the most loaded node is removed
from the server set, in order to avoid high degree of replication.
If you want to compile it in kernel, say Y. To compile it as a
module, choose M here. If unsure, say N.
