1. DESCRIPTION
Ipvsadm is used to set up, maintain or inspect
the virtual server table in the Linux kernel.
The Linux Virtual Server can be used to
build scalable network services
based on a cluster of two or more nodes.
The active node of the cluster redirects service requests to
a collection of server hosts
that will actually perform the services.
Supported features include
two protocols (TCP and UDP),
three packet-forwarding methods (NAT, tunneling, and direct routing),
and eight load balancing algorithms (
round robin,
weighted round robin,
least-connection,
weighted least-connection,
locality-based least-connection,
locality-based least-connection with replication,
destination-hashing,
and source-hashing
).
