Source VIPA
Source VIPA is particularly suitable for high-performance environments. It selects one source address out of a range of source addresses when it replaces the source address of a socket.
Some operating system kernels cannot do load balancing among several connections with the same source and destination address over several interfaces. The solution is to use several source addresses.
To achieve load balancing, a policy must be selected in the policy section of the configuration file of Source VIPA (/etc/src_vipa.conf). In this policy section, you can also specify several source addresses that are used for one destination. Source VIPA then applies the source address selection according to the rules of the policy that is selected in the configuration file.
This Source VIPA solution does not affect kernel stability. Source VIPA is controlled by a configuration file that contains flexible rules for when to use Source VIPA based on destination IP address ranges.
You can use IPv6 or IPv4 addresses for Source VIPA. IPv6 addresses are supported as of Source VIPA 2.1.0.
