The Local Node Feature

This page contains information about the Local Node feature of LinuxDirector.

If the local node feature is enabled, the load balancer can not only redirect the packets of the specified port to the other servers (remote nodes) to process it, but also can process the packets locally (local node). Which node is chosen depends on the scheduling algorithms. This local node feature can be used to build a virtual server of a few nodes, for example, 2, 3 or more sites, in which it is a resource waste if the load balancer is only used to redirect packets. It is wise to direct some packets to the local node to process.

This feature can also be used to build distributed identical servers, in which one is too busy to handle requests locally, then it can seamlessly forward requests to other serversto process them.This feature can be applied to both virtual server via NAT and virtual server via IP tunneling.

 

More information needs to be added, such as kernel building intructions, running examples, figures and so on.
