6.4.5.7. RoundRobinChainer

RoundRobinChainer is similar to FailoverChainer, but Application-level Gateway directs each incoming connection to the next available server. That way the load is balanced between the servers set in the destination list of the router. Use the RoundRobinChainer together with the DirectedRouter.

Tip

RoundRobinChainer can be used to implement simple load balancing for the protected servers.

Configuring RoundRobinChainer

Figure 6.38. Configuring RoundRobinChainer

RoundRobinChainer has the following options:

Keep availability state for

Application-level Gateway does not try to connect to an unreachable server until the time set in the Keep availability state for option expires.

Connection timeout

Assume that the server is unreachable if it cannot be connected for Connection timeout seconds.

Protocol action

It defines the type of the protocol used in the server-side connection. The default is to use the same protocol as on the client side, but PNS can enforce the use of TCP or UDP protocol.
