6.4.5.6. FailoverChainer

FailoverChainer is similar to ConnectChainer, and attempts to connect to the destination defined by the router. However, if the destination is unreachable and the service uses DirectedRouter, Zorp attempts to connect to the next destination set in the router.

Tip

FailoverChainer can be used to implement a simple high availability support for the protected servers.

Configuring FailOverChainer

Figure 6.37. Configuring FailOverChainer

FailoverChainer has the following options:

Keep availability state for

Zorp 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 Zorp can enforce the use of TCP or UDP protocol.
