5.3.9. Class RoundRobinChainer

This class is based on the StateBasedChainer class and encapsulates a real TCP/IP connection establishment, and is used when a top-level proxy wants to perform chaining. In addition to ConnectChainer this class adds the capability to perform stateful, load balance server connections among a set of IP addresses.

Example 5.15. A DirectedRouter using RoundRobinChainer
The following service definition uses a RoundRobinChainer class with two possible destination addresses. These destinations are used in a roundrobin fashion, alternating between the two destinations. Service(name="intra_HTTP_inter", router=DirectedRouter(dest_addr=(SockAddrInet('192.168.55.55', 8080), SockAddrInet('192.168.55.56', 8080)), forge_addr=FALSE, forge_port=Z_PORT_ANY, overrideable=FALSE), chainer=RoundRobinChainer(protocol=ZD_PROTO_AUTO, timeout_state=60000, timeout_connect=30000), max_instances=0, proxy_class=HttpProxy)
