Class BaseNode<T extends BaseNode<T>>

java.lang.Object

org.jclouds.cloudloadbalancers.domain.internal.BaseNode<T>

All Implemented Interfaces:

Comparable<BaseNode<T>>

Direct Known Subclasses:

Node, NodeRequest

public class BaseNode<T extends BaseNode<T>>
extends Object
implements Comparable<BaseNode<T>>

The nodes defined by the load balancer are responsible for servicing the requests received through the load balancer's virtual IP. By default, the load balancer employs a basic health check that ensures the node is listening on its defined port. The node is checked at the time of addition and at regular intervals as defined by the load balancer health check configuration. If a back-end node is not listening on its port or does not meet the conditions of the defined active health check for the load balancer, then the load balancer will not forward connections and its status will be listed as OFFLINE. Only nodes that are in an ONLINE status will receive and be able to service traffic from the load balancer.

All nodes have an associated status that indicates whether the node is ONLINE, OFFLINE, or DRAINING. Only nodes that are in ONLINE status will receive and be able to service traffic from the load balancer. The OFFLINE status represents a node that cannot accept or service traffic. A node in DRAINING status represents a node that stops the traffic manager from sending any additional new connections to the node, but honors established sessions. If the traffic manager receives a request and session persistence requires that the node is used, the traffic manager will use it. The status is determined by the passive or active health monitors.

If the WEIGHTED_ROUND_ROBIN load balancer algorithm mode is selected, then the caller should assign the relevant weights to the node as part of the weight attribute of the node element. When the algorithm of the load balancer is changed to WEIGHTED_ROUND_ROBIN and the nodes do not already have an assigned weight, the service will automatically set the weight to "1" for all nodes.
