Interface Summary

Interface	Description
AbstractHostLBSPolicy.InitParams
AbstractLBSPolicy.InitParams
IHALoadBalancerPolicy	Load balancer policy interface.
IHAPolicyLifeCycle
IHARequestURIRewriter	Interface for rewriting the Request-URI once the load balancer has determined the target host and service to which the request will be proxied.
IHostMetrics	Generic interface exposes an abstract model of the performance metrics for a given host.
IHostScoringRule	Interface for scoring the load on a host.

Class Summary

Class	Description
AbstractHostLBSPolicy	Abstract base class for an LBS policy that uses per-host load metrics.
AbstractHostMetrics
AbstractLBSPolicy	Abstract base class establishes a listener for quorum events, tracks the services that are members of the quorum, and caches metadata about those services (especially the requestURL at which they will respond).
DefaultHARequestURIRewriter	Default implementation.
HostScore	Helper class pairs a hostname and the normalized availabilty for that host.
HostTable	Class bundles together the set of HostScores for services that are joined with the met quorum and the HostScore for this service (iff it is joined with the met quorum).
NOPHostScoringRule	Returns ONE for each host (all hosts appear to have an equal workload).
ServiceScore	Helper class caches metadata about an HAGlue service.
TestAbstractHostLBSPolicy	Test suite for the basic stochastic load balancing mechanism for LBS policies based on actual host workloads regardless of how those workload metrics are obtained.
TestAll	Test suite.
