Routing instant messages using configurable, pluggable delivery managers

摘要

Configurable, pluggable delivery managers are responsible for routing instant messages to intended recipients. A delivery manager is selected for a particular message, and that delivery manager defines, at runtime, a delivery policy to be used to route the instant message to an intended recipient of the message. The delivery policy is based upon a configuration of the delivery manager, a user configuration of the intended recipient, and one or more available delivery mechanisms. The delivery manager routes the instant message using the delivery policy.
