Routing instant messages using configurable, pluggable delivery managers

Abstract

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.

1 . A system of routing instant messages, said system comprising:
 a computer system to include instructions to execute a method, said method comprising:
 selecting a delivery manager from a plurality of available delivery managers, via a client application to route an instant message to an intended recipient of the instant message, wherein said delivery manager is pluggable; 
 configuring said delivery manager at runtime via the client application, wherein said configuring comprises selecting a configuration for said delivery manager from a plurality of configurations using content of the instant message; 
 querying, by the delivery manager, a user configuration database of the intended recipient to determine one or more available delivery mechanisms supported by the intended recipient; 
 querying, by the delivery manager, a delivery mechanism database to determine the active delivery mechanisms of the client application available for routing the instant message; 
 identifying, by the delivery manager, one or more delivery mechanisms that are common to a result of the querying of the user configuration database and the querying of the delivery mechanism database to yield one or more possible delivery mechanisms; 
 selecting, by the delivery manager, from the one or more possible delivery mechanisms, at least one delivery mechanism supported by the delivery manager; and 
 routing, by the delivery manager, the instant message to the intended recipient using the at least one delivery mechanism. 
   
   
   
       2 . The system of  claim 1 , wherein said at least one delivery mechanism supported by the delivery manager is included within the configuration of the delivery manager. 
   
   
       3 . The system of  claim 1 , wherein said routing comprises dispatching, by the delivery manager, the instant message to one or more delivery mechanisms of the at least one delivery mechanism in accordance with a policy specified by said configuration of the delivery manager. 
   
   
       4 . The system of  claim 1 , wherein at least one available delivery mechanism of said one or more available delivery mechanisms is pluggable. 
   
   
       5 . The system of  claim 1 , wherein the delivery manager comprises a routing logic module. 
   
   
       6 . The system of  claim 1 , further comprising creating an instance of the delivery manager based on the selected particular delivery managers. 
   
   
       7 . The system of  claim 1 , wherein the selecting the configuration based on content comprises selecting the configuration based on priority of the instant message to be routed. 
   
   
       8 . At least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform a method of routing instant messages, said method comprising:
 selecting a delivery manager from a plurality of available delivery managers, via a client application to route an instant message to an intended recipient of the instant message, wherein said delivery manager is pluggable;   configuring said delivery manager at runtime via the client application, wherein the configuring comprises selecting a configuration for said delivery manager from a plurality of configurations using content of the instant message;   querying, by the delivery manager, a user configuration database of the intended recipient to determine one or more available delivery mechanisms supported by the intended recipient;   querying, by the delivery manager, a delivery mechanism database to determine the active delivery mechanisms of the client application available for routing the instant message;   identifying, by the delivery manager, one or more delivery mechanisms that are common to a result of the querying of the user configuration database and the querying of the delivery mechanism database to yield one or more possible delivery mechanisms;   selecting, by the delivery manager, from the one or more possible delivery mechanisms, at least one delivery mechanism supported by the delivery manager; and   routing, by the delivery manager, the instant message to the intended recipient using the at least one delivery mechanism.   
   
   
       9 . The at least one program storage device of  claim 8 , wherein said at least one delivery mechanism supported by the delivery manager is included within the configuration of the delivery manager. 
   
   
       10 . The at least one program storage device of  claim 8 , wherein said routing comprises dispatching, by the delivery manager, the instant message to one or more delivery mechanisms of the at least one delivery mechanism in accordance with a policy specified by said configuration of the delivery manager. 
   
   
       11 . The at least one program storage device of  claim 8 , wherein at least one available delivery mechanism of said one or more available delivery mechanisms is pluggable. 
   
   
       12 . The at least one program storage device of  claim 8 , wherein the delivery manager comprises a routing logic module. 
   
   
       13 . The at least one program storage device of  claim 8 , further comprising creating an instance of the delivery manager based on the selected particular delivery managers. 
   
   
       14 . The at least one program storage device of  claim 8 , wherein the selecting the configuration based on content comprises selecting the configuration based on priority of the instant message to be routed.
