`ABSTRACT
`(57)
`A method and system for demultiplexing packets of a mes
`sage is provided. The demultiplexing system receives packets
`of a message, identifies a sequence of message handlers for
`processing the message, identifies state information associ
`ated with the message for each message handler, and invokes
`the message handlers passing the message and the associated
`state information. The system identifies the message handlers
`based on the initial data type of the message and a target data
`type. The identified message handlers effect the conversion of
`the data to the target data type through various intermediate
`data types.
