Method and system for data demultiplexing
View Patent ↗A method and system for demultiplexing packets of a message is provided. The demultiplexing system receives packets of a message, identifies a sequence of message handlers for processing the message, identifies state information associated 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.
1. A method in a computer system for processing packets of a message, the method comprising:
receiving a first packet of the message;
selecting one or more addresses based on the first packet of the message;
identifying a sequence of one or more components based on the one or more addresses;
creating a path based on the sequence of one or more components;
storing the path in computer memory so that the sequence does not need to be re-identified for subsequent packets of the message; and
processing the packets of the message using the path.
2. The method of claim 1 , wherein the path is non-predefined before receiving the first packet of the message.
3. The method of claim 1 , wherein the path is a data structure containing a sequence of components for processing the packets of the message.
4. The method of claim 1 , wherein subsequent packets of the message use the same path as identified by the first packet of the message.
5. The method of claim 1 , wherein the identifying is based on one or more link layer addresses such as ethernet MAC addresses.
6. The method of claim 1 , wherein the identifying is based on one or more Internet layer addresses such as Internet Protocol addresses.
7. The method of claim 1 , wherein the identifying is based on one or more transport layer addresses such as TCP port addresses.
8. The method of claim 1 , wherein the identifying is based on one or more content identifiers such as a MIME type.
9. The method of claim 1 , wherein the identifying is based on one or more application identifiers.
10. The method of claim 1 , wherein the identifying is based on one or more user identifiers.
11. A non-transitory computer-readable medium containing instructions for processing packets of a message, the instructions comprising:
at least one computer-executable module configured to:
receive a first packet of the message;
select one or more addresses based on the first packet of the message;
identify a sequence of one or more components based on the one or more addresses;
create a path based on the sequence of one or more components;
store the path in computer memory so that the sequence does not need to be re-identified for subsequent packets of the message; and
process the packets of the message using the path.
12. The computer-readable medium of claim 11 , wherein the path is non-predefined before receiving the packets of the message.
13. The computer-readable medium of claim 11 , wherein the path is a data structure containing a sequence of components for processing the packets of the message.
14. The computer-readable medium of claim 11 , wherein subsequent packets of the message use the same path as identified by the first packet of the message.
15. The computer-readable medium of claim 11 wherein the identifying is based on mapping definitions and mapping definitions are specified through configuration information.
