Abstract

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.

Claims

1. A method, comprising:

receiving, at a computing device having a processing circuit, a packet of a message;

determining, by the computing device, a key value for the packet, wherein the key value is determined based on one or more headers in the packet; and

using, by the computing device, the key value to determine whether the computing device is currently storing a previously created path for the key value

in response to determining that no path is currently stored for the key value, the computing device;

identifying, using the key value, one or more routines for processing the packet, including a routine that is used to execute a Transmission Control Protocol (TCP) to convert packets having a TCP format into a different format;

creating a path using the identified one or more routines wherein the created path stores state information for at least one of the identified one or more routines and specifies an ordering in which the identified one or more routines are to be performed to process the packet; and

processing the packet using the created path.
