Isochronous channel having a linked list of buffers

A computer system, comprising:

• an isochronous channel having a linked list of buffers configured to receive isochronous data transmitted within said computer system, each buffer comprising a data field for storing the isochronous data and a condition field for storing condition data to be evaluated;
• a sender client associated with said isochronous channel and configured to transmit said isochronous data, said sender client being a software driver routine associated with a sender node of said computer system;
• and
• a listener client associated with said isochronous channel and configured to receive said isochronous data, said listener client being a software driver routine associated with a listener node of said computer system, and said listener client loading the isochronous data into the linked list of buffers and evaluating the condition data in the condition field of each buffer to determine a next buffer from which to next access isochronous data;
• and
• wherein said sender client has an associated channel identifier that is provided to said listener client.

A computer readable medium for handling of real time data transmitted on an isochronous channel within a computer system, the computer readable medium comprising:

• a program, executable on the computer system, for configuring a linked list of buffers, each buffer comprising a data field for storing the isochronous data, a condition field for storing condition data to be evaluated;
• a first pointer field for storing a first pointer to one of the buffers from which isochronous data is to be next accessed in response to the condition data satisfying the condition;
• and a second pointer field for storing a second pointer to one of the buffers from which isochronous data is to be next accessed in response to the condition data not satisfying the condition;
• and
• a program, executable on the computer system for receiving the isochronous data from a source device, loading the isochronous data into the linked list of buffers, evaluating the condition data in the condition field;
• and responsively using either the first pointer or the second pointer to next access isochronous data from one of the buffers.

A computer implemented method for handling of real time data transmitted on an isochronous channel within a computer system, the method comprising:

• establishing a linked list of buffers for receiving isochronous data from a source device, each buffer comprising a data field for storing the isochronous data, a condition field, a first pointer field for storing a first pointer to one of the buffers from which isochronous data is to be next accessed in response to the condition data, and a second pointer field for storing a second pointer to one of the buffers from which isochronous data is to be next accessed in response to the condition data;
• receiving the isochronous data from the source device;
• loading the isochronous data into the linked list of buffers;
• accessing the data in the linked list of buffers for output to a client device;
• and
• responsive to an evaluation of the condition data, using the first pointer or second pointer to access a next buffer.
