Systems and methods for controlling the transmission of relatively large data objects in a communications system

A method for controlling the transmission of relatively large data objects among a plurality of domains, each of said domains representing an application capable of processing relatively large data objects, in a communications system in which performance is optimized only for the efficient transmission of relatively small data objects between the plurality of domains, the communications system having a plurality of buffers for storing relatively large data objects therein, said method comprising the steps of:

• storing a relatively large data object in a first buffer of said plurality of buffers;
• processing the relatively large data object stored in the first buffer of said plurality of buffers using a first domain of said plurality of domains and a second domain representing a second application capable of processing the relatively large data object stored in the first buffer of said plurality of buffers;
• and
• assigning ownership of said first buffer having a relatively large data object stored therein to a first domain of said plurality of domains;
• transmitting the first buffer having a relatively large data object stored therein from said first domain to a second domain of said plurality of domains without requiring physical movement of the relatively large data object stored in the first buffer and without requiring creation of a copy of the relatively large data object stored in the first buffer;
• and
• processing the relatively large data object stored in the first buffer using a second domain of said plurality of domains.

A computer program product for controlling the transmission of relatively large data objects in a communications system in which performance is optimized only for the efficient transmission of relatively small data objects, the communications system having a plurality of domains, each of said domains representing an application capable of processing relatively large data objects when executed on a processing unit, and a plurality of buffers for storing relatively large data objects therein, said computer program product comprising:

• a computer readable storage medium having computer readable code means embodied in said medium, said computer readable code means comprising:
• computer instruction means for storing a relatively large data object in a first buffer of said plurality of buffers;
• computer instruction means for processing the relatively large data object stored in the first buffer of said plurality of buffers using a first domain of said plurality of domains and a second domain representing a second application capable of processing the relatively large data object stored in the first buffer of said plurality of buffers;
• computer instruction means for assigning ownership of said first buffer having a relatively large data object stored therein to a first domain of said plurality of domains;
• computer instruction means for transmitting the first buffer having a relatively large data object stored therein from said first domain to a second domain of said plurality of domains without requiring physical movement of the relatively large data object stored in the first buffer and without requiring creation of a copy of the relatively large data object stored in the first buffer;
• and
• computer instruction means for processing the relatively large data object stored in the first buffer using a second domain of said plurality of domains.
