Abstract

Claims (23)

1. A data distribution method comprising:

configuring, by a data formatter, a buffer in a memory to store data in a plurality of partitionable data levels, the plurality of partitionable data levels being organized in descending levels of interest;

sending, by a data sender, to at least one of a plurality of subscriber devices, from the buffer, a first message comprising a first requested data level and all data levels having a level of interest that is greater than or equal to the level of interest of the first requested data level; and

sending, by the data sender, to at least a further one of the plurality of subscriber devices, from the buffer, a second message comprising a second requested data level and all data levels having a level of interest that is greater than or equal to the level of interest of the second requested data level, wherein the second message is sent without remarshaling of the data in the buffer by the data formatter.

2. The data distribution method of claim 1 , further comprising: storing a header, the header including bookkeeping information associated with the plurality of partitionable data levels.

3. The data distribution method of claim 2 , wherein the bookkeeping information comprises a number of the partitionable data levels.

4. The data distribution method of claim 1 , wherein, to send the first message, the data sender places a socket write call referencing the buffer and a length to include the first requested data level and all of the levels having a level of interest that is greater than or equal to the level of interest of the first requested data level.

5. The data distribution method of claim 1 , further including generating a first partition table, the first partition table to indicate a first partitionable location of the plurality of partitionable data levels and a second partitionable location of the plurality of partitionable data levels.

6. A non-transitory computer readable medium comprising instructions which, when executed, cause a machine to at least:

configure a buffer in a memory to store data in a plurality of partitionable data levels, the plurality of partitionable data levels being organized in descending levels of interest;

send, to at least one of a plurality of subscriber devices, from the buffer, a first message comprising a first requested data level and all data levels having a level of interest that is greater than or equal to the level of interest of the first requested data level; and

send, to at least a further one of the plurality of subscriber devices, from the buffer, a second message comprising a second requested data level and all data levels having a level of interest that is greater than or equal to the level of interest of the second requested data level, wherein the second message is sent without remarshaling of the data in the buffer by the data formatter.

7. The non-transitory computer readable medium of any one of claim 6 , wherein the instructions further cause the machine to store a header, the header including bookkeeping information associated with the plurality of partitionable data levels.

8. The non-transitory computer readable medium of claim 7 , wherein the bookkeeping information comprises a number of the partitionable data levels.

9. The non-transitory computer readable medium of any one of claim 6 , wherein, to send the first message, the instructions cause the machine to place a socket write call referencing the buffer and a length to include the first requested data level and all of the levels having a level of interest that is greater than or equal to the level of interest of the first requested data level.

10. The non-transitory computer readable medium of any one of claim 6 , wherein the instructions further cause the machine to generate a first partition table, the first partition table to indicate a first partitionable location of the plurality of partitionable data levels and a second partitionable location of the plurality of partitionable data levels.

11. A data distribution system for distributing data to a plurality of subscriber devices, the data distribution system comprising:

a memory;

a data formatter to configure a buffer in the memory to store data in a plurality of partitionable data levels, the plurality of partitionable data levels being organized in descending levels of interest; and

a data sender to send to at least one of the subscriber devices, from the buffer, a first message comprising a first requested data level and all data levels having a level of interest that is greater than or equal to the level of interest of the first requested data level and to send to at least a further one of the plurality of subscriber devices, from the buffer, a second message comprising a second requested data level and all data levels having a level of interest that is greater than or equal to the level of interest of the second requested data level, wherein the second message is sent without remarshaling of the data in the buffer.

12. The data distribution system of claim 11 , wherein the data formatter further configures the buffer to store a header, the header including bookkeeping information associated with the plurality of partitionable data levels.

13. The data distribution system of claim 12 , wherein the bookkeeping information comprises a number of the partitionable data levels.

14. The data distribution system of claim 11 , wherein, to send the first message, the data sender places a socket write call referencing the buffer and a length to include the first requested data level and all of the levels having a level of interest that is greater than or equal to the level of interest of the first requested data level.
