Abstract

The present disclosure involves systems, software, and computer implemented methods for providing high speed communication between a sending system and a receiving system. One computer-implemented method includes determining, by a computer, that data is available for serialization using a pointer transfer; getting a data block of the data from a memory; getting metadata corresponding to the data block; writing an original address of the data block to a transport layer; writing the data block to the transport layer; determining that the data corresponding to the data block contains pointers; and adding a referenced data block to one or more data blocks to be transferred to a receiving system.

Claims

1. A computer-implemented method comprising:

determining, by a computer of a sending system, that data is available for serialization using a pointer transfer process;

retrieving a data block of the data from a memory of the sending system, wherein the memory of the sending system is different from a memory of a receiving system;

retrieving metadata corresponding to the data block;

writing an original address of the data block to a transport layer;

writing the data block to the transport layer;

determining that the data corresponding to the data block contains one or more pointers;

using the one or more pointers to reference another data block from the memory of the sending system; and

writing the another data block as a data block to the transport layer with one or more data blocks, including the data block, for transfer to the receiving system.

2. The method of claim 1, wherein writing a particular data block to the transport layer comprises adapting the data corresponding to the data block to requirements of the receiving system.

3. The method of claim 1, comprising determining whether data is available upon a determination that the data corresponding to the data block does not contain pointers.

4. The method of claim 1, comprising receiving the one or more data blocks for transfer to the receiving system.

5. The method of claim 4, comprising:

determining, by a computer of the receiving system, that data is available in the one or more data blocks;

retrieving a data block corresponding to the data from the transport layer;

retrieving the metadata corresponding to the data block; and

writing the data corresponding to the data block to the memory of the receiving system.

6. The method of claim 4, comprising:

determining, by a computer of the receiving system, that an unadapted pointer is available;

retrieving an original pointer value;

finding a data block in the memory of the receiving system where an original address equals the original pointer value; and

changing the unadapted pointer value to the address of the found data block in the memory of the receiving system.

7. The method of claim 1, wherein the metadata contains information about a memory layout of the data and data type information, including code page, floating point formats, and decimal places.

8. The method of claim 1 wherein one or more of the pointers are indirect pointers, the one or more indirect pointers each linked by zero or more other indirect pointers to a direct pointer that refers to a data block.

9. The method of claim 1 wherein the metadata is transferred to the receiving system.

10. A non-transitory, computer-readable medium storing computer-readable instructions executable by a computer and configured to:

determine on a sending system that data is available for serialization using a pointer transfer process;

retrieve a data block of the data from a memory of the sending system, wherein the memory of the sending system is different from a memory of a receiving system;

retrieve metadata corresponding to the data block;

write an original address of the data block to a transport layer;

write the data block to the transport layer;

determine that the data corresponding to the data block contains one or more pointers;

use the one or more pointers to reference another data block from the memory of the sending system; and

write the another data block as a data block to the transport layer with one or more data blocks, including the data block, for transfer to the receiving system.

11. The medium of claim 10, wherein writing a particular data block to the transport layer comprises adapting the data corresponding to the data block to requirements of the receiving system.

12. The medium of claim 10, wherein the instructions are configured to determine whether data is available upon a determination that the data corresponding to the data block does not contain pointers.

13. The medium of claim 10, wherein the instructions are configured to receive the one or more data blocks for transfer to the receiving system.

14. The medium of claim 10, wherein the instructions are configured to:

determine on the receiving system that data is available in the one or more data blocks;

retrieve a data block corresponding to the data from the transport layer;

retrieve the metadata corresponding to the data block; and

write the data corresponding to the data block to the memory of the receiving system.

15. The medium of claim 14, wherein the instructions are configured to:

determine that an unadapted pointer is available;

retrieve an original pointer value;

find a data block in the memory of the receiving system where an original address equals the original pointer value; and

change the unadapted pointer value to the address of the found data block in the memory of the receiving system.

16. A system, comprising:

a memory of a sending system different from a memory of a receiving system;

at least one hardware processor interoperably coupled with the memory of the sending system and the memory of a receiving system and configured to;

determine on the sending system that data is available for serialization using a pointer transfer process;

retrieve a data block of the data from a memory of the sending system;

retrieve metadata corresponding to the data block;

write an original address of the data block to a transport layer;

write the data block to the transport layer;

determine that the data corresponding to the data block contains one or more pointers;

use the one or more pointers to reference another data block from the memory of the sending system; and

write the another data block as a data block to the transport layer with one or more data blocks, including the data block, for transfer to the receiving system.

17. The system of claim 16, wherein writing a particular data block to the transport layer comprises adapting the data corresponding to the data block to requirements of the receiving system.

18. The system of claim 16, wherein the processor is configured to determine whether data is available upon a determination that the data corresponding to the data block does not contain pointers.

19. The system of claim 16, wherein the processor is configured to receive the one or more data blocks for transfer to the receiving system.

20. The system of claim 16, wherein the processor is configured to:

determine on the receiving system that data is available in the one or more data blocks;

retrieve a data block corresponding to the data from the transport layer;

retrieve the metadata corresponding to the data block; and

write the data corresponding to the data block to the memory of the receiving system.
