Method for data delivery in a network

A method for receiving data from a sender queue of a sender intermediate layer of a protocol stack by a receiver queue of a receiver intermediate layer of the protocol stack implemented with a sliding window protocol, the method comprising:

• reading a data window from a receiver transport layer of the protocol stack, the data window comprising a data message or a collection of data messages tagged with a unique identifier, the data window received from the sender queue of the sender intermediate layer;
• writing the data window to the receiver queue, the receiver queue configured to store a plurality of data windows received from the receiver queue;
• receiving a commit message from a receiver messaging layer of the protocol stack after the receiver messaging layer reads all of the data window from the receiver queue;
• removing the data window from the receiver queue;
• sending an acknowledgement message to the sender intermediate layer, wherein the acknowledgement message includes information of available data storage capacity of the receiver queue;
• and
• calculating a round-trip time, wherein the round trip time is the amount of time the receiver messaging layer takes to read the data window from the receiver queue and to send the commit message to the receiver intermediate layer.

A computer program for transmitting data between a sender queue of a sender intermediate layer of a protocol stack and a receiver queue of a receiver intermediate layer of the protocol stack implemented with a sliding window protocol, the protocol stack including a sender application, a sender messaging layer, the sender intermediate layer, a sender transport layer, a receiver application, a receiver messaging layer, the receiver intermediate layer, and a receiver transport layer, wherein the sender transport layer and the receiver transport layer are coupled by way of a network layer, the computer program comprising instructions stored in a non-transitory computer readable storage medium, the instructions executable by a processor for:

• receiving a collection of data messages from the sender messaging layer to be communicated to the receiver application;
• tagging the collection of data messages with a unique identifier;
• writing the collection of data messages tagged with the unique identifier as a data window in the sender queue of the sender intermediate layer, the sender queue configured to store a plurality of data windows, wherein each data window of the plurality of data windows includes a data message or a plurality of data messages;
• transmitting a front data window of the sender queue of the sender intermediate layer to the receiver queue of the receiver intermediate layer;
• receiving a single receipt-acknowledgement message after the receiver transport layer of the protocol stack has received all of the front data window;
• and
• receiving a commit-acknowledgement message after the receiver messaging layer of the protocol stack has read from the receiver intermediate layer all of the front data window, wherein the commit-acknowledgement message includes information of available data storage capacity of the receiver queue.
