Abstract

A method, an apparatus, and a computer program product for transport protocol communications processing are provided. The apparatus may be an electronic device. The electronic device receives a transport protocol communications from a sender device. The electronic device generates a plurality of acknowledgments in response to the received transport protocol traffic and stores the plurality of acknowledgments at a first memory. A modem load for a modem of the electronic device is determined. The electronic device identifies the plurality of acknowledgments to identify a subset of the plurality of acknowledgments in response to the determined modem load satisfying a modem load threshold condition. The electronic device moves the subset of acknowledgments from the first memory to a second memory. The electronic device transmits the subset of acknowledgments to the sender device.

First claim

What is claimed is:

1. A method of Transport Protocol (TP) communications processing of an electronic device, comprising:
receiving TP traffic;
storing a plurality of ACKs at a first memory in response to the received TP traffic;
determining a modem load for a modem of the electronic device;
identifying a subset of ACKs of the plurality of ACKs in response to the determined modem load satisfying a modem load threshold condition, wherein a number of unique ACKs to be included in the subset of ACKs is based on a reduction factor N, wherein the reduction factor N is adjusted based on a memory utilization of the electronic device; and
moving the subset of ACKs from the first memory to a second memory.

2. The method of claim 1 , wherein the identifying comprises selecting all duplicate ACKs within the plurality of ACKs to be included in the subset of ACKs.

3. The method of claim 1 , wherein the reduction factor N is further adjusted based on at least one of a number of ACKs present in a time interval per flow or across all flows, the modem load, thermal status, or capacity of link carrying the plurality of ACKs.

4. The method of claim 3 , wherein the subset of ACKs comprises one ACK for every N unique ACKs of the plurality of ACKs.

5. The method of claim 3 , wherein the subset of ACKs comprises a last unique ACK of the plurality of ACKs and a set of earliest unique ACKs of the plurality of ACKs.

6. The method of claim 1 further comprising determining a number of ACKs present in a time interval, wherein the identifying is further in response to the number of ACKs present in the time interval satisfying an ACK count threshold condition.

7. The method of claim 6 , wherein the ACK count threshold condition depends on a category of the electronic device.

8. The method of claim 1 further comprising determining the memory utilization of the electronic device, wherein the identifying is further in response to the memory utilization satisfying a memory utilization threshold condition.

9. The method of claim 1 further comprising determining a thermal status of the electronic device, wherein the identifying is further in response to the thermal status satisfying a thermal level threshold condition.

10. The method of claim 1 , further comprising determining a capacity of a link transporting the plurality of ACKs, wherein the identifying is further in response to the capacity of the link satisfying a capacity level threshold condition.
